Why East Bay drivers come to Concord for SMOG checks
Concord sits at the center of the East Bay's highway network, making Super Station Concord accessible from most surrounding cities in 15 minutes or less. The station is located at 1650 Monument Boulevard with direct access from Highway 242 and Interstate 680.
What to know before your appointment
No matter which city you are driving from, the same California SMOG rules apply. Check your DMV notice to see if a STAR station is required, make sure the check engine light is off, and allow enough drive time for your vehicle's engine to warm up before the test.
If your vehicle recently had the battery disconnected or codes cleared, you may need to drive additional miles so the onboard readiness monitors complete their cycles before testing.
STAR certification matters
Super Station Concord is a STAR-certified test-and-repair station. If your DMV notice directs you to a STAR station, this qualification means the inspection will satisfy that requirement. Drivers who are not sure whether they need STAR can check their renewal notice or call 925-685-0101 for guidance.
