Mobile CARB Clean Truck Check
We specialize strictly in California CARB Clean Truck Check compliance testing for eligible diesel trucks.
Mobile OBD2 Clean Truck Check (CTC)
The California Air Resources Board (CARB) Clean Truck Check program requires periodic emissions compliance testing for heavy-duty diesel vehicles. We perform the official OBD2 test on-site so your trucks never leave your yard.
What's included
- Official OBD2 CARB Clean Truck Check test
- On-site testing at your yard, terminal, or job site
- Direct submission of passing results to CARB
- Certification documentation for your records
- Single truck or full fleet appointments
What we do
- • CARB Clean Truck Check OBD Test (the official periodic compliance test)
- • Testing for 2013 and newer diesel trucks (14,000+ lb GVWR)
- • Fully mobile — on-site at your yard, terminal, or job site
- • Results reported directly to CARB with certification documentation
Eligibility & scope
We're a dedicated CARB Clean Truck Check testing service. To keep our service fast and focused, we only perform the following:
- • OBD-based Clean Truck Check testing only (no opacity / smoke testing)
- • 2013 and newer diesel model-year engines only
- • Testing and compliance reporting only — we do not perform diagnostics or repairs
If your truck needs repairs to pass, we recommend a qualified diesel repair shop and we'll be glad to re-test once it's ready.
