Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Nature of Business and Significant Accounting Policies	1. Organization, Nature of Business and Significant Accounting Policies Nature of Business Roadrunner Transportation Systems, Inc. (the “Company”) is headquartered in Cudahy, Wisconsin and has the following three operating segments: truckload logistics (“TL”); less-than-truckload (“LTL”); and Global Solutions. Within its TL business, the Company operates a network of 48 TL service centers, four freight consolidation and inventory management centers, and 23 dispatch offices and is augmented by over 100 independent brokerage agents. Within its LTL business, the Company operates 47 LTL service centers throughout the United States, complemented by relationships with over 180 delivery agents. Within its Global Solutions business, the Company operates from eight service centers and 11 dispatch offices throughout the United States. From pickup to delivery, the Company leverages relationships with a diverse group of third-party carriers to provide scalable capacity and reliable, customized service, including domestic and international air and ocean transportation services, to its customers. The Company operates primarily in the United States. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries. As of December 31, 2015 , all subsidiaries were 100% owned. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements, in conformity with accounting principles generally accepted in the United States (“GAAP”), requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Segment Reporting The Company determines its operating segments based on the information utilized by the chief operating decision maker, the Company’s Chief Executive Officer, to allocate resources and assess performance. Based on this information, the Company has determined that it has three operating segments: TL; LTL; and Global Solutions. Cash and Cash Equivalents Cash equivalents are defined as short-term investments that have an original maturity of three months or less at the date of purchase and are readily convertible into cash. The Company maintains cash in several banks and, at times, the balances may exceed federally insured limits. Cash equivalents consist of overnight investments in an interest bearing sweep account. Accounts Receivable and Related Reserves Accounts receivable represent trade receivables from customers and are stated net of an allowance for doubtful accounts and pricing allowances of approximately $3.8 million and $4.2 million as of December 31, 2015 and 2014 , respectively. Management estimates the portion of accounts receivable that will not be collected and accounts are written off when they are determined to be uncollectible. Accounts receivable are uncollateralized and are generally due 30 days from the invoice date. The Company provides reserves for accounts receivable. The rollforward of the allowance for doubtful accounts is as follows (in thousands): Year Ended December 31, 2015 2014 2013 Beginning balance $ 4,209 $ 2,957 $ 1,476 Provision, charged to expense 3,010 4,499 2,934 Write-offs, less recoveries (3,437 ) (3,247 ) (1,453 ) Ending balance $ 3,782 $ 4,209 $ 2,957 Property and Equipment Property and equipment are stated at cost. Maintenance and repair costs are charged to expense as incurred. For financial reporting purposes, depreciation is calculated using the straight-line method over the following estimated useful lives: Buildings and leasehold improvements 5-20 years Furniture and fixtures 5 years Equipment 3-15 years Accelerated depreciation methods are used for tax reporting purposes. Property and equipment and other long-lived assets are reviewed periodically for possible impairment. The Company evaluates whether current facts or circumstances indicate that the carrying value of the assets to be held and used may not be recoverable. If such circumstances are determined to exist, an estimate of undiscounted future cash flows produced by the long-lived asset, or the appropriate grouping of assets, is compared to the carrying value to determine whether impairment exists. If an asset is determined to be impaired, the loss is measured and recorded based on quoted market prices in active markets, if available. If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including discounted value of estimated future cash flows. The Company reports an asset to be disposed of at the lower of its carrying value or its fair value less the cost to sell. Goodwill and Other Intangibles Goodwill and other intangible assets result from business acquisitions. The Company accounts for business acquisitions by assigning the purchase price to tangible and intangible assets and liabilities. Assets acquired and liabilities assumed are recorded at their fair values and the excess of the purchase price over amounts assigned is recorded as goodwill. Goodwill is tested for impairment at least annually on July 1 using a two-step process that begins with an estimation of the fair value at the “reporting unit” level. The Company has four reporting units as this is the lowest level for which discrete financial information is prepared and regularly reviewed by segment management. The impairment test for goodwill involves comparing the fair value of a reporting unit to its carrying amount, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, a second step is required to measure the goodwill impairment loss. The second step includes valuing all the tangible and intangible assets of the reporting unit as if the reporting unit had been acquired in a business combination. Then, the implied fair value of the reporting unit’s goodwill is compared to the carrying amount of that goodwill. