Star Smog Depot is a family owned and operated smog test only station that has been serving the Colma and Daly City area for over 8 years. During smog checks, our STAR Certified smog technicians identify the amount and type of pollutants released by your vehicle as it runs. They test the exhaust pipe and other emissions systems for an average of 15–20 minutes, then measure the results against California's standards. Vehicles that pass the smog test can then receive their smog certification — a biennial requirement for many Californians. You can expect to receive top-notch smog emission testing at a competitive price!
