Frequently Asked Questions about HD I/M Testing
Frequently Asked Questions about HD I/M Testing
How often do I need a Clean Truck Check?
Answer: As of 2024, most vehicles need testing twice a year. Starting 2025, this may increase to four times a year. We help you track these deadlines.
What vehicles are subject to the Clean Truck Check?
Answer: Nearly all non-gasoline vehicles with a Gross Vehicle Weight Rating (GVWR) over 14,000 lbs operating in California. This includes diesel trucks, buses, and RVs.
What happens if my truck fails the OBD test?
Answer: If you have an active Check Engine Light or uncleared codes, you will fail. We provide a diagnostic report so you can fix the issue. Once repaired, we can re-test your vehicle to clear the DMV block.
What is the difference between PSIP and the new HD I/M program?
Answer: The HD I/M (Clean Truck Check) program effectively replaces the older PSIP opacity rules for most vehicles, requiring more frequent, electronic reporting via OBD systems.
