California's emissions mandate has real teeth. We test your trucks on-site, get you a passing result, and fix the cause if you fail — so you stay legal and stay running.
The Clean Truck Check applies to nearly every diesel truck over 14,000 lbs that runs on California roads. Testing is required on a recurring schedule — and the penalties for missing it are brutal.
One test today is cheaper than one day parked. Get compliant before the notice — not after.
It's California's heavy-duty vehicle emissions compliance program. If your truck is over 14,000 lbs and runs on California public roads, it almost certainly applies — even if the truck is registered out of state. Testing is required on a recurring schedule, and that schedule is tightening over the next few years.
Bottom line: the cost of a test is nothing next to $10,000 a day in fines or a truck pulled out of service. Stay ahead of it.
Nearly all diesel and alternative-fuel heavy-duty vehicles over 14,000 lbs GVWR operating on California roads.
Fines can reach $10,000 per vehicle per day, and trucks can be put out of service by enforcement.
Yes — and if you fail, we can repair the cause right there and re-test, because we're a full diesel and equipment repair operation, not just a testing station.
