How much is the CARB Clean Truck Check state fee?

CARB charges a compliance fee per registered vehicle, commonly cited at $32.13 annually. Fee amounts are set by regulation and can change—always verify the current fee on arb.ca.gov or in your CTC-VIS account before paying.

How much do credentialed testers charge?

Tester fees are set by the market, not CARB. On Zurfex, many inspections fall in the $60–$350 range depending on test type, location, mobile vs shop service, and fleet volume. Compare quotes before booking.

Are retests included in the tester fee?

Usually not. A failed inspection typically requires repair plus a new paid test appointment. Confirm retest pricing with your tester when booking the initial visit.

Clean Truck Check costs & fees

Budgeting for Clean Truck Check means separating CARB’s state compliance fee from the private-market price of the emissions inspection itself. Together they define your per-truck cost of staying road-legal in California.

CARB state compliance fee

When you register a vehicle in CTC-VIS, CARB assesses a compliance fee tied to program administration and data systems. Industry materials and CARB communications often reference an annual fee of $32.13 per vehicle—a figure you will see in forums, fleet spreadsheets, and compliance webinars.

That number is useful for planning, but it is not a quote. CARB may adjust fees through the regulatory process. Before you pay—or before finance approves a fleet budget—confirm the current amount on arb.ca.gov and in your CTC-VIS payment screen.

The state fee is separate from the inspection invoice you pay a credentialed tester. Both are required for compliance; paying only one does not clear your obligation.

Typical credentialed tester fees

Private testers set their own prices based on equipment investment, drive time, shop overhead, and demand in their service area. Across California markets on Zurfex, single-truck inspections commonly fall between $60 and $350, with most owner-operator bookings landing mid-range for standard OBD or opacity tests.

Mobile testing—where a credentialed technician comes to your yard, terminal, or job site—often carries a modest premium versus driving to a fixed shop. For fleets, that premium can still be cheaper than deadhead miles and driver hours lost to shop queues.

Hidden costs to plan for

Failed tests drive the real budget variance. DPF cleanings, DEF system repairs, opacity-related engine work, and diagnostic labor can exceed the inspection fee by orders of magnitude. Fleets that pre-screen units—checking for dash lamps, excessive smoke, and recent derates—see fewer surprise shop bills.

Retests after repair are another line item. Assume at least one full tester fee per retest unless your provider offers a packaged rate. Non-compliance carries its own cost: registration holds, missed loads, and CARB enforcement penalties.

Fleet managers scheduling dozens of units should explore bulk scheduling for potential volume efficiencies and clearer total cost forecasting.