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of the goodwill, the Company recognizes an impairment loss in an amount equal to the excess, not to exceed the carrying amount. For purposes of the Company’s impairment test, the fair value of its reporting units is calculated based upon an average of an income fair value approach and market fair value approach. Based on these tests, the Company concluded that the fair value for each of the reporting units was in excess of the respective reporting unit’s carrying value. Accordingly, no goodwill impairments were identified in 2015 , 2014 , or 2013 . Other intangible assets recorded consist primarily of definite lived customer relationships. The Company evaluates its other intangible assets for impairment when current facts or circumstances indicate that the carrying value of the assets to be held and used may not be recoverable. No indicators of impairment were identified in 2015 , 2014 , or 2013 . See Note 4 for additional information on the Company's goodwill and intangible assets. Debt Issuance Costs Debt issuance costs represent costs incurred in connection with the financing agreement described in Note 6. The unamortized debt issuance costs aggregate to $6.6 million and $6.1 million as of December 31, 2015 and 2014 , respectively, and have been classified in the consolidated balance sheets as other noncurrent assets. Such costs are being amortized over the expected maturity of the financing agreements using the effective interest rate method. Share-Based Compensation The Company’s share-based payment awards are comprised of stock options, restricted stock units, and performance restricted stock units. The cost for the Company’s stock options is measured at fair value using the Black-Scholes option pricing model. The cost for restricted stock units and performance restricted stock units is measured using the stock price at the grant date. The cost is recognized over the vesting period of the award, which is typically four years. The amount of costs recognized for performance restricted stock units over the vesting period is dependent on the Company meeting the pre-established financial performance goals. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, the Company determines deferred tax assets and liabilities on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company recognizes deferred tax assets to the extent that it believes that these assets are more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. Fair Value of Financial Instruments The fair value of cash approximates cost. The estimated fair value of the Company's debt approximated its carrying value as of December 31, 2015 and 2014 as the debt agreement bears interest based on prevailing variable market rates currently available and as such would be categorized as a Level 2 in the fair value hierarchy as defined in Note 5. Revenue Recognition TL revenue is recorded when all of the following have occurred: an agreement of sale exists; pricing is fixed or determinable; delivery has occurred; the Company’s obligation to fulfill a transaction is complete; and collection of revenue is reasonably assured. This occurs when the Company completes the delivery of a shipment or the service has been fulfilled. LTL revenue is recorded when all of the following have occurred: an agreement of sale exists; pricing is fixed or determinable; and collection of revenue is reasonably assured. The Company recognizes revenue based on a percentage of services completed for freight in-transit as of the balance sheet date. Global Solutions revenue is recorded when the shipment has been delivered by a third-party carrier. Fees for services revenue is recognized when the services have been rendered. At the time of delivery or rendering of services, as applicable, the Company’s obligation to fulfill a transaction is complete and collection of revenue is reasonably assured. The Company offers volume discounts to certain customers. Revenue is reduced as discounts are earned. In some instances, the Company performs multiple services. Typically separate fees are quoted and recognized as revenue when services are rendered. Occasionally, customers request an all-inclusive "door-to-door" fee for a set of services and revenue is allocated to the elements and recognized as each service is completed. The Company typically recognizes revenue on a gross basis, as opposed to a net basis, because it bears the risks and benefits associated with revenue-generated activities by, among other things, (1) acting as a principal in the transaction, (2) establishing prices, (3) managing all aspects of the shipping process, and (4) taking the risk of loss for collection, delivery, and returns. Certain Global Solutions transactions to provide specific services are recorded at the net amount charged to the client due to the following factors: (A) the Company does not have latitude in establishing pricing and (B) the Company does not bear the risk of loss for delivery and returns; these items are the risk of the carrier. Insurance The Company uses a combination of purchased insurance and self-insurance programs to provide for the cost of vehicle liability, cargo damage, and workers’ compensation claims. The portion of self-insurance accruals which is included in accrued expenses and other liabilities relates primarily to vehicle liability and cargo damage claims. The Company periodically evaluates the level of insurance coverage and adjusts insurance levels based on risk tolerance and premium expense. The measurement and classification of self-insured costs requires the consideration of historical cost experience, demographic and severity factors, and judgments about the current and expected levels of cost per claim and retention levels. These methods provide estimates of the liability associated with claims incurred as of the balance sheet date, including claims not reported. The Company believes these methods are appropriate for measuring these judgmental self-insurance accruals. However, the use of any estimation method is sensitive to the assumptions and factors described above, based on the magnitude of claims and the length of time from the date the claim is incurred to ultimate settlement. Accordingly, changes in these assumptions and factors can materially affect actual costs paid to settle the claims and those amounts may be different than estimates. New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2014-09 (ASU 2014-09) which was updated in August 2015 by Accounting Standards Update No. 2015-14, Revenue from Contracts with Customers (Topic 606), which is effective for the Company in 2018. