What is the difference with a regular smog station and a STAR smog check station? You received your DMV renewal notice and discovered it's asking for a smog inspection at a STAR station. No need to panic. All this means is that the DMV has chosen your car to be inspected at a smog station which is monitored closely by the BAR (Bureau of Automotive Repairs) and must conform to high standards established by the BAR.
STAR Test & Repair - STAR Test & Repair stations are authorized by the BAR to perform, along with smog check repairs, regular smog inspections and test only smog checks. A STAR Test & Repair station is the only type of smog check station which can inspect, repair and certify any and all vehicles.
These stations are participants of the State's Consumer Assistance Program (CAP) and are inspected by the State of California monthly.
