Santa Rosa Smog Checks - General Information & Options

Tristar Automotive in Santa Rosa, CA is a full-service smog check station.

Smog checks are generally required for vehicle registration or when transferring ownership of a vehicle. Here in Santa Rosa, CA a smog check is required on most vehicles every two years, a.k.a. biennial inspection. Registered vehicle owners in Sonoma County will receive an annual Registration Renewal notice from the DMV. Near the top, you may see "SMOG Certificate Required" - indicating a smog check will need to be performed before you can obtain a current vehicle registration.

As part of an ongoing effort to comply with state laws, California Department of Consumer Affairs (DCA) in cooperation with the Bureau of Automotive Repair (BAR) directs certain vehicles registered in Enhanced Smog Check Areas to Test-Only smog check stations in Santa Rosa and Certified STAR Smog Check centers. If your vehicle has been "Directed" as result of a random selection process or because it matches High Emmissions Profile (HEP) criteria, "Test-Only" or "STAR Station" will be indicated on your vehicle's registration renewal notice.