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company is in the process of evaluating the guidance in this Accounting Standards Update and has not yet determined if the adoption of this guidance will have a material impact on the Company’s consolidated financial statements. In April 2015, the FASB issued Accounting Standards Update No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30), which is effective for the Company in 2016 and must be applied retrospectively for all periods presented. This guidance simplifies the presentation of debt issuance costs. Under the revised Accounting Standard, the Company would be required to present debt issuance costs related to a recognized debt liability in the balance sheet as a direct deduction from the carrying amount of that debt liability. Amortization of the debt issuance costs should be reported as interest expense. The Accounting Standards Update does not affect the recognition and measurement for debt issuance costs. Debt issuance costs are currently recorded in other noncurrent assets and amortization of these debt issuance costs are currently reported as interest expense. Adoption of the revised Accounting Standard will require the company to reclass the balance of the debt issuance costs from a noncurrent asset to a direct reduction from the carrying amount of debt. In April 2015, the FASB issued Accounting Standards Update No. 2015-05, Intangibles-Goodwill and Other - Internal-Use Software (Subtopic 350-40), which is effective for the Company in 2016 and can be applied prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. This update provides guidance to help companies evaluate the accounting for fees paid by a customer in a cloud computing arrangement such as software as a service, infrastructure as a service, or other hosting arrangements. If a cloud computing arrangement includes a license to internal-use software, then the customer should account for the software license consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The Company is in the process of evaluating the guidance and has not yet determined if the adoption of this guidance will have a material impact on the Company's consolidated financial statements. In September 2015, the FASB issued Accounting Standards Update No. 2015-16, Simplifying the Accounting Measurement-Period Adjustments (Topic 805), which is effective for the Company in 2016. The amendments eliminate the requirement to retrospectively account for measurement period adjustments. The acquirer must record, in the period identified, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the changes to the provisional amounts, calculated as if the accounting had been completed as of the acquisition date. The acquirer must present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in the current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment had been recognized as of the acquisition date. Adoption of the revised Accounting Standard will require some additional disclosures in the footnotes to the consolidated financial statements. In November 2015, the FASB issued Accounting Standards Update no. 2015-17, Balance Sheet Classification of Deferred Taxes (Topic 740), which is effective for the Company in 2017. The amendments in this update require that deferred tax liabilities and assets be classified as noncurrent in the statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendment. The amendments may either be applied prospectively or retrospectively. The Company is in the process of evaluating the guidance and has not yet determined if the adoption of this guidance will have a material impact on the Company's consolidated financial statements.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	4. Goodwill and Intangible Assets Goodwill represents the excess of the purchase price of acquisitions over the estimated fair value of the net assets acquired. The Company evaluates goodwill and intangible assets for impairment at least annually or more frequently whenever events or changes in circumstances indicate that the asset may be impaired, or in the case of goodwill, the fair value of the reporting unit is below its carrying amount. The analysis of potential impairment of goodwill requires a two-step approach that begins with the estimation of the fair value at the reporting unit level. We have four reporting units for our three operating segments. We have one reporting unit for our LTL segment, two reporting units for our TL segment, and one reporting unit for our Global Solutions segment. For purposes of our impairment analysis, the fair value of the Company's reporting units is estimated based upon an average of an income fair value approach and a market fair value approach, both of which incorporate numerous assumptions and estimates such as company forecasts, discount rates, and growth rates, among others. The determination of fair value requires considerable judgment and is highly sensitive to changes in the underlying assumptions. The Company completed the annual impairment analysis as of July 1, 2015, and determined no impairment had occurred, as each reporting unit's calculated fair value exceeded the carrying value by at least 75% at the time of the evaluation. Subsequent to our annual impairment analysis as of July 1, 2015, a decline in revenues during the quarter ended September 30, 2015 resulted in a triggering event that required the Company to perform an interim goodwill impairment analysis of all reporting units as of September 30, 2015. The Company completed its interim impairment analysis and determined no impairment had occurred, as each reporting unit's calculated fair value exceeded the carrying value by at least 65% at the time of the evaluation. As a result, there is no goodwill impairment for any of the periods presented in the Company's condensed consolidated financial statements. The following is a rollforward of goodwill from December 31, 2013 to December 31, 2015 by reportable segment (in thousands): TL LTL Global Solutions Total Goodwill balance as of December 31, 2013 $ 211,413 $ 197,312 $ 110,018 $ 518,743 Adjustments to goodwill for purchase accounting (1,253 ) — 238 (1,015 ) Goodwill related to acquisitions 108,891 — 43,033 151,924 Goodwill balance as of December 31, 2014 $ 319,051 197,312 153,289 669,652 Adjustments to goodwill for purchase accounting 3,919 — 176 4,095 Goodwill related to acquisitions 17,371 — — 17,371 Goodwill balance as of December 31, 2015 $ 340,341 $ 197,312 $ 153,465 $ 691,118 Intangible assets consist primarily of customer relationships acquired from business acquisitions.

