Many light-duty fleets do not realize DOT regulations are triggered not only by GVW, but also by gross combination vehicle weight (GCVW) – the combined weight of the vehicle and the trailer. It doesn’t matter if you have a one-truck or a 500-truck fleet, you must be compliant with DOT rules. When the GCVW is 10,001 pounds or more, a vehicle is covered under DOT regs and must display a DOT number or it will be subject to a fine if pulled over by the police.
