CARB Clean Truck Check
CARB Compliance Update: Fleets with 14,000lb GVWR Diesels no longer have to test their vehicle emission system between July – December 2024, but owners are required to pay the 2024 compliance fee during the periodic testing window. Testing will begin in January 2025.
Clean Truck Check (formerly the Heavy-Duty Inspection and Maintenance program)
The goal of Clean Truck Check is to ensure that heavy-duty vehicles operating in California remain equipped with properly functioning emissions controls, and when malfunctioning, that these components are repaired in a timely manner. Clean Truck Check requires reporting, vehicle testing, and compliance fees.
CARB Compliance requirements affect non-gasoline vehicles with a gross vehicle weight rating (GVWR) greater than 14,000 pounds operating in California. Clean Truck Check is similar to California’s Smog Check program for light-duty vehicles.
