Clean Truck Check Program

California HD I/M emissions testing for medium- and heavy-duty diesel trucks

At Auto Tech Smog & Repair, we are licensed to perform Clean Truck Check emissions testing for diesel trucks. California requires periodic emissions inspections for medium- and heavy-duty trucks to ensure cleaner air and better performance.

HD I/M Program

We offer California’s Heavy-Duty Vehicle Inspection and Maintenance (HD I/M) program - a regulation by the California Air Resources Board (CARB) that ensures heavy-duty vehicle emissions control systems function properly through periodic testing.

Eligible vehicles: Diesel trucks from 2013 or newer with a gross vehicle weight rating of 14,000 lbs or more.
