A STAR Test & Repair station is the only type of smog check center which can inspect, repair and certify any and all vehicles. These stations are participants of the State's Consumer Assistance Program and are inspected by the State of California monthly.
The STAR Program establishes performance standards for Smog Check stations and inspectors. STAR stations meet higher performance standards. Some STAR stations are licensed to perform only tests and others are licensed to perform both tests and repairs. Since 2013, Electric Lab has been licensed to perform both tests and repairs.
