What to expect at Monkey's Smog Center
Monkey's Smog Center is licensed by the Bureau of Automotive Repair as a Test Only smog station in Oakdale. It runs the inspection and issues the certificate but does no repairs. It is not STAR certified, so if your DMV renewal notice says "STAR Station Required" you will need a different station.
Walk-ins are welcome. 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?
- Monkey's Smog Center doesn't do repairs, so the car goes to a repair shop and comes back for the retest.
- Each station sets its own retest price, so ask before the first test.
- BAR's Consumer Assistance Program pays up to $1,450 toward emissions repairs for income-eligible owners.
