- Station certification: STAR vs. basic smog station.
- Certificate fees: California adds $8.25 electronic filing fee.
- Retest policy: Some stations charge $15–25 if initial fails; others offer one free retest.
- Location premium: Urban centers (SF, LA) charge $10–20 more than rural areas.
- Drive at highway speeds 20 min before test — warms up catalytic converter.
- Ensure “Check Engine” light is OFF; unresolved codes = automatic fail.
- Check gas cap seal (loose cap triggers EVAP code).
- Use fuel system cleaner one full tank prior.
- Confirm OBDII monitors are “ready” (not incomplete).
Timeline: Smog test takes 20–30 minutes. STAR stations may require 40 min due to extra checks.
