Welcome to Hayward Smog Test Only

Hayward Smog Test Only is a state of California licensed STAR smog check test only center. We can smog and certify all vehicles:
  • Diesel
  • Gross polluter
  • STAR directed
  • Change of ownership
  • Biennial registration renewal
  • Out of state initial registration

Smog test only stations can only smog and certify vehicles. By law we cannot diagnose or repair smog failures. We do offer one free retest if you fail to ensure you that we will not benefit anything from your vehicle failing. In other words, we want you to pass the first time.
