Become a Clean Truck Check tester on Zurfex

California’s HD I/M program created sustained demand for credentialed emissions inspectors. Zurfex gives independent testers and small shops a booking channel—without building custom software—to reach owner-operators and fleets searching by ZIP code.

Why testers choose Zurfex

Clean Truck Check is not a one-year fad. CARB is expanding testing frequency for much of the fleet, which means recurring appointments per VIN rather than occasional walk-ins. Marketplaces that aggregate demand help smooth seasonality around CTC-VIS deadline clusters.

Zurfex handles discovery, scheduling, and payments so you focus on inspections. Set your service radius, offer mobile or shop-based visits, and build reputation through verified reviews from truck owners.

CARB defines credentialing rules and audit standards on arb.ca.gov—Zurfex does not substitute for official tester training or equipment certification.
