Why Choose Us?

• We provide mobile smog testing on 2013 and newer vehicles.

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.
