About Us

Smog Testing Services

For the smog test on your vehicle to be valid, you must complete the test at a STAR-certified smog station. We complete all necessary testing for your DMV renewals to be processed,and once the smog test is complete, we instantly email your certification directly to the DMV.

If your vehicle is registered in another state, our technicians certify your vehicle with our standard, STAR-certified smog test. As soon as your vehicle is certified, we give a printed report to you so that you can complete your registration in the appropriate state.

We offer the following services:

  • DMV renewal smog tests
  • Regular smog inspections
  • STAR smog inspections
  • Light-duty diesel smog tests
  • Gross polluter certifications
  • Initial registration smog tests

Whatever your smog test needs are, we will gladly meet them.
