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.
