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 transportation management solutions (“TMS”). Within its TL business, the Company operates a network of 46 TL service centers, five freight consolidation and inventory management centers, and 24 company dispatch offices and is augmented by over 100 independent brokerage agents. Within its LTL business, the Company operates 45 LTL service centers throughout the United States, complemented by relationships with over 160 delivery agents. Within its TMS business, the Company operates from 11 service centers and nine 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 accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany balances and transactions have been eliminated in consolidation. In the Company's opinion, these financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the operations for the interim periods presented. Interim results are not necessarily indicative of results for a full year. 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 as of 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, which are also its reportable segments: TL, LTL, and TMS. New Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606), which is effective for the Company in 2017. 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. Early adoption of the revised Accounting Standard is permitted. 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 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.

Fair Value Measurement

Fair Value Disclosures [Abstract]
Fair value measurement	4. 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’s or liability’s classification within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement. The contingent purchase price related to acquisitions is measured at fair value on a recurring basis, according to the valuation techniques the Company used to determine fair value. The following table presents information, as of June 30, 2015 and December 31, 2014 , about the Company’s financial liabilities (in thousands): June 30, 2015 Level 1 Level 2 Level 3 Fair Value Contingent purchase price related to acquisitions $ — $ — $ 3,481 $ 3,481 Total liabilities at fair value $ — $ — $ 3,481 $ 3,481 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 In measuring the fair value of the contingent purchase price liability, the Company used an income approach that considers the expected future earnings of the acquired businesses based on historical performance and the resulting contingent payments, discounted at a risk-adjusted rate. The table below sets forth a reconciliation of the Company’s beginning and ending Level 3 financial liability balance for the three and six months ended June 30, 2015 and 2014 and the year ended December 31, 2014 (in thousands): Three Months Ended Six Months Ended Year Ended June 30, June 30, December 31, 2015 2014 2015 2014 2014 Balance, beginning of period $ 5,708 $ 17,249 $ 7,665 $ 17,054 $ 17,054 Payments of contingent purchase obligations (1,360 ) (4,804 ) (3,317 ) (4,804 ) (4,804 ) Adjustments to contingent purchase obligations (867 ) (719 ) (867 ) (524 ) (4,585 ) Balance, end of period $ 3,481 $ 11,726 $ 3,481 $ 11,726 $ 7,665

Long-Term Debt Long-term debt as of June 30, 2015 and December 31, 2014 consisted of the following (in thousands): June 30, December 31, Senior debt: Revolving credit facility $ 240,000 $ 235,000 Term loan 190,000 195,000 Total debt 430,000 430,000 Less: Current maturities (10,000 ) (10,000 ) Total long-term debt, net of current maturities $ 420,000 $ 420,000 On July 9, 2014 , the Company entered into a fifth amended and restated credit agreement (the "credit agreement") with U.S. Bank National Association and other lenders, which increased the revolving credit facility from $200.0 million to $350.0 million and the term loan from $175.0 million to $200.0 million . The credit facility matures on July 9, 2019 . Principal on the term loan is due in quarterly installments of $2.5 million . The Company categorizes the borrowings under the credit agreement as Level 2 in the fair value hierarchy as defined in Note 4. 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 3.0% , or (b) the Base Rate (as defined in the credit agreement), plus an applicable margin in the range of 1.0% to 2.0% . The revolving credit facility also provides for the issuance of up to $30.0 million in letters of credit. As of June 30, 2015 , the Company had outstanding letters of credit totaling $20.7 million . As of June 30, 2015 , total availability under the revolving credit facility was $89.3 million and the average interest rate on the credit agreement was 3.2% .