Fair Value Disclosures [Abstract]
Fair Value Measurement	5. Fair Value Measurement Accounting guidance on fair value measurements for certain financial assets and liabilities requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories: Level 1 — Quoted market prices in active markets for identical assets or liabilities. Level 2 — Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3 — Unobservable inputs reflecting the reporting entity’s own assumptions or external inputs from inactive markets. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement. Certain of the Company’s acquisitions contain contingent purchase obligations in the form of earn-outs as described in Note 3. The contingent purchase obligation related to acquisitions is measured at fair value on a recurring basis, according to the valuation techniques the Company uses to determine fair value. Changes to the fair value are recognized as income or expense within other operating expenses in the condensed consolidated statements of operations. In measuring the fair value of the contingent purchase obligation, the Company used an income approach that considers the expected future earnings of the acquired businesses, for the varying performance periods, based on historical performance and the resulting contingent payments, discounted at a risk-adjusted rate. The range of undiscounted outcomes for the estimated remaining contingent payments is zero to $14.4 million . The following table presents information, as of December 31, 2015 and 2014 , about the Company’s financial liabilities (in thousands): December 31, 2015 Level 1 Level 2 Level 3 Fair Value Contingent purchase price related to acquisitions $ — $ — $ 6,722 $ 6,722 Total liabilities at fair value $ — $ — $ 6,722 $ 6,722 December 31, 2014 Level 1 Level 2 Level 3 Fair Value Contingent purchase price related to acquisitions $ — $ — $ 7,665 $ 7,665 Total liabilities at fair value $ — $ — $ 7,665 $ 7,665 The table below sets forth a reconciliation of the Company’s beginning and ending Level 3 financial liability balance for the three years ended December 31 (in thousands): 2015 2014 2013 Balance, beginning of period $ 7,665 $ 17,054 $ 20,907 Earnouts related to acquisitions 4,114 — 4,288 Payment of contingent purchase obligations (3,317 ) (4,804 ) (2,407 ) Adjustments to contingent purchase obligations (1) (1,740 ) (4,585 ) (5,734 ) Balance, end of period $ 6,722 $ 7,665 $ 17,054 (1) Adjustments to contingent purchase obligations are reported in other operating expenses in the consolidated statements of operations.

The Company categorizes the borrowings under the credit agreement as Level 2 in the fair value hierarchy as defined in Note 5. The carrying value of the Company's long-term debt approximates fair value as the debt agreement bears interest based on prevailing variable market rates currently available. The credit agreement is collateralized by all assets of the Company and contains certain financial covenants, including a minimum fixed charge coverage ratio and a maximum cash flow leverage ratio. Additionally, the credit agreement contains negative covenants limiting, among other things, additional indebtedness, capital expenditures, transactions with affiliates, additional liens, sales of assets, dividends, investments, advances, prepayments of debt, mergers and acquisitions, and other matters customarily restricted in such agreements. The current debt agreement prohibits the Company from paying dividends without the consent of the lenders. Borrowings under the credit agreement bear interest at either (a) the Eurocurrency Rate (as defined in the credit agreement), plus an applicable margin in the range of 2.0% to 3.3% , or (b) the Base Rate (as defined in the credit agreement), plus an applicable margin in the range of 1.0% to 2.3% .

Stockholders' investment	7. Stockholders’ Investment Common Stock The Company's common stock has voting rights — one vote for each share of common stock. In March 2007, the Company entered into a second amended and restated stockholders’ agreement. The agreement provides that, any time after the Company is eligible to register its common stock on a Form S-3 registration statement under the Securities Act, certain of the Company’s stockholders may request registration under the Securities Act of all or any portion of their shares of common stock. These stockholders are limited to a total of two of such registrations. In addition, if the Company proposes to file a registration statement under the Securities Act for any underwritten sale of shares of any of its securities, certain of the Company's stockholders may request that the Company include in such registration the shares of common stock held by them on the same terms and conditions as the securities otherwise being sold in such registration. In December 2012 , the Company issued and sold shares of its common stock. Additionally, the Company granted the underwriters an option to purchase up to 525,000 additional shares at the public offering price less the underwriting discount to cover any over-allotments. In January 2013 , the underwriters exercised in full their over-allotment option to purchase an additional 525,000 shares of common stock at a price of $17.25 per share to the public. The sale of the additional shares resulted in net proceeds to the Company of approximately $8.5 million after deducting the underwriting discount and estimated expenses. In August 2013 , the Company issued 1.5 million shares of its common stock at a public offering price of $27.00 per share for aggregate offering proceeds of $38.4 million , net of $2.3 million of underwriting discounts and commissions and expenses. In connection with the public offering, the Company incurred additional expenses of $0.3 million . In August 2015 , in a secondary offering, affiliates of HCI Equity Partners, L.L.C. sold 2.0 million shares of common stock. The Company did not issue any shares in the offering and did not receive any proceeds from the sale of the shares; however, the Company incurred costs of $0.2 million . Warrants to Acquire Common Stock In connection with a business combination entered in 2007, the Company issued to existing Sargent Transportation Group, Inc. stockholders warrants that, upon the closing of the Company's initial public offering, became the right to acquire 2,269,263 shares of common stock at an exercise price of $13.39 per share. The warrants are exercisable at the option of the holder any time prior to March 13, 2017 . No warrants were exercised during the year ended December 31, 2015 or 2014 . On December 11, 2009, in connection with financing the acquisition of Bullet Freight Systems, Inc. ("Bullet"), the Company issued warrants that, upon the closing of the Company's initial public offering, became the right to acquire 1,746,971 shares of common stock at an exercise price of $8.37 per share. The warrants are exercisable at the option of the holder any time prior to December 11, 2017 . No warrants were exercised during the year ended December 31, 2015 or 2014 . The $3.0 million fair value of the warrants at the date of issuance has been reflected as a component of additional paid-in capital in stockholders’ investment in the accompanying consolidated balance sheets.

