Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The accompanying condensed consolidated financial statements include the accounts and operations of USA Truck Inc., and present our financial position as of June 30, 2019 and December 31, 2018 and the results of our operations, comprehensive income and cash flows for the three and six months ended June 30, 2019 and 2018. These condensed consolidated financial statements and notes are prepared pursuant to the rules and regulations of the Securities and Exchange Commission for interim reporting and do not include all of the information normally included with financial statements prepared in accordance with generally accepted accounting principles ("GAAP") of the United States. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2018. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates. These condensed consolidated financial statements and notes are unaudited. However, in the opinion of management, these condensed consolidated financial statements reflect all normal recurring adjustments necessary for a fair presentation of the results for the periods presented. Results for interim periods are not necessarily indicative of results to be expected for the full year ending December 31, 2019. The accompanying unaudited condensed consolidated financial statements include USA Truck Inc., and its wholly owned subsidiaries: International Freight Services, Inc. ("IFS"), a Delaware corporation; Davis Transfer Company Inc., a Georgia corporation ("DTC"), Davis Transfer Logistics Inc., a Georgia corporation ("DTL"), and B & G Leasing, L.L.C., a Georgia limited liability company, ("B & G," and collectively with DTC and DTL, "Davis Transfer Company"). References in this report to "it," "we," "us," "our," or the "Company," and similar expressions refer to USA Truck Inc. and its subsidiaries. All significant intercompany balances and transactions have been eliminated in preparing the consolidated financial statements. Certain amounts reported in prior periods have been reclassified to conform to the current year presentation.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	NEW ACCOUNTING PRONOUNCEMENTS In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842) ("ASU 2016-02"), which required lessees to recognize a right-to-use ("ROU") asset and a lease obligation for all leases. Lessees are permitted to make an accounting policy election to not recognize an asset and liability for leases with a term of twelve months or less. Lessor accounting under the new standard is substantially unchanged. Additional qualitative and quantitative disclosures, including significant judgments made by management, are required. The Company adopted the new standard beginning with the first quarter of 2019 using a modified retrospective transition approach, which included a number of practical expedients. The effect of the adoption is reflected within the condensed consolidated financial statements

Revenue Recognition

Revenue Recognition [Abstract]
Revenue Recognition	REVENUE RECOGNITIONRevenue is measured based upon consideration specified in a contract with a customer. The Company recognizes revenue over time, as contractual performance obligations are satisfied by transferring the benefit of the service to our customer. The benefit is transferred to the customer as the service is provided and revenue is recognized accordingly via time-based metrics. A corresponding contract asset of $1.8 million and $1.1 million was recorded in the June 30, 2019 and December 31, 2018 balance sheets, respectively, in the Accounts receivable line item. The Company is entitled to receive payment as it satisfies performance obligations with customers. The amount of remaining performance obligations relating to loads in process at 11:59 pm as of the end of each reporting period was deemed to be immaterial. Our business consists of two reportable segments, Trucking and USAT Logistics (see Note 4 - Segment Reporting). The following tables set forth revenue disaggregated by revenue type and segment: Three Months Ended June 30, Revenue type 2019 2018 Trucking USAT Eliminations Total Trucking USAT Eliminations Total (in thousands) Freight $ 82,664 $ 34,698 $ (2,209) $ 115,153 $ 73,029 $ 45,371 $ (851) $ 117,549 Fuel surcharge 13,034 4,087 (220) 16,901 12,135 4,208 (69) 16,274 Accessorial 778 790 — 1,568 521 1,037 — 1,558 Total $ 96,476 $ 39,575 $ (2,429) $ 133,622 $ 85,685 $ 50,616 $ (920) $ 135,381 Six Months Ended June 30, Revenue type 2019 2018 Trucking USAT Eliminations Total Trucking USAT Eliminations Total (in thousands) Freight $ 164,086 $ 71,328 $ (4,420) $ 230,994 $ 139,934 $ 86,308 $ (1,411) $ 224,831 Fuel surcharge 24,799 7,929 (387) 32,341 23,322 7,803 (117) 31,008 Accessorial 2,493 1,768 — 4,261 1,275 3,280 — 4,555 Total $ 191,378 $ 81,025 $ (4,807) $ 267,596 $ 164,531 $ 97,391 $ (1,528) $ 260,394

