Heavy-Duty Diesel Inspection & Periodic Smoke Inspection Programs
HDVIP requires heavy-duty trucks and buses to be inspected for excessive smoke, tampering, and engine certification label compliance. Any heavy-duty vehicle traveling in California may be inspected, including vehicles registered in other states and foreign countries. CARB inspection teams perform tests at border crossings, California Highway Patrol (CHP) weigh stations, fleet facilities, and randomly selected roadside locations. Owners of trucks and buses found in violation are subject to minimum penalties starting at $300 per violation. Penalty payment and proof of correction must be supplied to clear violations.
PSIP requires diesel and bus fleet owners to conduct annual smoke opacity inspections of their vehicles and repair those with excessive smoke emissions to ensure compliance. CARB randomly audits fleets, reviews maintenance and inspection records, and tests a representative sample of vehicles. All vehicles that do not pass the test must be repaired and retested.
