Need a Certified Smog Test or Emissions Test?

The State of California requires the Department of Motor Vehicles to direct certain cars and trucks to “Test Only” Smog Inspection Stations which Brothers Smog Shop is one. Test Only stations tend to produce more realistic and accurate emissions data, helping to keep the air as clean as possible. If your registration renewal notice is marked as Test Only, be sure to bring that notice with you.

We are able to perform smog checks or smog inspections on any vehicle for registration renewal, transfer of ownership, or recently stored out of state vehicles. Your Smog Check requirement notice from the DMV DOES NOT HAVE TO BE A TEST ONLY FACILITY. Bring your vehicle to Brothers Smog Shop where we have the latest equipment and technology available to ensure the most accurate results. Our Dynamometers are in ground to ensure the safety of your lowered vehicle. We also accommodate interlocking systems and vehicles with installed driver assisted systems and those with modified steering systems.

We are committed to providing you with fast, friendly and quality service.
