Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	GENERAL Description of Business In this report, when we refer to “the Company,” “us,” “we,” “our,” or “ours,” we are referring to Schneider National, Inc. and its subsidiaries. We are a leading transportation services organization headquartered in Green Bay, Wisconsin. We provide a broad portfolio of premier truckload, intermodal, and logistics solutions and operate one of the largest trucking fleets in North America. Our IPO of shares of Class B Common Stock was completed in early April 2017, and additional shares were sold in May 2017 under an option granted to the underwriters. In connection with the offering, we sold a total of 20,145,000 shares of common stock at $19 per share and received proceeds of $382,755 . Expenses related to the offering totaled approximately $42,108 , resulting in net proceeds of $340,647 . Basis of Presentation The accompanying unaudited interim Condensed Consolidated Financial Statements have been prepared in accordance with GAAP and the rules and regulations of the SEC applicable to quarterly reports on Form 10-Q. Therefore, these financial statements and footnotes do not include all disclosures required by GAAP for annual financial statements. These financial statements should be read in conjunction with the Consolidated Financial Statements and related notes included in our Prospectus. Financial results for an interim period are not necessarily indicative of the results for a full year. All intercompany transactions have been eliminated in consolidation. In the opinion of management, these statements reflect all adjustments (consisting only of normal recurring adjustments) necessary for the fair presentation of our financial results for the interim periods presented. Accounting Standards Issued But Not Yet Adopted In May 2014, the FASB issued ASU 2014-9, Revenue from Contracts with Customers. This guidance outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. As amended, the new revenue recognition standard will be effective for us beginning with the reporting period ending March 31, 2018. The standard permits the use of either the full retrospective or modified retrospective transition method. We are in the process of reviewing and assessing our contracts with customers in accordance with the guidance in the ASU. Based on our analysis to date, we do not expect the adoption of this ASU to have a material impact on our consolidated financial position, results of operations, and cash flows. We plan to use the modified retrospective approach for adoption, which requires us to record the cumulative effect of the transition through retained earnings as of January 1, 2018. We are still evaluating the disclosure requirements of this standard. In January 2016, the FASB issued ASU 2016-1, Financial Instruments–Overall: Recognition and Measurement of Financial Assets and Financial Liabilities . This update was issued to enhance the reporting model for financial instruments regarding certain aspects of recognition, measurement, presentation, and disclosure. These provisions are effective for us beginning with the reporting period ending March 31, 2018. The standard is to be applied using a cumulative-effect adjustment to the balance sheet as of the beginning of the year of adoption. We do not expect the adoption of this ASU to have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-2, Leases , which requires lessees to recognize in the consolidated balance sheets assets and liabilities for leases with lease terms of more than 12 months. Consistent with current accounting principles, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. However, unlike current accounting principles, which require only capital leases to be recognized in the consolidated balance sheets, the new ASU will require both types of leases to be recognized in the consolidated balance sheets. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that companies may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. The transition guidance also provides specific guidance for sale and leaseback transactions, build-to-suit leases, leveraged leases, and amounts previously recognized in accordance with the business combinations guidance for leases. The new standard is effective for us beginning with the reporting period ending March 31, 2019, with early adoption permitted. We currently cannot reasonably estimate the impact that the adoption of this ASU will have on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments , which requires companies to use a forward-looking, expected loss model to estimate credit losses on various types of financial assets and net investments in leases. It also requires additional disclosure related to credit quality of trade and other receivables, including information related to management’s estimate of credit allowances. This guidance is effective for us beginning with the reporting period ending March 31, 2020. We currently cannot reasonably estimate the impact that the adoption of this ASU will have on our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments , which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. Entities must apply the guidance retrospectively to all periods presented but may apply it prospectively if retrospective application would be impracticable. The provisions of this update are effective for us beginning with the reporting period ending March 31, 2018. We currently cannot reasonably estimate the impact that the adoption of this ASU will have on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-4 , Intangibles—Goodwill and Other: Simplifying the Test for Goodwill Impairment, which eliminates Step 2 from the goodwill impairment testing process. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount. Under the new standard, a goodwill impairment loss is measured as the excess of the carrying value of a reporting unit over its fair value. The provisions of this update will be effective for our goodwill impairment test in 2020. We currently cannot reasonably estimate the impact that the adoption of this ASU will have on our consolidated financial statements.

