Smog Check Program Areas

The Smog Check program divides the state into three different types of areas depending on the severity of the smog problem in that area. These areas, Enhanced, Basic, and Change-of-Ownership Areas, may require different Smog Check inspection equipment and different licenses. The area in which a vehicle is registered will determine which type of test a vehicle needs; the area in which a station is located will determine which licenses the technician needs to possess and what equipment a station must have to test vehicles in its area. The ZIP Code locator function on this www site can be used to determine in which type of area a station is located or a vehicle is registered.
