What does STAR smog check mean?

STAR is BAR's higher-standard certification.

  • Stations meet stricter equipment requirements
  • Directed vehicles must use STAR
  • Look for the STAR seal at the station

Per BAR (bar.ca.gov/smog-check).

Does a STAR smog check cost more than regular?

Not automatically — BAR doesn't set a price difference between STAR and regular stations. Each shop posts its own price.

  • STAR and non-STAR stations both set their own posted prices — there's no state-mandated STAR markup
  • Some vehicles are required by your DMV renewal notice to test at a STAR station, regardless of price
  • See our posted price on-site or on our services page

Prices are set per station, not by BAR — see our posted price for the exact cost.
