Mobile Clean Truck Check

 Clean Truck Check applies to almost all diesel,  alternative fuel, and hybrid vehicles, with a GVWR over 14,000 pounds  operating on public roads and highways in California even if they are  not registered in California. This includes government vehicles;  motorcoaches; transit, shuttle and school buses; hybrid vehicles;  commercial and personal use vehicles; California registered motorhomes;  and single vehicle fleets. DMV registration holds will apply to vehicles  that do not meet Clean Truck Check requirements.
