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.

At OC Clean Truck, we uphold the highest standards of operation. As competition intensifies, we are seeing people from outside the industry entering into the program. Our observations indicate that they are conducting  inspections with inadequate licensing and insurance coverage, thereby jeopardizing their customers to liability. We take pride in our numerous advantages over competitors.
