(925) 443-7474Got a DMV notice telling you to go to a STAR station, or a vehicle flagged as a gross polluter? Those tests can't be done just anywhere. As a STAR-certified station in Livermore, we handle directed tests, official certifications, gross polluter certification, and retests after repairs. Bring the notice with you and we'll take it from there.
Learn MoreDiesels, hybrids, lifted trucks, RVs, and classic cars don't test like a standard sedan — and a lot of stations turn them away. We're equipped for the odd ones, including multi-vehicle fleets that need several units certified without tying up your whole week. Call ahead with your year, make, and model and we'll confirm we can test it before you drive over.
Learn MoreMost California vehicles need a smog check every two years to renew registration, and the reminder usually shows up with a deadline that's closer than you'd like. We run the full inspection — OBD scan, visual, and functional checks — and transmit your results straight to the DMV, so there's no paperwork for you to hand-carry. Walk-ins are welcome, and we'll tell you upfront what the test costs before we touch your car. If something fails, you'll get a plain-English explanation of what's actually wrong instead of a printout you can't read.
Learn MoreRenewing your tags, selling a car, buying one, or bringing a vehicle in from out of state — each one triggers a different smog requirement, and the rules trip people up constantly. We handle registration renewal checks, change-of-ownership smogs, out-of-state inspections, and VIN verification under one roof in Livermore. Tell us what you're trying to accomplish and we'll tell you exactly which test applies to your situation. Your certificate goes to the DMV electronically the same day, so your registration isn't held up waiting on us.