Acquisition

Business Combinations [Abstract]
Acquisition	ACQUISITION On June 1, 2016, we acquired 100% of the shares of WSL, for $150,420 in cash and future payments. WSL brings together final-mile delivery, claims-free handling, and an innovative technology platform. It provides LTL, truckload, and logistics services for difficult to handle goods, such as furniture and floor coverings, across North America. It uses proprietary technology to handle supply chain complexities within the national home delivery industry. We acquired WSL because it creates integrated first-to-final-mile-delivery capabilities, which reduces supply chain complexities for omnichannel retailers and manufacturers. The acquisition was accounted for as a purchase in accordance with FASB Accounting Standards Codification Topic 805, Business Combinations . Assets acquired and liabilities assumed were recorded in the Truckload segment at their fair values as of the acquisition date. The fair values of identifiable intangible assets, which were primarily customer relationships and trade names, were based on valuations using the income approach. The excess of the purchase price over the estimated fair values of tangible assets, identifiable intangible assets, and assumed liabilities was recorded as goodwill. The goodwill is attributable to expected synergies and expected growth opportunities. We believe that 100% of the goodwill will be deductible for United States income tax purposes. No adjustments were made to the estimated fair values of the assets acquired and liabilities assumed during the six months ended June 30, 2017 . Recognized amounts of identifiable assets acquired and liabilities assumed Cash $ 1,318 Receivables 16,156 Inventories 480 Prepaid expenses and other current assets 4,392 Property and equipment 81,844 Capitalized software and other noncurrent assets 5,807 Intangible assets 10,900 Goodwill 138,168 Total assets acquired 259,065 Payables assumed 7,807 Accrued liabilities assumed 5,289 Current maturities of debt and capital lease obligations assumed 47,692 Debt and capital lease obligations assumed 46,211 Other noncurrent liabilities assumed 1,646 Fair value of total consideration transferred $ 150,420 In addition to the cash paid at closing, the purchase and sale agreement included guaranteed payments of $20,000 to the former owners of WSL on each of the first three anniversary dates of the closing. The liability recorded was discounted between one percent and three percent , based on credit-adjusted discount rates. The initial payment in the amount of $19,668 , including calculated interest based on the discounted amount recorded, was made in June 2017 and reflected an adjustment for a working capital true-up. The total present value of the remaining two payments was $37,998 at June 30, 2017 . A contingent payment arrangement based on the achievement of specified earnings targets is also in place for three consecutive 12 month periods after the closing, with the aggregate payment total not to exceed $40,000 . No payments have been made through June 30, 2017 . See Note 3 , Fair Value , for information regarding the fair value of this contingent arrangement. The following unaudited pro forma condensed combined financial information presents our results as if we had acquired WSL on January 1, 2016.