Share-Based Compensation	8. Share-Based Compensation The Company's 2010 Incentive Compensation Plan (the “2010 Plan”) allows for the issuance of 2,500,000 shares of common stock. The 2010 Plan provides for the grant of stock options, restricted stock units, and other awards to the Company's employees and directors. In 2015 , the Company added performance restricted stock units to its share-based compensation plan. Under the new program, performance restricted stock units were awarded to eligible employees based on pre-established financial performance goals. No performance restricted stock unit awards were earned as of December 31, 2015 . The Company awards restricted stock units to certain key employees and non-employee directors. The restricted stock units vest ratably over a four year service period from the grant date. Restricted stock units are valued based on the market price on the date of the grant and are amortized on a straight-line basis over the vesting period. Compensation expense for restricted stock units is based on fair market value at the grant date. The following table summarizes the nonvested restricted stock units as of December 31, 2015 and 2014 : Number of Restricted Stock Units Weighted Average Grant Date Fair Value Weighted Average Remaining Contractual Term (Years) Nonvested as of December 31, 2013 279,471 $ 21.76 2.8 Granted 169,300 22.89 Vested (87,061 ) 20.30 Forfeitures (29,574 ) 22.25 Nonvested as of December 31, 2014 332,136 $ 22.76 2.5 Granted 19,051 23.60 Vested (111,180 ) 21.34 Forfeitures (31,232 ) 23.17 Nonvested as of December 31, 2015 208,775 $ 23.75 1.7 Unrecognized stock compensation expense was $3.1 million and $5.7 million for the years ended December 31, 2015 and 2014 , respectively.

Earnings Per Share [Abstract]
Earnings Per Share	9. Earnings Per Share Basic earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of common stock outstanding during the period. Diluted earnings per share is calculated by dividing net income available to common stockholders by the weighted average common stock outstanding plus stock equivalents that would arise from the assumed exercise of stock options and conversion of warrants using the treasury stock method. The Company had stock options and warrants outstanding of 253,834 as of December 31, 2015 that were not included in the computation of diluted earnings per share because they were not assumed to be exercised under the treasury stock method or because they were anti-dilutive. As of December 31, 2014 and 2013 , all stock options and warrants were included in the computation of diluted earnings per share.

Guarantees [Abstract]
Guarantees [Text Block]	11. Guarantees The Company provides a guarantee for a portion of the value of certain independent contractors' ("IC") leased tractors. The guarantees expire at various dates through 2020 . The potential maximum exposure under these lease guarantees was approximately $17.4 million as of December 31, 2015 . The potential maximum exposure represents the Company’s commitment on remaining lease payments on guaranteed leases as of December 31, 2015 . However, upon an IC default, the Company has the option to purchase the tractor or return the tractor to the leasing company if the residual value is greater than the Company’s guarantee. Alternatively, the Company can contract another IC to assume the lease. The declining quality and performance of the equipment in certain lease purchase programs caused escalating repair and maintenance expenses for the Company's ICs, which, coupled with the softened demand experienced during the third quarter of 2015 , resulted in increased turnover and default by certain ICs. As a result, the Company experienced an acceleration of its IC recruiting costs, guarantee payments, and reseating and reconditioning costs associated with these lease purchase programs. Accordingly, the Company decided to terminate certain lease purchase guarantee programs in favor of new lease purchase programs that do not involve a guarantee from the Company and utilize newer equipment under warranty. As of December 31, 2015 , the Company had a reserve of $1.3 million for the termination of certain lease purchase guarantee programs. The Company made payments of $3.7 million for the year ended December 31, 2015 . Payments made for the year ended December 31, 2014 were de minimis.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	12. Commitments and Contingencies Employee Benefit Plans The Company sponsors defined contribution profit sharing plans for substantially all employees of the Company and its subsidiaries. The Company provides matching contributions on some of these plans. Total expense under these plans was $2.8 million , $2.3 million , and $1.4 million for the years ended December 31, 2015 , 2014 , and 2013 , respectively. Operating Leases The Company leases terminals, office space, trucks, trailers, and other equipment under noncancelable operating leases expiring on various dates through 2027. The Company incurred rent expense from operating leases of $66.2 million , $55.0 million , and $28.7 million for the years ended December 31, 2015 , 2014 , and 2013 , respectively. Aggregate future minimum lease payments under noncancelable operating leases with an initial term in excess of one year were as follows as of December 31, 2015 (in thousands): Year Ending: Amount 2016 $ 48,117 2017 39,236 2018 32,059 2019 17,813 2020 11,402 Thereafter 20,203 Contingencies In the ordinary course of business, the Company is a defendant in several legal proceedings arising out of the conduct of its business. These proceedings include claims for property damage or personal injury incurred in connection with the Company’s services. Although there can be no assurance as to the ultimate disposition of these proceedings, the Company does not believe, based upon the information available at this time, that these property damage or personal injury claims, in the aggregate, will have a material impact on its consolidated financial statements. The Company maintains liability insurance coverage for claims in excess of $500,000 per occurrence and cargo coverage for claims in excess of $100,000 per occurrence. The Company believes it has adequate insurance to cover losses in excess of the deductible amount. As of December 31, 2015 and December 31, 2014 , the Company had reserves for estimated uninsured losses of $7.2 million and $5.8 million , respectively. In addition to the legal proceedings described above, like many others in the transportation services industry, the Company is a defendant in five purported class-action lawsuits in California alleging violations of various California labor laws and one purported class-action lawsuit in Illinois alleging violations of the Illinois Wage Payment and Collection Act. The plaintiffs in each of these lawsuits seek to recover unspecified monetary damages and other items. In addition, the California Division of Labor Standards and Enforcement has brought administrative actions against the Company on behalf of seven individuals alleging that the Company violated California labor laws. Given the early stage of all of the proceedings described in this paragraph, the Company is not able to assess with certainty the outcome of these proceedings or the amount or range of potential damages or future payments associated with these proceedings at this time. The Company believes it has meritorious defenses to these actions and intends to defend these proceedings vigorously. However, any legal proceeding is subject to inherent uncertainties, and the Company cannot assure that the expenses associated with defending these actions or their resolution will not have a material adverse effect on its business, operating results, or financial condition.

