CTC Inland Mobile Compliance brings CARB Clean Truck Check OBD testing straight to your yard, terminal, or lot — anywhere in Southern California. No shop. No downtime.
We're a fully mobile CARB Clean Truck Check testing provider serving fleet operators and independent owner-operators across Southern California. Instead of routing your trucks to a testing station, we bring the test to you — so compliance happens between loads, not instead of them.
Vehicles over 14,000 lbs GVWR operating in California are required to complete Clean Truck Check testing on a recurring schedule and have passing results submitted to CARB's CTC-VIS database. Your due month follows your DMV plate expiration.
We're phasing in services as we complete certification on each testing method.
For diesel and alternative-fuel vehicles with model-year 2013 or newer engines. We connect a CARB-verified OBD device at your location, confirm your emissions system is reporting correctly, and file the result to CTC-VIS before we leave.
For older engines — MY2012 and earlier — that are tested by smoke opacity rather than OBD. We're completing equipment certification now. Coming soon.
Three steps, all of it handled without you leaving your lot.
Tell us your VIN, engine year, DMV plate expiration, and where to meet you. We'll confirm your compliance window.
A technician meets you wherever your trucks are — yard, terminal, jobsite — with a CARB-verified OBD scan tool.
Passing results go straight into CARB's compliance database before we leave.
Fully mobile, no shop to drive to — we cover all of Southern California from a home base in the Inland Empire.
Since we're 100% mobile, there's no facility to schedule around. Tell us where your trucks are — a distribution center, a jobsite, a rented lot — and we'll route a technician there.
Running more than a few units? We'll plan a single visit that works through your whole fleet in one stop.
Send us a few details and we'll confirm a date and location that fits your compliance window.
