Why Mobile Testing Is Required

CARB enforcement actions are increasing across the Bay Area, particularly around the Port of San Francisco and South SF industrial sectors. Fleets are facing DMV holds and financial penalties if they do not complete Clean Truck Check testing by their required deadline.

Our mobile service eliminates the need for trucks to be driven to a shop or removed from service. Testing typically takes less than 20 minutes per truck.
