Smog Checks – What to Expect
During a smog check at our Santa Rosa STAR Certified center, a certified technician will attach diagnostic equipment to your vehicle to measure emissions output. This data is transmitted to the Bureau of Automotive Repair (BAR). The results of the smog check are referred to as Vehicle Inspection Report or VIR. If your vehicle passes the smog test, the BAR will transmit the Certificate directly to the Department of Motor Vehicles (DMV).
