Smog Check Center

Your vehicle may not be ready for a Smog Check if you recently disconnected or replaced the battery.

Drive your vehicle for a week or two to allow the readiness monitors to reset before taking it in for a Smog Check.

To determine the first year most vehicles need a biennial Smog Check, add eight to the model year of a vehicle.

For example, a 2020 model-year vehicle will first be subject to a biennial Smog Check in 2028 (2020 + 8 = 2028).