Earnings Per Share [Abstract]
Earnings Per Share	7. Earnings Per Share Basic earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding during the period. For the three and six months ended June 30, 2015 and 2014 , diluted earnings per share was 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, the conversion of warrants, and the delivery of stock underlying restricted stock units using the treasury stock method. There is no difference, for any of the periods presented, in the amount of net income available to common stockholders used in the computation of basic and diluted earnings per share. As of June 30, 2015 and 2014 , all stock options, warrants, and restricted stock units were included in the computation of diluted earnings per share. The following table reconciles basic weighted average common stock outstanding to diluted weighted average common stock outstanding (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2015 2014 2015 2014 Basic weighted average common stock outstanding 38,170 37,868 38,090 37,779 Effect of dilutive securities Employee stock options 93 180 109 201 Warrants 1,220 1,238 1,180 1,220 Restricted stock units 41 44 53 54 Diluted weighted average common stock outstanding 39,524 39,330 39,432 39,254

Income Taxes	8. Income Taxes The effective income tax rate was 38.7% for both the three and six months ended June 30, 2015 and 2014 . In determining the provision for income taxes, the Company used an estimated annual effective tax rate, which was based on expected annual income, statutory tax rates, and the Company's best estimate of non-deductible and non-taxable items of income and expense. Income tax expense varies from the amount computed by applying the federal corporate income tax rate of 35.0% to income before income taxes primarily due to state income taxes, net of federal income tax effect, and adjustments for permanent differences.

Guarantees [Abstract]
Guarantees	9. 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 $17.8 million as of June 30, 2015 . The potential maximum exposure represents the Company’s commitment on remaining lease payments on guaranteed leases as of June 30, 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. There were no material IC defaults during the three and six months ended June 30, 2015 and 2014 . Payments made by the Company under the guarantees were de minimis for the three and six months ended June 30, 2015 and 2014 . No liability related to these lease guarantees was recorded as of June 30, 2015 or December 31, 2014 .

The Company believes it has adequate insurance to cover losses in excess of the deductible amount. As of June 30, 2015 and December 31, 2014 , the Company had reserves for estimated uninsured losses of $5.9 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 three purported class-action lawsuits in California alleging violations of various California labor laws. 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 six 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 you 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	12. 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, which are also its reportable segments: TL, LTL, and TMS. These reportable 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 for the three and six months ended June 30, 2015 and 2014 and as of June 30, 2015 and December 31, 2014 (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2015 2014 2015 2014 Revenues: TL $ 295,465 $ 230,789 $ 577,663 $ 424,674 LTL 138,943 150,162 270,588 285,163 TMS 89,706 81,829 171,735 138,455 Eliminations (6,184 ) (2,599 ) (13,086 ) (6,081 ) Total 517,930 460,181 1,006,900 842,211 Operating income: TL $ 20,538 $ 16,061 $ 36,443 $ 28,026 LTL 8,367 7,931 17,026 14,676 TMS 7,680 6,089 13,511 9,565 Corporate (5,343 ) (3,128 ) (8,936 ) (6,075 ) Total operating income 31,242 26,953 58,044 46,192 Interest expense 4,373 2,859 8,982 5,109 Income before provision for income taxes $ 26,869 $ 24,094 $ 49,062 $ 41,083 Depreciation and amortization: TL $ 5,465 $ 3,602 $ 10,178 $ 6,784 LTL 737 962 1,572 1,619 TMS 996 749 1,997 1,467 Corporate 337 413 665 599 Total $ 7,535 $ 5,726 $ 14,412 $ 10,469 Capital expenditures (1) (2) : TL $ 7,457 $ 6,842 $ 21,619 $ 16,259 LTL 3,447 468 4,271 2,179 TMS 287 814 448 1,017 Corporate 7,166 1,156 7,852 2,026 Total $ 18,357 $ 9,280 $ 34,190 $ 21,481 (1) The total capital expenditures for the three and six months ended June 30, 2015 and June 30, 2014 includes both cash and non-cash portions as reflected in the Condensed Consolidated Statements 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 transportation management solutions (“TMS”). Within its TL business, the Company operates a network of 46 TL service centers, five freight consolidation and inventory management centers, and 24 company dispatch offices and is augmented by over 100 independent brokerage agents. Within its LTL business, the Company operates 45 LTL service centers throughout the United States, complemented by relationships with over 160 delivery agents. Within its TMS business, the Company operates from 11 service centers and nine 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 accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany balances and transactions have been eliminated in consolidation. In the Company's opinion, these financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the operations for the interim periods presented. Interim results are not necessarily indicative of results for a full year.
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 as of 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, which are also its reportable segments: TL, LTL, and TMS.
New Accounting Pronouncements	New Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606), which is effective for the Company in 2017. 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. Early adoption of the revised Accounting Standard is permitted. 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 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.
