Significant Accounting Policies [Text Block] | Note 1. Significant Accounting Policies Basis of Presentation The condensed consolidated financial statements include the accounts of Covenant Transportation Group, Inc., a Nevada holding company, and its wholly-owned subsidiaries. References in this report to "we," "us," "our," the "Company," and similar expressions refer to Covenant Transportation Group, Inc. and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X promulgated under the Securities Act of 1933. In preparing financial statements, it is necessary for management to make assumptions and estimates affecting the amounts reported in the condensed consolidated financial statements and related notes. These estimates and assumptions are developed based upon all information available. Actual results could differ from estimated amounts. In the opinion of management, the accompanying financial statements include all adjustments which are necessary for a fair presentation of the results for the interim periods presented, such adjustments being of a normal recurring nature. Certain information and footnote disclosures have been condensed or omitted pursuant to such rules and regulations. The December 31, 2012 condensed consolidated balance sheet was derived from our audited balance sheet as of that date. These condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto included in our Form 10-K for the year ended December 31, 2012. Results of operations in interim periods are not necessarily indicative of results to be expected for a full year. Recent Accounting Pronouncements Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income–In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2013-02 ("ASU 2013-02"). Under ASU 2013-02, an entity is required to provide information about the amounts reclassified out of accumulated other comprehensive income ("AOCI") by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. ASU 2013-02 did not change the requirements for reporting net income or other comprehensive income in the financial statements. We adopted this guidance on January 1, 2013. This accounting guidance only impacted presentation and did not have an impact on our condensed consolidated balance sheets, results of operations, comprehensive income (loss), stockholders' equity or cash flows. Refer to Note 11.
