Smog Check for Clayton, CA
Clayton's go-to STAR smog station, 15 minutes away.
Clayton drivers have been skipping the closer options and choosing Super Station Concord for over three decades. We are a STAR Certified station authorized for every smog test type — regular, directed, and gross polluter — and most checks are done in under 30 minutes.
Driving from Clayton
Straight shot down Clayton Road
From Clayton, head west on Clayton Road and turn south onto Monument Boulevard. Super Station Concord is on the left at 1650 Monument Boulevard. Depending on traffic, it is about a 15-minute drive — often shorter outside of peak commute hours.
We see Clayton customers from the Oakhurst Country Club area, Marsh Creek Road neighborhoods, and downtown Clayton near Main Street. Clayton's closer smog options are sometimes not STAR Certified, which matters if your DMV renewal notice specifically directs you to a STAR station.
If your vehicle fails the smog check, we are also a full-service repair shop — we can diagnose and fix the issue the same day, then retest at no extra smog check fee.
