What is Clean Truck Check?

Clean Truck Check is California’s periodic emissions inspection program for many heavy-duty diesel vehicles over 14,000 lbs GVWR. Use this ZIP search to find nearby testers. After you pass, CTC-VIS filing is a separate step — we do not issue the official certificate. Source: Clean Truck Check overview (https://ww2.arb.ca.gov/clean-truck-check-overview-fact-sheet).

Who needs a CARB emissions test?

Most heavy-duty diesel vehicles over 14,000 lbs GVWR that operate in California must participate in Clean Truck Check. Exact coverage depends on vehicle type, weight, and use. Search testers by ZIP here to book an inspection near you. Source: Clean Truck Check overview (https://ww2.arb.ca.gov/clean-truck-check-overview-fact-sheet).

How much does a CARB emissions test cost?

Testing fees vary by tester, location, and vehicle. Compare nearby listings to see options that fit your schedule and budget. Pricing is set by each testing provider, not by CARB Test Finder.

How long does CARB testing take?

Most Clean Truck Check inspections take about 20 to 45 minutes, depending on the vehicle and site. Arrive with required documents and allow extra time for paperwork. After you pass, certificate filing stays on our CARB certification page.

What if my truck fails the emissions test?

Ask the tester which items failed and what is needed for a retest. Complete repairs, then book a retest with a listed provider. CARB Test Finder helps you find testers; repairs are handled by those businesses.

How often do I need Clean Truck Check testing?

Frequency depends on your vehicle and current CARB rules. Many covered vehicles need testing twice each year. Confirm your cycle with a verified tester, and use ZIP search to find California CARB testing locations near you. Source: Clean Truck Check FAQ (https://ww2.arb.ca.gov/resources/fact-sheets/clean-truck-check-faq-0).

Is CARB Test Finder affiliated with the California Air Resources Board?

No. CARB Test Finder is an independent marketplace operated by Cobalt Axis LLC. We help owners find emissions testers and start CTC-VIS filing support after a passing test. We are not CARB.gov and do not issue the official compliance certificate.

Can I reschedule my testing appointment?

Yes. Most listed testers let you reschedule directly with them before your appointment. Check the tester profile or confirmation for their policy, or search again by ZIP if you need a new slot.
