Frequently Asked Questions

What is a Clean Truck Check?

California's Heavy-Duty Inspection & Maintenance (HD I/M) program requires emissions testing for all diesel, alternative-fuel, and hybrid vehicles over 14,000 lbs GVWR operating on California roads. This applies even if your truck is registered out of state. Testing is required twice per year (every 6 months). Failing to comply can result in penalties up to $1,000 per vehicle.

How often do I need a Clean Truck Check?

California requires testing every 6 months (twice per year). RVs and agricultural vehicles need testing once per year. We offer scheduled recurring visits so you never miss a deadline.

What happens if my truck fails?

We'll explain exactly what needs to be fixed. Once repairs are made, we'll come back for a re-test. Our pre-check inspection can help you avoid failed tests in the first place. Contact us about our re-test policy.
