Basis of Presentation and Accounting Pronouncements [Abstract] |
Basis of Presentation and Significant Accounting Policies [Text Block] | Basis of Presentation and New Accounting Pronouncements Heartland Express, Inc. is a holding company incorporated in Nevada, which directly or indirectly owns all of the stock of the following active legal entities: Heartland Express, Inc. of Iowa, Heartland Express Services, Inc., Heartland Express Maintenance Services, Inc. ("Heartland Express"), and Midwest Holding Group, LLC and Millis Transfer, LLC ("Millis Transfer"), and Smith Transport, LLC ("Smith Transport"), and CFI entities, Transportation Resources, Inc. and Contract Freighters, Inc. (collectively with certain Mexican entities, "CFI"). Effective December 31, 2024, Franklin Logistics, LLC was merged into Smith Transport, LLC. We, together with our subsidiaries, are a short, medium, and long-haul truckload carrier and transportation services provider. We primarily provide nationwide asset-based dry van truckload service for major shippers across the United States, along with cross-border freight and other transportation services offered through third party partnerships in Mexico. The accompanying consolidated financial statements include the parent company, Heartland Express, Inc., and its subsidiaries, all of which are wholly owned. All material intercompany items and transactions have been eliminated in consolidation. The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and notes to the financial statements required by U.S. GAAP for complete financial statements. In the opinion of management, all normal, recurring adjustments considered necessary for a fair presentation have been included. The consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2024 included in the Annual Report on Form 10-K the Company filed with the Securities and Exchange Commission (the "SEC") on February 18, 2025. Interim results of operations are not necessarily indicative of the results to be expected for the full year or any other interim periods. There were no changes to the Company's significant accounting policies during the three months ended March 31, 2025. In December 2023, the FASB issued Update 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures". The amendments in the update improve income tax disclosures primarily related to the rate reconciliation and income taxes paid information as well as the effectiveness of certain other income tax disclosures. The new standard is effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of adopting this new standard although based on initial evaluation we do not believe there will be a material impact from adoption.
