What to expect at Downey Smog

Downey Smog runs the inspection and issues the certificate but does no repairs. It is STAR certified, so it can test vehicles the DMV directs to a STAR station, including gross polluters.

Its coupon says no appointment is needed. 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?

  • Downey Smog doesn't do repairs, so the car goes to a repair shop and comes back for the retest.
  • BAR's Consumer Assistance Program pays up to $1,450 toward emissions repairs for income-eligible owners.
