This bill amends federal law to establish specific regulations for heavy-duty tow and recovery vehicles. It defines a covered heavy-duty tow and recovery vehicle as one transporting a wrecked or disabled vehicle to the nearest appropriate repair facility or other agency-directed location. The legislation prohibits states from imposing overall length limits on vehicle combinations, or the length of individual vehicles, when transported by these tow vehicles, provided the original disabled vehicle combination complied with applicable length limits at the time of the incident. Furthermore, states cannot limit the number of vehicles transported in such combinations under the same compliance condition. The bill also stipulates that these operations must occur within a single state and that the vehicle's axle weights and configuration must safely operate on highway bridges, as determined by the transportation agency of jurisdiction.
