What to expect at Frontinos Auto Clinic

Frontinos Auto Clinic can run the inspection and, if your car fails, diagnose and fix it in the same shop. Its STAR certification is currently suspended in the BAR registry, so it cannot test DMV-directed vehicles until that is restored.

Most smog checks take 15 to 30 minutes, and most visits are closer to 20.

What to bring

  • Your registration or DMV renewal notice

    It says whether the car needs a STAR station.

  • The car, with the check engine light off

    On a 2000-or-newer car, a lit check engine light fails the test on its own.

  • A way to pay

    The $8.25 state certificate is paid on top of the test when the car passes, unless the station's price or coupon includes it.

What if I fail?

  • Frontinos Auto Clinic can diagnose and repair the problem in the same shop, then retest the car.
  • BAR's Consumer Assistance Program pays up to $1,450 toward emissions repairs for income-eligible owners.
