Most diesel and alternative-fuel vehicles over 14,000 lbs GVWR that operate in California — including many out-of-state trucks.
Stay legal without losing a day at a shop.
We test multiple trucks at your yard.
Diesel motorhomes that meet the GVWR rule.
If you operate in California, the program still applies.
Some gasoline, historical, military, and zero-emission vehicles may be exempt. Confirm your due dates in CTC-VIS.
On-board diagnostic Clean Truck Check for OBD-equipped engines. We connect, capture the data, and file it.
Smoke opacity plus visual inspection for engines that OBD testing does not cover.
Call or send the form. We match OBD vs opacity to your engine year.
Mobile service across LA, Orange, Riverside, and San Bernardino / Inland Empire.
CARB-credentialed tester on site. Most visits are under 90 minutes.
Passing results are submitted to the CARB CTC-VIS portal.
We diagnose CEL, DPF, DEF, and aftertreatment so you can retest.
All-in per vehicle. Travel, test, and CTC-VIS filing included.
CARB’s separate annual compliance fee is paid to CARB, not to Torque Edge. If the truck fails, diagnostic support is available from $250.
Based in Fontana. About an 80-mile service radius. Fleet yards welcome.
Other testers leave when the truck fails. That is where we start. CEL, DPF, DEF, NOx, aftertreatment — we find the fault, fix it, and run the Clean Truck Check again until it passes. Cummins, Detroit, PACCAR, International, and most other 14,000+ lb diesel platforms we support daily. If we cannot complete the test on-site, we tell you before we start.
Fast. Precise. No runaround.
Real technicians in Fontana — not a call center. Bilingual English and Spanish.

Master Technician
If the truck fails, Manny diagnoses the CEL, DPF, DEF, and aftertreatment so it can pass the retest.
“We had a truck stuck in limp mode 200 miles from the nearest dealer. Torque Edge connected remotely and had us rolling in 45 minutes.”
David K. Owner-operator
“They walked my tech through a DEF dosing unit replacement while monitoring the ECM data live. Incredible service.”

We typically reply within 15 minutes during business hours.
It is the Heavy-Duty Inspection and Maintenance (HD I/M) program. Subject vehicles must pass periodic emissions tests and stay current in CTC-VIS.
Most vehicles test twice per year. Starting October 2027, OBD-equipped vehicles are expected to test four times per year. Check your dates in CTC-VIS.
2013 and newer engines typically need OBD. 2012 and older typically need opacity plus a visual inspection. Tell us the engine year when you book.
The truck must be repaired and retested. Unresolved failures can lead to DMV registration holds, fines, and enforcement. We can diagnose the fault and retest after the repair.
If the vehicle operates in California and meets the GVWR rule, Clean Truck Check generally still applies. Confirm in CTC-VIS.
Yes, diesel motorhomes over 14,000 lbs GVWR. RV Clean Truck Check details.
The truck on site, a driver or key, and your CTC-VIS account if you already have one. We handle the test and filing.
