Drivers in California have a responsibility to protecting the environment. SDS Automotive is committed to helping drivers fulfill this responsibility through its Star-certified test-only facilities. SDS Automotive performs vehicle smog tests that are required every two years. SDS Automotive facilities are true professionals and will provide an honest assessment of the situation with a three-part test consisting of a visual inspection, a functional examination, and an emissions evaluation. Since we are also a repair shop, SDS Automotive has the ability to help if your vehicle fails a test.
