Smog Check Stations Fact Sheet
The Bureau of Automotive Repair (BAR) licenses and contracts with several different types of Smog Check stations to meet the needs of consumers and their vehicles. Stations are required to post a sign so that consumers can easily identify them. Look for the station's official sign when selecting a station to perform your next Smog Check.
Smog Check Station Types and Services
STAR stations must meet specified performance standards established by BAR. Some STAR stations are licensed to perform only tests, while others are licensed to perform both tests and repairs. BAR directs a portion of the vehicle fleet to STAR-certified stations for inspection and certification. These are known as "directed vehicles." Additionally, vehicles that fail inspection at very high emissions levels must also receive certification from a STAR-certified station. These vehicles are identified as "gross polluters." The Department of Motor Vehicles registration renewal notice indicates if a vehicle requires inspection at a STAR station.
Test-Only stations are licensed to test and inspect vehicles.
Test-and-Repair stations are licensed to test, inspect, diagnose, and repair vehicles.
Repair-Only stations are licensed to diagnose and repair vehicles.

As with other consumer products and services, it is always best to shop around and to seek quality services. Since market forces drive the price of a Smog Check and any related repair work, some stations may charge different prices than others. To find a Smog Check station, click here or call 800.952.5210.
