Mobile Clean Truck Check
in Ontario.
We bring a CARB-credentialed tester to your Ontario yard, run the OBD test on-vehicle, and submit the passing result to CTC-VIS the same day — no shop trip, no downtime.
Clean Truck Check for Ontario Fleets
Ontario is the air-cargo and last-mile hub of SoCal. ONT International drives freight through UPS and FedEx sort operations off Archibald and Airport Drive, and the warehouse belt along Mission and Jurupa is stacked with private and for-hire fleets. Between airport support tractors, drayage rigs, and the local delivery fleets, the density of >14,000 lb diesels here is one of the highest per square mile in California.
We roll a CARB-credentialed tester into Ontario yards and knock out Clean Truck Check testing between shifts. The OBD result gets filed to CTC-VIS immediately, so your Clean Truck Check compliance stays green without pulling a single unit off route.
What Happens If You Miss Your Clean Truck Check Deadline
CARB can block your registration renewal until you're compliant. No sticker, no legal operation.
Per vehicle, per day, for operating out of compliance. Penalties stack fast across a fleet.
Your compliance status is checked on the spot. Non-compliance means out-of-service and citations.
