Quick answer: A test-only station performs Smog Checks but makes no emissions repairs. A test-and-repair station does both. A STAR station meets higher performance standards, and your DMV notice says if you need one. These definitions are BAR’s.

The station types BAR describes

  • Test-and-repair station: performs Smog Checks and emissions repairs.
  • Test-only station: performs Smog Checks but does not make emissions repairs.
  • STAR station: meets higher performance standards to inspect all vehicles, including high-polluting vehicles. Your DMV registration renewal notice will say if you need to go to a STAR station.
  • Repair-only station: repairs emissions issues but does not perform Smog Checks.

Which type should you choose?

  • Your notice says “Smog Certification Required at a STAR station.” Use a STAR station. It may be test-only or test-and-repair.
  • Your notice says “Smog Certification Required.” Any station licensed for Smog Check inspections will do.
  • You are retesting after a failed inspection. BAR says to use a STAR station if your notice requires one; otherwise any test-and-repair or test-only station. A test-only station has no repair work to sell you, which is why some drivers choose one for a retest.

Frequently asked questions

Is a test-only station cheaper than a test-and-repair station?

Not necessarily. BAR does not regulate inspection prices, so every station sets its own. Get an estimate from a few stations before you choose.

Can any station do my retest after a fail?

BAR says to go to a STAR station if your DMV registration renewal notice requires one. If not, you can go to any test-and-repair or test-only station.

What is a repair-only station?

BAR says a repair-only station repairs emissions problems but does not perform Smog Checks.

Can a station be both STAR and test-only?

Yes. STAR is a set of performance standards, and BAR lists STAR alongside test-only and test-and-repair as station types. On our city pages, STAR stations are marked separately from test-only and test-and-repair.