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	SEGMENT REPORTING The Company's two reportable segments are Trucking and USAT Logistics. In determining its reportable segments, the Company's chief operating decision maker focuses on financial information, such as operating revenue, operating expense categories, operating ratios and operating income, as well as on key operating statistics, to make operating decisions. Trucking . Trucking is comprised of one-way truckload and dedicated freight motor carrier services. Truckload provides motor carrier services as a medium-haul common and contract carrier. USA Truck has provided truckload motor carrier services since its inception, and continues to derive the largest portion of its gross revenue from these services. Dedicated freight provides truckload motor carrier services to specific customers for movement of freight over particular routes at specified times. USAT Logistics. USAT Logistics' service offerings consist of freight brokerage, logistics, and rail intermodal services. Each of these service offerings match customer shipments with available equipment of authorized third-party motor carriers and other service providers. The Company provides these services to many existing Trucking customers, many of whom prefer to rely on a single service provider, or a small group of service providers, to provide all their transportation solutions. Revenue equipment assets are not allocated to USAT Logistics as freight services for customers are brokered through arrangements with third-party motor carriers who utilize their own equipment. To the extent rail intermodal or other USAT Logistics operations require the use of Company-owned assets, they are obtained from the Company's Trucking segment on an as-needed basis. Depreciation and amortization expense is allocated to USAT Logistics based on the Company-owned assets specifically utilized to generate USAT Logistics revenue. All intercompany transactions between segments reflect rates similar to those that would be negotiated with independent third parties. All other expenses for USAT Logistics are specifically identifiable direct costs or are allocated to USAT Logistics based on relevant cost drivers, as determined by management. A summary of operating revenue by segment is as follows: Three Months Ended Six Months Ended Operating revenue 2019 2018 2019 2018 (in thousands) Trucking revenue (1) $ 96,476 $ 85,685 $ 191,378 $ 164,531 Trucking intersegment eliminations (407) (116) (769) (229) Trucking operating revenue 96,069 85,569 190,609 164,302 USAT Logistics revenue 39,575 50,616 81,025 97,391 USAT Logistics intersegment eliminations (2,022) (804) (4,038) (1,299) USAT Logistics operating revenue 37,553 49,812 76,987 96,092 Total operating revenue $ 133,622 $ 135,381 $ 267,596 $ 260,394 (1) Includes foreign revenue of $9.4 million and $11.0 million for the three months ended June 30, 2019 and 2018, respectively, and $19.0 million and $20.9 million for the six months ended June 30, 2019 and 2018, respectively.

The First Amendment to the Incentive Plan was adopted in May 2017, which, among other things, increased the number of shares of common stock available for issuance under the Incentive Plan by an additional 500,000 shares. The Second Amendment to the Incentive Plan was adopted in May 2019, which, among other things, increased the number of shares of common stock available for issuance under the Incentive Plan by an additional 500,000 shares.