Segment Reporting [Abstract]
Segment Reporting	14. Segment Reporting The Company determines its operating segments based on the information utilized by the chief operating decision maker, the Company’s Chief Executive Officer, to allocate resources and assess performance. Based on this information, the Company has determined that it has three operating segments: TL; LTL; and Global Solutions. These segments are strategic business units through which the Company offers different services. The Company evaluates the performance of the segments primarily based on their respective revenues and operating income. Accordingly, interest expense and other non-operating items are not reported in segment results. In addition, the Company has disclosed a corporate segment, which is not an operating segment and includes acquisition transaction expenses, corporate salaries, and share-based compensation expense. The following table reflects certain financial data of the Company’s reportable segments (in thousands): Year Ended December 31, 2015 2014 2013 Revenues: TL 1,175,594 999,077 657,967 LTL 516,251 577,175 558,971 Global Solutions 330,319 311,362 154,050 Eliminations (27,145 ) (14,798 ) (9,578 ) Total 1,995,019 1,872,816 1,361,410 Operating income: TL 73,867 66,186 43,385 LTL 20,164 22,981 36,914 Global Solutions 25,070 21,924 14,742 Corporate (22,428 ) (15,405 ) (9,678 ) Total operating income 96,673 95,686 85,363 Interest expense 19,439 13,363 7,883 Income before provision for income taxes $ 77,234 $ 82,323 $ 77,480 Depreciation and amortization: TL 23,489 16,888 11,143 LTL 3,309 3,287 3,255 Global Solutions 4,118 3,732 1,665 Corporate 1,407 1,171 248 Total $ 32,323 $ 25,078 $ 16,311 Capital expenditures (1) : TL 48,797 34,620 23,128 LTL 13,107 5,840 4,744 Global Solutions 3,103 1,551 668 Corporate 2,293 2,966 3,006 Total $ 67,300 $ 44,977 $ 31,546 (1) The total capital expenditures for the year ended December 31, 2015 includes both the cash and non-cash portions as reflected in the Consolidated Statement of Cash Flows.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business	Nature of Business Roadrunner Transportation Systems, Inc. (the “Company”) is headquartered in Cudahy, Wisconsin and has the following three operating segments: truckload logistics (“TL”); less-than-truckload (“LTL”); and Global Solutions. Within its TL business, the Company operates a network of 48 TL service centers, four freight consolidation and inventory management centers, and 23 dispatch offices and is augmented by over 100 independent brokerage agents. Within its LTL business, the Company operates 47 LTL service centers throughout the United States, complemented by relationships with over 180 delivery agents. Within its Global Solutions business, the Company operates from eight service centers and 11 dispatch offices throughout the United States. From pickup to delivery, the Company leverages relationships with a diverse group of third-party carriers to provide scalable capacity and reliable, customized service, including domestic and international air and ocean transportation services, to its customers. The Company operates primarily in the United States.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries. As of December 31, 2015 , all subsidiaries were 100% owned. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements, in conformity with accounting principles generally accepted in the United States (“GAAP”), requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Segment Reporting	Segment Reporting The Company determines its operating segments based on the information utilized by the chief operating decision maker, the Company’s Chief Executive Officer, to allocate resources and assess performance. Based on this information, the Company has determined that it has three operating segments: TL; LTL; and Global Solutions.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash equivalents are defined as short-term investments that have an original maturity of three months or less at the date of purchase and are readily convertible into cash. The Company maintains cash in several banks and, at times, the balances may exceed federally insured limits. Cash equivalents consist of overnight investments in an interest bearing sweep account.
