The most significant estimates that affect our financial statements include the accrued liabilities for insurance and claims and useful lives and salvage values of property and equipment.

If based on that review, changes in circumstances indicate that the carrying amount of such assets may not be recoverable, we evaluate recoverability by comparing the undiscounted cash flows associated with the asset to the asset's carrying amount. We also evaluate the remaining useful lives of intangible assets to determine if events or trends warrant a revision to the remaining period of amortization. An impairment loss would be recognized if the carrying amount of the long-lived asset or intangible asset is not recoverable and the carrying amount exceeds its fair value. For long-lived assets classified as held and used, the carrying amount is not recoverable when the carrying value of the long-lived asset exceeds the sum of the future net cash flows. We do not separately identify assets by operating segment because tractors and trailers are routinely transferred from one operating fleet to another. As a result, none of our long-lived assets have identifiable cash flows from use that are largely independent of the cash flows of other assets and liabilities. Thus, the asset group used to assess impairment would include all of our assets. No impairment charges were recorded during the years ended December 31, 2023, 2022, and 2021.</span></div>