Leases [Abstract]
Leases and Right of Use Assets	LEASES AND RIGHT OF USE ASSETS The Company adopted ASU 2016-02 on January 1, 2019. The standard requires lessees to recognize a ROU asset and lease liability for all leases. Some of our leases contain both lease and non-lease components, which we have elected to treat as a single lease component. We have also elected not to recognize in our consolidated balance sheets leases that have an original lease term, including reasonably certain renewal or purchase options, of twelve months or less for all classes of underlying assets. Lease costs for short-term leases are recognized on a straight-line basis over the lease term. We elected the package of transition practical expedients for existing contracts, which allowed us to carry forward our historical assessments of whether contracts are or contain leases, lease classification and determination of initial direct costs. The Company leases property and equipment under finance and operating leases. The Company has operating and finance leases for revenue equipment, real estate, information technology equipment (primarily servers and copiers), and various other equipment used in operating our business. Certain leases for revenue equipment and information technology include options to purchase or extend, guarantee residual values, or early termination rights. Determining the lease term and amount of lease payments to include in the calculation of the ROU asset and lease liability for leases containing options requires the use of judgment to determine whether the exercise of an option or feature is reasonably certain, and if the optional period and payments should be included in the calculation of the associated ROU asset and liability. In making this determination, we consider all relevant economic factors that would compel us to exercise or not exercise an option or feature. When available, we use the rate implicit in the lease to discount lease payments; however, the rate implicit in the lease is not readily determinable for all of our leases. In such cases, we use an estimate of our incremental borrowing rate to discount lease payments based on information available at lease commencement. As of June 30, 2019, the Company has entered into leases with lessors who do not participate in the Credit Facility. Currently, such leases do not contain cross-default provisions with the Credit Facility. Revenue Equipment In addition to the revenue equipment owned by the Company, we currently lease 1,012 tractors and 810 trailers. Of the leased revenue equipment, 664 tractors and 761 trailers are classified as finance leases and 348 tractors and 49 trailers are classified as operating leases. Some of these assets are leased on a month-to-month basis and the leases can be terminated without penalty. The lease term for these types of leases is determined by the length of the underlying customer contract or based on the judgment of management. These leases are treated as short-term as the cumulative ROU is less than 12 months over the term of the contract. The Company uses the leased revenue equipment for the same operational purposes as its owned equipment. Real Estate We have operating and finance leases for office space, terminal facilities, and drop yards. Many of our leases contain charges for common area maintenance or other miscellaneous expenses that are updated based on landlord estimates. Due to this variability, the cash flows associated with these charges are not included in the minimum lease payments used in determining the ROU asset and associated lease liability. Some of our real estate leases contain options to renew or extend the lease or terminate the lease before the expiration date. These options are factored into the determination of the lease term and lease payments when their exercise is considered to be reasonably certain. Information Technology and Other Equipment The Company leases information technology and other equipment, primarily servers and copiers, in the course of our operations. The components of lease expense for the three and six months ended June 30, 2019 are as follows: Three Months Ended Six Months Ended June 30, 2019 June 30, 2019 (in thousands) Operating lease costs $ 2,356 $ 4,515 Finance lease costs: Amortization of assets 2,959 5,650 Interest on lease liabilities 603 1,149 Total finance lease costs 3,562 6,799 Variable and short-term lease costs 212 773 Total lease costs $ 6,130 $ 12,087 Supplemental information and balance sheet location related to leases is as follows: Operating leases: June 30, 2019 (in thousands) Operating lease right-of-use assets $ 13,574 Current operating lease obligations 7,578 Long-term operating lease obligations 6,037 Total operating lease liabilities $ 13,615 Finance leases: Property, plant and equipment, at cost 102,074 Accumulated amortization (21,913) Property, plant and equipment, net $ 80,161 Current finance lease obligations 21,665 Long-term finance lease obligations 59,012 $ 80,677 Weighted average remaining lease term: (in months) Operating leases 42 months Finance leases 45 months Weighted average discount rate: Operating leases 3.87 % Finance leases 3.41 % Supplemental cash flow information related to leases is as follows: Cash paid for amounts included in measurement of liabilities: June 30, 2019 (in thousands) Operating cash flows from operating leases $ 3,885 Operating cash flows from finance leases 603 Financing cash flows from finance leases 6,202 ROU assets obtained in exchange for lease liabilities: Operating leases 931 Finance leases 16,303 Maturities of lease liabilities as of June 30, 2019 are as follows: Finance Leases Operating Leases (in thousands) 2019 (remaining) $ 13,617 $ 3,667 2020 25,393 5,911 2021 9,959 1,575 2022 9,959 1,010 2023 20,817 706 Thereafter 8,110 1,394 Total lease payments 87,855 14,263 Less: Imputed interest (7,178) (648) Total lease obligations 80,677 13,615 Less: Current obligations (21,665) (7,578) Long-term lease obligations $ 59,012 $ 6,037 OTHER COMMITMENTS As of June 30, 2019, the Company had $26.1 million in noncancellable commitments for purchases of revenue equipment. We anticipate funding these commitments with cash flows from operating and financing activities. RELATED PARTY LEASE In the normal course of business, the Company leases office and shop space from a related party under a monthly operating lease. Rent expense for this space was approximately $0.04 million and $0.08 million for the three and six months ended June 30, 2019. This expense is included in the "Operations and maintenance" line item in the accompanying consolidated statement of income and comprehensive income. SALE-LEASEBACK TRANSACTION five

