# Do I need an appointment for a smog check, and are stations open on weekends?

Most smog check stations take walk-ins, and many are open on Saturday; fewer open on Sunday. Hours and wait times vary by station, so call before you go: AppointAuto lists each station's phone number, website and directions by city. Calling ahead also lets you confirm the total price and whether the certificate fee is included.

## Key facts

- There is no state rule requiring an appointment for a smog check.
- Station hours vary; confirm by phone before driving over.
- The $8.25 state certificate fee applies only when the car passes.

## Questions to ask on the phone

- Are you open now, and how long is the wait?
- What is the total price, including the $8.25 certificate?
- Is a retest free or discounted if the car fails?
- Are you a STAR station? (Only needed if your DMV notice says so.)