Account Receivable	Accounts Receivable and Related Reserves Accounts receivable represent trade receivables from customers and are stated net of an allowance for doubtful accounts and pricing allowances of approximately $3.8 million and $4.2 million as of December 31, 2015 and 2014 , respectively. Management estimates the portion of accounts receivable that will not be collected and accounts are written off when they are determined to be uncollectible. Accounts receivable are uncollateralized and are generally due 30 days from the invoice date. The Company provides reserves for accounts receivable. The rollforward of the allowance for doubtful accounts is as follows (in thousands): Year Ended December 31, 2015 2014 2013 Beginning balance $ 4,209 $ 2,957 $ 1,476 Provision, charged to expense 3,010 4,499 2,934 Write-offs, less recoveries (3,437 ) (3,247 ) (1,453 ) Ending balance $ 3,782 $ 4,209 $ 2,957
Property and Equipment	Property and Equipment Property and equipment are stated at cost. Maintenance and repair costs are charged to expense as incurred. For financial reporting purposes, depreciation is calculated using the straight-line method over the following estimated useful lives: Buildings and leasehold improvements 5-20 years Furniture and fixtures 5 years Equipment 3-15 years Accelerated depreciation methods are used for tax reporting purposes. Property and equipment and other long-lived assets are reviewed periodically for possible impairment. The Company evaluates whether current facts or circumstances indicate that the carrying value of the assets to be held and used may not be recoverable. If such circumstances are determined to exist, an estimate of undiscounted future cash flows produced by the long-lived asset, or the appropriate grouping of assets, is compared to the carrying value to determine whether impairment exists. If an asset is determined to be impaired, the loss is measured and recorded based on quoted market prices in active markets, if available. If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including discounted value of estimated future cash flows. The Company reports an asset to be disposed of at the lower of its carrying value or its fair value less the cost to sell.
Goodwill and Other Intangibles	Goodwill and Other Intangibles Goodwill and other intangible assets result from business acquisitions. The Company accounts for business acquisitions by assigning the purchase price to tangible and intangible assets and liabilities. Assets acquired and liabilities assumed are recorded at their fair values and the excess of the purchase price over amounts assigned is recorded as goodwill. Goodwill is tested for impairment at least annually on July 1 using a two-step process that begins with an estimation of the fair value at the “reporting unit” level. The Company has four reporting units as this is the lowest level for which discrete financial information is prepared and regularly reviewed by segment management. The impairment test for goodwill involves comparing the fair value of a reporting unit to its carrying amount, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, a second step is required to measure the goodwill impairment loss. The second step includes valuing all the tangible and intangible assets of the reporting unit as if the reporting unit had been acquired in a business combination. Then, the implied fair value of the reporting unit’s goodwill is compared to the carrying amount of that goodwill. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of the goodwill, the Company recognizes an impairment loss in an amount equal to the excess, not to exceed the carrying amount. For purposes of the Company’s impairment test, the fair value of its reporting units is calculated based upon an average of an income fair value approach and market fair value approach. Based on these tests, the Company concluded that the fair value for each of the reporting units was in excess of the respective reporting unit’s carrying value. Accordingly, no goodwill impairments were identified in 2015 , 2014 , or 2013 . Other intangible assets recorded consist primarily of definite lived customer relationships. The Company evaluates its other intangible assets for impairment when current facts or circumstances indicate that the carrying value of the assets to be held and used may not be recoverable. No indicators of impairment were identified in 2015 , 2014 , or 2013 . See Note 4 for additional information on the Company's goodwill and intangible assets.
Debt Issuance Costs	Debt Issuance Costs Debt issuance costs represent costs incurred in connection with the financing agreement described in Note 6. The unamortized debt issuance costs aggregate to $6.6 million and $6.1 million as of December 31, 2015 and 2014 , respectively, and have been classified in the consolidated balance sheets as other noncurrent assets. Such costs are being amortized over the expected maturity of the financing agreements using the effective interest rate method.
Share-Based Compensation	Share-Based Compensation The Company’s share-based payment awards are comprised of stock options, restricted stock units, and performance restricted stock units. The cost for the Company’s stock options is measured at fair value using the Black-Scholes option pricing model. The cost for restricted stock units and performance restricted stock units is measured using the stock price at the grant date. The cost is recognized over the vesting period of the award, which is typically four years.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, the Company determines deferred tax assets and liabilities on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company recognizes deferred tax assets to the extent that it believes that these assets are more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value of cash approximates cost. The estimated fair value of the Company's debt approximated its carrying value as of December 31, 2015 and 2014 as the debt agreement bears interest based on prevailing variable market rates currently available and as such would be categorized as a Level 2 in the fair value hierarchy as defined in Note 5.
