In the State of California, smog check stations are divided into categories. Standard repair stations both inspect vehicles and sell repairs. Unfortunately, this creates an inherent conflict of interest where a dishonest mechanic might fail your car simply to charge you hundreds of dollars in unnecessary repairs.
At Main St Smog Star Station, California law prohibits us from doing any automotive repairs. We do not sell catalytic converters, oxygen sensors, or spark plugs.
- Zero Financial Incentive to Fail: Our sole priority is conducting an honest, accurate, and completely unbiased smog inspection.
- No Waiting Behind Big Repair Jobs: Because our bays are dedicated exclusively to smog tests, there are no long delays or mechanics tied up rebuilding engines.
- Fast In-and-Out Service: Average inspection takes only 15 minutes from key turn to printed vehicle inspection report (VIR).

Frequently Asked Questions
Find immediate answers to common California smog testing and DMV registration questions.
The California Department of Motor Vehicles selects vehicles for STAR testing based on two main criteria: a random statistical sample across registered California vehicles, or vehicles flagged by the state's High Emitter Profile (vehicles historically having higher emissions failure rates). When your notice specifies STAR, only a state-certified STAR station like Main St Smog can perform your inspection.
No appointment is ever needed! We accept walk-in customers Monday through Saturday from 8:00 AM to 5:00 PM. Our streamlined testing bays keep wait times minimal, with most inspections completed in approximately 15 minutes.
Please bring your DMV Registration Renewal Notice (the paper renewal form mailed to you by the California DMV) which contains a barcode our technician can scan to instantly pull up your vehicle record. If you do not have your renewal notice, your current registration card or vehicle title will work just fine.
Yes. Under California Bureau of Automotive Repair regulations, an illuminated Malfunction Indicator Lamp (Check Engine Light) is an automatic failure during the functional inspection, regardless of tailpipe emissions. We recommend having the underlying diagnostic code resolved before your smog inspection.
