Mobile truck emissions testing
Why deadhead a tractor across town when a CARB credentialed tester can plug in at your yard? Mobile Clean Truck Check inspections bring OBD and opacity equipment to terminals, construction sites, and owner-operator parking—keeping compliance aligned with real fleet workflows.
How mobile inspections work
You book a credentialed tester through Zurfex, confirm your address and unit count, and the inspector arrives with CARB-approved gear. For OBD tests, they connect to the diagnostic port, verify readiness and fault status, and transmit results. For opacity tests, they set up the meter at the exhaust stack following CARB procedures defined on arb.ca.gov.
Mobile testing is especially valuable for fleets running yard-day bulk schedules and owner-operators who cannot afford a day off the road for a shop visit.
Ensure CARB state compliance fees are paid in CTC-VIS (commonly cited at $32.13 per vehicle—verify current amounts officially) before the appointment so results process smoothly.
Best candidates for mobile service
Multi-unit fleets at a single address, port-adjacent drayage operators, construction fleets parked overnight at job sites, and rural operators far from fixed inspection shops all benefit from on-site service.
Single-truck owners with dash lamps should still pre-diagnose when possible—a mobile visit saves travel time but does not magically pass a truck needing DPF or DEF repairs. Review OBD prep and what to expect before booking.
Testers offering mobile service list it on their Zurfex profiles—filter by ZIP and read reviews mentioning punctuality and yard professionalism.
