What is the California Smog Check Program?
The California Smog Check Program is an important part of the State’s efforts to improve the quality of the air we breathe in the state. The California Smog Check Program removes hundreds of tons of smog-forming pollutants from California’s air every day.
Because of the California Smog Check Program, the Department of Motor Vehicles sends periodically a registration renewal notice which indicates if a smog check is required. If the DMV requires a smog check for a vehicle, the owner must comply with the notice within 90 days. Following the smog check, the vehicle owner can provide a completed smog check certificate.
Smog Check inspections are designed to identify vehicles with excess emissions, so they can be repaired. Once properly repaired, these vehicles can meet state and federal emissions legal standards. These are often labelled California legal, California compliant, or CARB compliant.
A smog check inspection is performed by a station that has been licensed by the California Bureau of Automotive Repair. Depending on the situation, the owner may be required to take the vehicle to one of the following types of smog check stations:
- Test-and-repair stations can both perform the smog check and repair the vehicle
- Repair-only stations can only repair the vehicle but cannot perform the test itself
- Test-only stations can perform the smog check test but cannot make repairs
- STAR stations meet higher performance standards. Some STAR stations are test-only stations, while other STAR stations are test-and-repair
Registration will not be renewed until a smog check certificate is provided by the vehicle’s owner following the smog test check. If the vehicle fails the smog check, the owner will be required to complete all necessary repairs and pass a smog check test again to complete the registration. If the costs of repairing the vehicle outweigh its value, the state may buy it, and have it scrapped. The buyback program is part of California’s Consumer Assistance Program that also offers consumer assistance for repairs related to smog check.
The California Smog Check Program is entirely administered by the California Department of Consumer Affairs’ Bureau of Automotive Repair.
