Clean Truck Check (formerly the Heavy-Duty Inspection and Maintenance program)
It affects 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. 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.
Key Events and Estimated Implementation Dates Are:
- CARB plans to implement a three-month reporting season projected to run from October 1, 2023, to December 31, 2023.
- By December 31, 2023, vehicle owners need to complete the registration of their vehicles in the Clean Truck Check database and pay a $30 per vehicle 2023 annual compliance fee.
- CARB estimates that periodic testing requirements will become effective starting in July 2024. This means that a passing compliance test would be required to be submitted to CARB for all vehicle compliance deadlines on or after July 1, 2024.
