About California Smog Test

California Smog Test employs an ASE-certified staff to check cars to ensure they are road ready. They complete the DMV-required biennial smog testing by placing your vehicle on a dynamo meter to test for emissions. The team can certify diesel and regular cars and trucks, out-of-state registration changes, and renewals of your current smog approval rating. The staff also recommends you warm up your vehicle before a smog check, or, if your vehicle is more than a decade old, fill up the gas tank to help ensure a passing measurement.
