How truck emissions testing works
California truck emissions testing under Clean Truck Check follows a defined sequence: register the vehicle, pay state fees, inspect with a credentialed tester, and verify compliance in CTC-VIS. Here is each step in plain language.
Step 1: Register in CTC-VIS
Confirm your vehicle is in scope—see who needs Clean Truck Check. Create a CTC-VIS account on CARB’s portal, add the VIN, and verify details match your registration documents.
New operators should follow the CTC-VIS registration guide. CARB hosts official instructions on arb.ca.gov.
Fleet teams register acquisitions within days of taking possession—delay creates deadline surprises downstream.
Step 2: Pay CARB compliance fees
CARB assesses a compliance fee per registered vehicle. Industry references often cite $32.13 annually—use that for budgeting but verify the live amount in CTC-VIS before paying. This fee is separate from the inspection invoice you pay your tester ($60–$350 typical on Zurfex).

CTC-VIS displays your testing due window after registration and fee payment—note it on your calendar.
Step 3: Book a credentialed tester
Identify your test type: OBD for most 2007+ engines, opacity for many older diesels. Search Zurfex by ZIP, choose mobile or shop service, and schedule inside your due window—see deadlines.
The tester performs the inspection with CARB-approved equipment and submits results electronically. You receive pass/fail notification through normal booking channels and should confirm status in CTC-VIS.
Failures require repair and retest within CARB timelines—see penalties if retests slip.
Step 4: Stay compliant ongoing
Clean Truck Check repeats each compliance cycle—moving toward more frequent testing for much of the fleet. Use the compliance checklist and what to expect on test day to streamline each cycle.
