Emissions testing checks how much pollution your car sends into the air. In Livermore, most drivers need this test to register their car or renew their tags. Our team runs your emissions testing quickly, so you can get back to your day. We test cars from Livermore, Tracy, Dublin, and Pleasanton every week.

When You Need Emissions Testing

You need emissions testing before you register a vehicle in California, when your DMV renewal notice tells you a smog check is due, or when you buy or sell a used car. Some drivers wait until the last minute, but a failed test can mean repairs, and repairs take time. Common causes of high emissions are old spark plugs, a clogged catalytic converter, or a check engine light that has been ignored. Bay Area air quality rules are strict, so the state checks emissions closely. If your check engine light is on, get it looked at before your appointment. Waiting can lead to a failed test and a second trip to the shop.

Our Emissions Testing Process

We hook your car up to state-approved equipment and check your tailpipe emissions and onboard computer, depending on your vehicle's model year. A technician looks over your car, runs the test, and reviews the readout with you in plain language. Most emissions tests take about 20 to 30 minutes from start to finish. If your car passes, we send the results straight to the DMV, so you don't have to do any paperwork. If it doesn't pass, we explain what we found and what your options are. You can wait in our lobby or drop your car off and run errands nearby in Livermore.

  • Tailpipe or OBD test based on your car's model year
  • Check engine light and dashboard warning light review
  • Gas cap and visible hose inspection for leaks
  • Onboard computer scan for stored emissions codes
  • Plain-language readout review with a technician
  • Passing results sent straight to the DMV same day