Fair Value Disclosures [Abstract]
Fair Value	FAIR VALUE Fair value focuses on the estimated price that would be received to sell an asset or paid to transfer a liability, which is referred to as the exit price. Inputs to valuation techniques used to measure fair value fall into three broad levels (Levels 1, 2, and 3) as follows: Level 1 —Observable inputs that reflect quoted prices for identical assets or liabilities in active markets that we have the ability to access at the measurement date. Level 2 —Observable inputs, other than quoted prices included in Level 1, for the asset or liability or prices for similar assets and liabilities. Level 3 —Unobservable inputs reflecting the reporting entity’s estimates of the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk). All marketable securities were valued based on quoted prices for similar assets in active markets or quoted prices for identical or similar assets in markets that are not active (Level 2 in the fair value hierarchy). We measure our marketable securities on a recurring, monthly basis. The fair value of the contingent consideration related to the 2016 acquisition of WSL was $600 at June 30, 2017 . This valuation was based on significant inputs that are not observable in the market, which are referred to as Level 3 inputs. Key assumptions include a probability-adjusted level of earnings before interest, taxes, depreciation, and amortization estimated using the Monte Carlo simulation method. The following table sets forth a reconciliation of changes in the fair value of the contingent consideration: Balance at December 31, 2016 $ 13,500 Change in fair value (1) (12,900 ) Balance at June 30, 2017 $ 600 (1) We recorded an adjustment to the contingent consideration liability in the second quarter of 2017, resulting in an increase in income from operations. The adjustment was caused by a change in the fair value of the contingent liability, which reflected three-year growth targets established by the seller prior to the close of the acquisition. There were no transfers between levels for the periods shown. Fair Value of Other Financial Instruments The recorded value of cash, receivables, and payables approximates fair value. Based on borrowing rates available to us in the applicable year, a fixed-rate debt portfolio with similar terms and maturities would have had a fair value of approximately $443,465 and $683,923 as of June 30, 2017 and December 31, 2016 , respectively.

Marketable Securities	MARKETABLE SECURITIES Our marketable securities have maturities ranging from three to 84 months , but our intent is to hold them for less than one year. They are classified as available for sale and carried at fair value in current assets on the condensed consolidated balance sheets.

Temporary Equity

Temporary Equity Disclosure [Abstract]
Temporary Equity	TEMPORARY EQUITY Prior to our IPO in April 2017, our Class A and Class B Common Stock was considered redeemable under GAAP because of certain repurchase rights granted to our shareholders pursuant to the Schneider National, Inc. Employee Stock Purchase Plan and certain agreements governing ownership of our common stock held by existing shareholders, including members of the Schneider family and their family trusts. As a result, all vested Class A and Class B common shares were recorded as temporary equity (redeemable common shares) on the consolidated balance sheets at their redemption value as of the respective balance sheet dates. Accumulated earnings on the consolidated balance sheets were adjusted for the changes during the period in the current redemption value of vested Class A and Class B redeemable common shares. All contractual redemption features were removed at the time of the IPO. As a consequence, all outstanding shares of Class A and Class B Common Stock ceased to be considered temporary equity and were reclassified to Shareholders’ Equity, including the associated balances of accumulated earnings and accumulated other comprehensive income. As the common shares have no par value, the amounts recorded in temporary equity for the share redemption value were recorded to additional paid-in capital within Shareholders’ Equity upon the transfer. The following table shows all changes to temporary equity during the six months ended June 30, 2017 . Class A Redeemable Common Shares Class B Redeemable Common Shares Accumulated Earnings Accumulated Other Comprehensive Income Shares Amount Shares Amount Total BALANCE—December 31, 2016 83,029,500 $ 563,217 73,294,560 $ 497,175 $ 125,175 $ 883 $ 1,186,450 Net income — — — — 22,569 — 22,569 Other comprehensive income — — — — — 16 16 Dividends declared at $0.05 per share — — — — (7,816 ) — (7,816 ) Change in redemption value of redeemable common shares — 67,254 — 59,369 (126,623 ) — — Transfer from temporary equity to common equity (83,029,500 ) (630,471 ) (73,294,560 ) (556,544 ) (13,305 ) (899 ) (1,201,219 ) BALANCE—June 30, 2017 — $ — — $ — $ — $ — $ —

Equity [Abstract]
