CARB 5-day pass (official link)
Most drivers never find this. It’s a CARB temporary pass — not a substitute for a Clean Truck Check. We put the real link here so you’re not hunting PDFs.
- Once per VIN per calendar year · five consecutive calendar days
- Request through CTC-VIS (CARB’s portal) — keep approval in the truck
- Does not make the truck fully “compliant” long-term · still need your real OBD/OVI when due
Need the actual test after the pass? We come to your yard — 916-890-4427 · OBD $75 · OVI $199.
Rather not deal with CARB at all?