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES During the three months ended June 30, 2019 and 2018, the Company's effective tax rate was 99.5% and 24.4%, respectively. During the six months ended June 30, 2019 and 2018, the Company's effective tax rate was 33.5% and 25.7%, respectively. The Company's effective tax rate, when compared to the federal statutory rate of 21%, is primarily affected by state income taxes, net of federal income tax effect for the current year periods, and permanent differences, the most significant of which is the effect of the partially non-deductible per diem pay structure for our drivers. Drivers may elect to receive non-taxable per diem pay in lieu of a portion of their taxable wages. This per diem program increases the Company's drivers' net pay per mile, after taxes, while decreasing gross pay, before taxes. Per diem pay is partially non-deductible by the Company under current IRS regulations. As a result, salaries, wages and employee benefits costs are slightly lower and effective income tax rates are higher than the statutory rate. Due to the partially non-deductible effect of per diem pay, the Company's tax rate will change based on fluctuations in earnings (losses) and in the number of drivers who elect to receive this pay structure. Generally, as pretax income or loss increases, the impact of the driver per diem program on the Company's effective tax rate decreases, because aggregate per diem pay becomes smaller in relation to pretax income or loss, while in periods where earnings are at or near breakeven the impact of the per diem program on the Company's effective tax rate can be significant. Additionally, during the current period the Company's tax rate was negatively affected by vesting of equity-based compensation at a lower stock price than the price at which it was granted, resulting in an increase to tax expense and the effective tax rate.

Accounting Changes and Error Corrections [Abstract]
Correction of Immaterial Errors	CORRECTION OF IMMATERIAL ERRORS In connection with the preparation of our condensed consolidated financial statements for the three months ended March 31, 2019, we identified immaterial errors related to the recognition of certain income and expenses in the prior quarterly and annual periods. In accordance with U.S. Securities and Exchange Commission Staff Accounting Bulletin ("SAB") No. 99, "Materiality," and SAB No. 108, "Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements," we evaluated the errors and determined that the related impact was not material to our financial statements for any prior annual or interim period, but that correcting the cumulative impact of the error would be significant to our results of operations for the three months ended March 31, 2019. Accordingly, we have adjusted our condensed consolidated balance sheet at December 31, 2018. The impact of the errors on the Company's three months ended March 31, 2018 condensed consolidated statements of income and comprehensive income, consolidated statement of cash flows, and retained earnings were deemed to be immaterial and will be adjusted in conjunction with our annual report on Form 10-K for the year ended December 31, 2019. We will also correct previously reported financial information for such immaterial errors in our future filings, as applicable. The effects of the adjustment on the individual line items within our condensed consolidated balance sheet at December 31, 2018 are as follows: December 31, 2018 As Reported Adjustments As Adjusted (in thousands) Accounts receivable, net $ 56,003 $ 1,186 $ 57,189 Other receivables 5,104 584 5,688 Prepaid expenses and other current assets 7,224 451 7,675 Accounts payable 22,453 1,029 23,482 Accrued expenses 8,977 389 9,366 Retained earnings 77,664 803 78,467 Total stockholders' equity 80,470 803 81,273

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842) ("ASU 2016-02"), which required lessees to recognize a right-to-use ("ROU") asset and a lease obligation for all leases. Lessees are permitted to make an accounting policy election to not recognize an asset and liability for leases with a term of twelve months or less. Lessor accounting under the new standard is substantially unchanged. Additional qualitative and quantitative disclosures, including significant judgments made by management, are required. The Company adopted the new standard beginning with the first quarter of 2019 using a modified retrospective transition approach, which included a number of practical expedients.