Revenue Recognition	Revenue Recognition TL revenue is recorded when all of the following have occurred: an agreement of sale exists; pricing is fixed or determinable; delivery has occurred; the Company’s obligation to fulfill a transaction is complete; and collection of revenue is reasonably assured. This occurs when the Company completes the delivery of a shipment or the service has been fulfilled. LTL revenue is recorded when all of the following have occurred: an agreement of sale exists; pricing is fixed or determinable; and collection of revenue is reasonably assured. The Company recognizes revenue based on a percentage of services completed for freight in-transit as of the balance sheet date. Global Solutions revenue is recorded when the shipment has been delivered by a third-party carrier. Fees for services revenue is recognized when the services have been rendered. At the time of delivery or rendering of services, as applicable, the Company’s obligation to fulfill a transaction is complete and collection of revenue is reasonably assured. The Company offers volume discounts to certain customers. Revenue is reduced as discounts are earned. In some instances, the Company performs multiple services. Typically separate fees are quoted and recognized as revenue when services are rendered. Occasionally, customers request an all-inclusive "door-to-door" fee for a set of services and revenue is allocated to the elements and recognized as each service is completed. The Company typically recognizes revenue on a gross basis, as opposed to a net basis, because it bears the risks and benefits associated with revenue-generated activities by, among other things, (1) acting as a principal in the transaction, (2) establishing prices, (3) managing all aspects of the shipping process, and (4) taking the risk of loss for collection, delivery, and returns. Certain Global Solutions transactions to provide specific services are recorded at the net amount charged to the client due to the following factors: (A) the Company does not have latitude in establishing pricing and (B) the Company does not bear the risk of loss for delivery and returns; these items are the risk of the carrier.
Insurance	Insurance The Company uses a combination of purchased insurance and self-insurance programs to provide for the cost of vehicle liability, cargo damage, and workers’ compensation claims. The portion of self-insurance accruals which is included in accrued expenses and other liabilities relates primarily to vehicle liability and cargo damage claims. The Company periodically evaluates the level of insurance coverage and adjusts insurance levels based on risk tolerance and premium expense. The measurement and classification of self-insured costs requires the consideration of historical cost experience, demographic and severity factors, and judgments about the current and expected levels of cost per claim and retention levels. These methods provide estimates of the liability associated with claims incurred as of the balance sheet date, including claims not reported. The Company believes these methods are appropriate for measuring these judgmental self-insurance accruals. However, the use of any estimation method is sensitive to the assumptions and factors described above, based on the magnitude of claims and the length of time from the date the claim is incurred to ultimate settlement. Accordingly, changes in these assumptions and factors can materially affect actual costs paid to settle the claims and those amounts may be different than estimates.
New Accounting Pronouncements	New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2014-09 (ASU 2014-09) which was updated in August 2015 by Accounting Standards Update No. 2015-14, Revenue from Contracts with Customers (Topic 606), which is effective for the Company in 2018. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company is in the process of evaluating the guidance in this Accounting Standards Update and has not yet determined if the adoption of this guidance will have a material impact on the Company’s consolidated financial statements. In April 2015, the FASB issued Accounting Standards Update No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30), which is effective for the Company in 2016 and must be applied retrospectively for all periods presented. This guidance simplifies the presentation of debt issuance costs. Under the revised Accounting Standard, the Company would be required to present debt issuance costs related to a recognized debt liability in the balance sheet as a direct deduction from the carrying amount of that debt liability. Amortization of the debt issuance costs should be reported as interest expense. The Accounting Standards Update does not affect the recognition and measurement for debt issuance costs. Debt issuance costs are currently recorded in other noncurrent assets and amortization of these debt issuance costs are currently reported as interest expense. Adoption of the revised Accounting Standard will require the company to reclass the balance of the debt issuance costs from a noncurrent asset to a direct reduction from the carrying amount of debt. In April 2015, the FASB issued Accounting Standards Update No. 2015-05, Intangibles-Goodwill and Other - Internal-Use Software (Subtopic 350-40), which is effective for the Company in 2016 and can be applied prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. This update provides guidance to help companies evaluate the accounting for fees paid by a customer in a cloud computing arrangement such as software as a service, infrastructure as a service, or other hosting arrangements. If a cloud computing arrangement includes a license to internal-use software, then the customer should account for the software license consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The Company is in the process of evaluating the guidance and has not yet determined if the adoption of this guidance will have a material impact on the Company's consolidated financial statements. In September 2015, the FASB issued Accounting Standards Update No. 2015-16, Simplifying the Accounting Measurement-Period Adjustments (Topic 805), which is effective for the Company in 2016. The amendments eliminate the requirement to retrospectively account for measurement period adjustments. The acquirer must record, in the period identified, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the changes to the provisional amounts, calculated as if the accounting had been completed as of the acquisition date. The acquirer must present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in the current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment had been recognized as of the acquisition date. Adoption of the revised Accounting Standard will require some additional disclosures in the footnotes to the consolidated financial statements. In November 2015, the FASB issued Accounting Standards Update no. 2015-17, Balance Sheet Classification of Deferred Taxes (Topic 740), which is effective for the Company in 2017. The amendments in this update require that deferred tax liabilities and assets be classified as noncurrent in the statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendment. The amendments may either be applied prospectively or retrospectively. The Company is in the process of evaluating the guidance and has not yet determined if the adoption of this guidance will have a material impact on the Company's consolidated financial statements.