Common Equity	COMMON EQUITY All share redemption provisions mentioned in Note 9, Temporary Equity , were removed effective with the IPO of Class B common shares in April 2017. Therefore, all Class A and Class B common shares were reclassified from temporary equity to permanent equity as of April 2017. Prior to the IPO, restricted share awards that were not yet vested and held for more than 180 days were classified as liabilities at their redemption values taking into consideration the portion of the requisite service that had been provided as of the reporting date. At the IPO date, these unvested shares were reclassified to equity. Earnings Per Share As disclosed in Note 1, General , our IPO of shares of Class B Common Stock was effective in April 2017. In connection with the offering, we sold additional shares of common stock.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-based Compensation	SHARE-BASED COMPENSATION In April 2017, we granted various equity-based awards relating to Class B Common Stock under our 2017 Omnibus Incentive Plan. These awards consisted of the following: Number of Shares Subject to Awards Vesting Period in Years Grant Date Fair Value Performance-based restricted shares 307,933 3 $ 19.00 Performance-based restricted stock units 88,268 3 $ 19.00 Restricted shares 76,980 4 $ 19.00 Restricted stock units 169,536 4 $ 19.00 Stock options 229,620 4 $ 6.37 Prior to our IPO, we granted restricted shares of Class B Common Stock ("Pre-IPO Restricted Shares") to certain management employees that vest generally over a three-year period. The Pre-IPO Restricted Shares must be paid out in shares and are accounted for as equity awards. Cash dividends are not paid on the nonvested Pre-IPO Restricted Shares, nor do they accumulate during the vesting period. No new Pre-IPO Restricted Shares were granted in the six months ended June 30, 2017 . We adopted ASU No. 2016-09, Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting , effective January 1, 2017. This guidance simplified several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. We elected to estimate forfeitures of share-based payment awards upfront. The impact of adopting the ASU on our consolidated financial statements was immaterial.

Segment Reporting [Abstract]
Segment Reporting	SEGMENT REPORTING We have three reportable segments – Truckload, Intermodal, and Logistics – which are based primarily on the services each segment provides. The Truckload reportable segment consists of three operating segments (Van Truckload, Specialty Dedicated, and Bulk) that are aggregated because they have similar economic characteristics and meet the other aggregation criteria described in the accounting guidance for segment reporting. Van Truckload delivers truckload quantities over irregular routes using dry van trailers. Specialty Dedicated is similar except that it involves recurring routes between the same locations for which specified trucks are dedicated to the route using specialty trailers. Bulk transports key inputs to the manufacturing process such as specialty chemicals using specialty trailers. The Intermodal reportable segment provides rail intermodal and drayage services to our customers. Company-owned containers and generally Company-owned dray tractors are used to provide these transportation services. The Logistics reportable segment consists of three operating segments (Brokerage, Supply Chain Management, and Import/Export Services) that are aggregated because they have similar economic characteristics and meet the other aggregation criteria described in the accounting guidance for segment reporting. In the Logistics segment, we provide additional sources of truck capacity, manage transportation-systems analysis requirements for individual customers, and provide trans-loading and warehousing services. We generate other revenues from a captive insurance business and from a leasing business which are operated by wholly-owned subsidiaries. We also have operations in Asia that meet the definition of an operating segment. None of these operations meets the quantitative reporting thresholds. As a result, these operations are grouped in “Other” in the tables below. We have also included in “Other” revenues and expenses that are incidental to our activities and are not attributable to any of the reportable segments. Separate balance sheets are not prepared by segment and, as a result, assets are not separately identifiable by segment. All transactions between reporting segments are eliminated in consolidation. The chief operating decision maker reviews revenue for each segment without the inclusion of fuel surcharge revenue. For segment purposes, any fuel surcharge revenues earned are recorded as a reduction of the segment’s fuel expenses. Income from operations at a segment level reflects the measures presented to the chief operating decision maker for each segment. The following tables summarize our segment information. Intersegment revenues were immaterial for all segments, with the exception of Other, which included revenues from insurance premiums charged to other segments for workers’ compensation, auto, and other types of insurance. Intersegment revenues included in Other revenues below were $20,506 and $13,697 for the three months ended June 30, 2017 and 2016 , respectively and $37,379 and $27,894 for the six months ended June 30, 2017 and 2016 , respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business In this report, when we refer to “the Company,” “us,” “we,” “our,” or “ours,” we are referring to Schneider National, Inc. and its subsidiaries. We are a leading transportation services organization headquartered in Green Bay, Wisconsin. We provide a broad portfolio of premier truckload, intermodal, and logistics solutions and operate one of the largest trucking fleets in North America.
