1. What is a Smog Check?
The Smog Check Program is an important part of the State’s efforts to improve the air we breathe. Smog Check inspections are designed to identify vehicles with excess emissions so they can be properly repaired. The Smog Check Program has greatly reduced air pollution created by millions of cars in California. According to the California Air Resources Board, the program removes about 400 tons of smog-forming pollutants from California’s air every day.
2. Is my vehicle subject to Smog Check?
Gas-powered vehicles 1976 and newer require a Smog Check, with the following exceptions:
- Vehicles six model years and newer do not need a biennial (every other year) inspection.
- Vehicles four model years and newer do not need a change-of-ownership inspection.
- Diesel-powered vehicles 1998 and newer with a gross vehicle weight rating (GVWR) up to 14,000lbs also require a Smog Check.
- Motorcycles and electric-powered vehicles are currently exempt from the Smog Check Program.
3. How often does my vehicle have to be tested?
If your vehicle is subject to Smog Check, it must be tested every other year. An inspection is also required if you sell a vehicle and when registering a vehicle for the first time in California.
4. Do I need to take anything with me to my Smog Check?
Remember to take your Department of Motor Vehicles (DMV) registration renewal form with you when getting a Smog Check. This will help ensure that the correct vehicle information and test results are electronically sent to DMV.
5. What is a STAR station?
Some vehicles require a Smog Check at a STAR station. STAR stations must meet specified performance standards established by the Bureau of Automotive Repair (BAR). Some STAR stations are licensed to perform only tests, while others are licensed to perform both tests and repairs. The station is required to post a sign on the services it performs.
