Which Trucks Are Exempt from CARB Testing

Certain vehicles are exempt from the California CARB Clean Truck Check program. Exemptions may apply to light-duty vehicles under 14,000 lbs GVWR, new trucks with active manufacturer warranties, or vehicles that operate exclusively outside of California. Some specialized equipment, emergency vehicles, and low-use agricultural trucks may also qualify. Understanding whether your vehicle is exempt can save time and prevent unnecessary testing.
