Accounting Policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

In the opinion of the management of USA Truck, Inc., the accompanying unaudited condensedconsolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information. Certain information and footnote disclosures normally included in financial statements required by GAAP have been condensed or omitted. All normal recurring adjustments considered necessary for a fair presentation have been included. Operating results for the three and nine month periods ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. These financial statements should be read in conjunction with the financial statements, and footnotes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.

Certain previously reported amounts have been reclassified to conform to the current year presentation. Additionally, financial statements and notes to the financial statements previously reported in prior periods have been recast to reflect the change in accounting principle for tires. Refer to note 10 of the footnotes to the Company’s condensed consolidated financial statements for further discussion regarding the change in accounting principle.

Accounting Changes [Policy Text Block]

During the third quarter of 2015, the Company changed its accounting policy for tires. Prior to this change, the cost of the replacement tires placed in service was reported as prepaid tires and amortized based on estimated usage of the tires. Under the new policy, the cost of tires mounted on purchased revenue equipment is capitalized as part of the total equipment cost and is depreciated over the useful life of the related equipment. Subsequent replacement tires are expensed at the time those tires are placed in service. Management believes this new policy is preferable under the circumstances because it provides a more precise method for recognizing expenses related to tires consistent with industry practice. Comparative financial statements for all prior periods have been adjusted (recast) to apply the new policy retrospectively, and are reflected under columns marked “Recast”.

New Accounting Pronouncements, Policy [Policy Text Block]

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09,

Revenue from Contracts with Customers

(“ASU 2014-09”), which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to implement this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. The standard is effective for annual periods beginning after December 15, 2016, and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). In July 2015, the FASB approved the delayed effectiveness of ASU 2014-09 for one year. Management is currently evaluating the impact of the pending adoption of ASU 2014-09 on the Company’s condensed consolidated financial statements and has not yet determined the method by which the Company will adopt the standard in its 2018 fiscal year.
