Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The condensed consolidated financial statements include the accounts of Covenant Logistics 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 Logistics Group, Inc. and its wholly owned subsidiaries. All 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 that 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, 2025, condensed consolidated balance sheet was derived from our audited balance sheet as of that date. Our operating results are subject to seasonal trends when measured on a quarterly basis; therefore, operating results for the six months ended June 30, 2026 are not necessarily indicative of the results that may be expected for the year ending December 31, 2026. 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, 2025.
Revenue [Policy Text Block]	Revenue Recognition Revenue, drivers' wages, and other direct operating expenses generated by our Expedited and Dedicated reportable segments are recognized proportionally as the transportation service is performed based on the percentage of miles completed as of the period end. Revenue is recognized on a gross basis at amounts charged to our customers because we control and are primarily responsible for the fulfillment of the promised service. Revenue includes transportation revenue, fuel surcharges, loading and unloading activities, equipment detention, and other accessorial services. Revenue generated by our Managed Freight reportable segment is recognized proportionally as the services are provided based on the percentage of completion method using the estimated time elapsed as of the period end. Revenue is recorded on a gross basis, without deducting third-party purchased transportation costs, as we act as a principal with substantial risks as primary obligor. Revenue for the Warehousing reportable segment is generally recognized as the service is performed, based upon a weekly rate. The Company’s contracts with customers generally have original expected durations less than one year. Accordingly, the Company has elected the practical expedient to not disclose information about remaining unsatisfied performance obligations.
Property, Plant, and Equipment [Policy Text Block]	Property and Equipment Property and equipment is stated at cost less accumulated depreciation. Depreciation for book purposes is determined using the straight-line method over the estimated useful lives of the assets. Depreciation of revenue equipment is our largest item of depreciation. We generally depreciate new tractors over five years to salvage values ranging from approximately 0% to 35% of their cost, depending on the reportable segment profile of the equipment. We generally depreciate new trailers over seven years for refrigerated trailers and ten years for dry van trailers to salvage values of approximately 20% and 25% of their cost, respectively. We annually, or whenever events or changes in circumstances indicate that a review is warranted, review the reasonableness of our estimates regarding useful lives and salvage values of our revenue equipment and other long-lived assets, based upon, among other things, our experience with similar assets, conditions in the used revenue equipment market, and prevailing industry practice.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements Accounting standards not yet adopted In September 2025, the Financial Accounting Standards Board ("FASB") issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software: Targeted Improvements to the Accounting for Internal-Use Software, which clarifies and modernizes the accounting for costs related to internal-use software. The amendments in the standard remove all previous references to project stages and clarify the threshold entities apply to begin capitalizing costs. The standard becomes effective for us on January 1, 2028, for annual and interim periods and may be adopted on a prospective basis, a modified basis for in-process projects, or a retrospective basis. The Company is currently evaluating the effects adoption of this guidance will have on our consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses which was later clarified by ASU 2025-01. This guidance requires disclosure of disaggregated information about certain income statement expense line items in the notes to the financial statements. The guidance in this ASU is effective for all public entities for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. The update may be applied either prospectively or retrospectively. Early adoption is permitted. The Company is currently evaluating the effects adoption of this guidance will have on our consolidated financial statements. Accounting standards adopted In July 2025, the FASB issued ASU 2025-05, Measurement of Credit Losses for Accounts Receivable and Contract Assets. In developing reasonable and supportable forecasts as part of estimating expected credit losses, all entities may elect a practical expedient that assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset. This guidance became effective for us for our annual reporting period beginning January 1, 2026, and related interim reporting periods. We made the election to adopt the practical expedient as of January 1, 2026. The adoption of this standard had an immaterial effect on our consolidated financial statements.
