California Star Certified

In the state of California, it is a requirement for most vehicles to be smog-checked every two years at a smog inspection station. Once your smog test is completed, you will be given a smog inspection certificate that you will present when registering your new vehicle. After the initial check, you will then be required to re-certify every two years. Please do keep in mind that out-of-state smog inspection stickers do not meet California requirements, even if they happen to be current.

At Smogg Only, we are a STAR-certified smog check provider. This means you can come to us when you receive notice that your smog test can only be performed at one of these certified stations. Once your test is completed, we’ll automatically send the smog emission test certificate straight to the DMV.