Basis of Presentation	Basis of Presentation The accompanying unaudited interim Condensed Consolidated Financial Statements have been prepared in accordance with GAAP and the rules and regulations of the SEC applicable to quarterly reports on Form 10-Q. Therefore, these financial statements and footnotes do not include all disclosures required by GAAP for annual financial statements. These financial statements should be read in conjunction with the Consolidated Financial Statements and related notes included in our Prospectus. Financial results for an interim period are not necessarily indicative of the results for a full year. All intercompany transactions have been eliminated in consolidation. In the opinion of management, these statements reflect all adjustments (consisting only of normal recurring adjustments) necessary for the fair presentation of our financial results for the interim periods presented.
Accounting Standards Issued But Not Yet Adopted	Accounting Standards Issued But Not Yet Adopted In May 2014, the FASB issued ASU 2014-9, Revenue from Contracts with Customers. This guidance outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. As amended, the new revenue recognition standard will be effective for us beginning with the reporting period ending March 31, 2018. The standard permits the use of either the full retrospective or modified retrospective transition method. We are in the process of reviewing and assessing our contracts with customers in accordance with the guidance in the ASU. Based on our analysis to date, we do not expect the adoption of this ASU to have a material impact on our consolidated financial position, results of operations, and cash flows. We plan to use the modified retrospective approach for adoption, which requires us to record the cumulative effect of the transition through retained earnings as of January 1, 2018. We are still evaluating the disclosure requirements of this standard. In January 2016, the FASB issued ASU 2016-1, Financial Instruments–Overall: Recognition and Measurement of Financial Assets and Financial Liabilities . This update was issued to enhance the reporting model for financial instruments regarding certain aspects of recognition, measurement, presentation, and disclosure. These provisions are effective for us beginning with the reporting period ending March 31, 2018. The standard is to be applied using a cumulative-effect adjustment to the balance sheet as of the beginning of the year of adoption. We do not expect the adoption of this ASU to have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-2, Leases , which requires lessees to recognize in the consolidated balance sheets assets and liabilities for leases with lease terms of more than 12 months. Consistent with current accounting principles, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. However, unlike current accounting principles, which require only capital leases to be recognized in the consolidated balance sheets, the new ASU will require both types of leases to be recognized in the consolidated balance sheets. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that companies may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. The transition guidance also provides specific guidance for sale and leaseback transactions, build-to-suit leases, leveraged leases, and amounts previously recognized in accordance with the business combinations guidance for leases. The new standard is effective for us beginning with the reporting period ending March 31, 2019, with early adoption permitted. We currently cannot reasonably estimate the impact that the adoption of this ASU will have on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments , which requires companies to use a forward-looking, expected loss model to estimate credit losses on various types of financial assets and net investments in leases. It also requires additional disclosure related to credit quality of trade and other receivables, including information related to management’s estimate of credit allowances. This guidance is effective for us beginning with the reporting period ending March 31, 2020. We currently cannot reasonably estimate the impact that the adoption of this ASU will have on our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments , which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. Entities must apply the guidance retrospectively to all periods presented but may apply it prospectively if retrospective application would be impracticable. The provisions of this update are effective for us beginning with the reporting period ending March 31, 2018. We currently cannot reasonably estimate the impact that the adoption of this ASU will have on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-4 , Intangibles—Goodwill and Other: Simplifying the Test for Goodwill Impairment, which eliminates Step 2 from the goodwill impairment testing process. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount. Under the new standard, a goodwill impairment loss is measured as the excess of the carrying value of a reporting unit over its fair value. The provisions of this update will be effective for our goodwill impairment test in 2020. We currently cannot reasonably estimate the impact that the adoption of this ASU will have on our consolidated financial statements.
