SMOG CHECK PROGRAM FACT SHEET
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. 

Areas of the State 

All areas of California require Smog Check inspections when a vehicle changes ownership or is registered for the first time in California. Most areas also require testing every two years, at the time of registration renewal. The Smog Check program divides the state into three areas, with different requirements for each:

Enhanced Areas: These areas do not meet federal or state air quality standards for ozone and carbon monoxide and are California's smoggiest urbanized areas. Biennial Smog Checks are required here. Fifteen percent (15%) of the vehicles in these areas must have their biennial Smog Checks performed at Test-Only stations.

Basic Areas: Vehicles in these less-smoggy areas must have biennial testing at licensed test-and-repair stations.

Change of Ownership Areas: These more rural areas of the state require emissions testing only when a vehicle changes ownership or are registered for the first time in California.

Testing Equipment New Equipment in Enhanced Areas: Enhanced Area stations use new equipment called the BAR-97 Emissions Inspection System (EIS), which uses a treadmill-like device called a dynamometer to simulate actual driving conditions. BAR-97 measures oxides of nitrogen (NOx), hydrocarbons (HC), and carbon monoxide (CO). Large trucks, some four-wheel drive vehicles, and some vehicles with traction control will continue to receive BAR-90 inspections.BAR-90: Vehicles registered in Basic and Change of Ownership Areas continue to be tested on a BAR-90 system that performs a 2-speed idle test which identifies HC and CO levels only.
