What is the CTC-VIS website URL?

Access the Clean Truck Check Vehicle Inspection System at cleantruckcheck.arb.ca.gov. Bookmark it and link from your fleet compliance SOP—this is where due dates and pass/fail status live.

Who should create the CTC-VIS account?

The registered owner or an authorized fleet compliance manager should create the account. Ensure login credentials are shared with whoever monitors due windows—CTC-VIS is the system of record, not your TMS or ELD portal.

Can I register multiple VINs under one account?

Yes. Fleet operators typically register every qualifying heavy-duty unit under a single organization account, then manage each VIN’s fees and testing schedule individually within CTC-VIS.

CTC-VIS registration walkthrough

CTC-VIS (Clean Truck Check Vehicle Inspection System) is CARB’s online portal for registering trucks, paying state compliance fees, viewing testing due dates, and confirming pass/fail results. Every owner-operator and fleet manager should know how to navigate it.

Step 1: Create your account

Visit cleantruckcheck.arb.ca.gov and follow CARB’s account creation flow. Use a business email your compliance team monitors—not a driver’s personal address that may change when turnover occurs. CARB publishes screen-by-screen help on arb.ca.gov if the portal layout updates.

Step 2: Add vehicles by VIN

Register each qualifying heavy-duty diesel unit using its 17-character VIN. Double-check digits—transposed characters are a common source of mismatched compliance records. For fleets onboarding used equipment, verify the prior owner removed or transferred the unit correctly to avoid duplicate registrations.

CTC-VIS assigns a compliance cycle and testing window after registration. Newly added trucks may show immediate fee payment prompts; handle those before scheduling your credentialed test.

Step 3: Pay the state compliance fee

CARB assesses a compliance fee per registered vehicle—industry materials often cite $32.13 annually. Fee amounts are set by regulation and can change; always confirm the figure on your CTC-VIS payment screen and on arb.ca.gov before budgeting fleet-wide.

Paying the fee registers your program obligation but does not replace the emissions inspection. You need both current fee status and a passing test within your due window for compliant status.

Step 4: Read your due date & test type

Each VIN displays its testing window and required method (OBD or smoke opacity). Schedule with a CARB credentialed tester during the open window—not months early unless CARB guidance allows it. See our 2026 deadline calendar for program-wide phase-in context and tips on finding VIN-specific dates in CTC-VIS.

Step 5: Book testing & verify results

Search credentialed testers on Zurfex and book mobile or shop service. After the inspection, the tester submits results electronically to CARB. Return to CTC-VIS within a few days to confirm the pass appears before dispatching the truck.
