Soto Mobile Clean Truck Check (CARB) Testing

Soto Mobile Clean Truck Check testing is a mobile emissions testing service for California’s Clean Truck Check program run by the California Air Resources Board. It provides on-site CARB-compliant emissions testing for diesel, alternative fuel, and hybrid vehicles over 14,000 lbs GVWR that operate in California. Services include OBD testing for 2013 and newer model year diesel engines using CARB-certified OBD test devices, and opacity smoke testing plus visual inspections for 2012 and older engines. The service comes to your location to test trucks, semi-trucks, pickup trucks, motorhomes, and RVs, with same-day and next-day appointments available. Vehicle owners use these credentialed testers to meet Clean Truck Check requirements by submitting a passing emissions test to CARB before the vehicle’s compliance deadline to avoid DMV registration holds and penalties.
