"Motorists who have a vehicle that requires a smog check prior to registration are notified by the DMV approximately 90 days before the registration is due. A percentage will be directed to a test-only facility, while the remainder may go to any state certified smog check station.
As the name implies, test-only centers are authorized to provide only a smog test and are certified to perform ALL smog checks, re-registration, change of ownership, out-of-state registration, gross polluters, smog check and, of course, test only.
The ADVANTAGE you have by coming to us is simple: We sell you a test and ONLY THE TEST. We are not motivated to sell you repairs, because we can't perform repairs. If your vehicle should fail, you will be given the test results, which will guide you toward narrowing in on what repairs need to be done. Once you have those repairs done by your own service facility, bring your car back in to us. Our tests are not bias in any way!"
