You may call for a Referee appointment if you have received a citation for 27156, modified emission controls. 

 

If cited for 27156 (modified emission controls): The vehicle must pass a complete Referee inspection, which includes ensuring the vehicle's computer programing is not tampered. It is strongly recommended the vehicle has no modified equipment or modified programing prior to making your Referee appointment. Failure to correct any modifications prior to the Referee appointment will result in significant delays.  

If cited for 27150 or 27151 (Modified/Loud Exhaust): Assembly Bill 1824 changed the way that noise citations work. We can still inspect your vehicle and issue a certificate if it passes. The fee for a Referee noise inspection certificate is $108. Receiving a certificate may not necessarily remedy the violation and the court could still issue a fine in addition to the Referee fee. 

If you have been cited for Vehicle Code Section 27150 or 27151, your vehicle's exhaust system may have deteriorated, or it may be modified resulting in noise level that exceed current standards. It is recommended that you obtain repairs as soon as possible to prevent being cited again. 

It is important to note that citations have a court appearance date. Failure to appear in court on the specified date can result in additional fines and penalties. 

The California Vehicle Code sections 27150 and 27151 require that all vehicles must be equipped with an adequate muffler to prevent exhaust noise from exceeding 95 decibels.

California Vehicle Code section 27150.2.(a) prohibits BAR's Referee contractor from performing an exhaust noise test on a vehicle unless the vehicles has been cited for violating Vehicle Code section 27150 or 27151. For Brake and Light inspections, please call the Bureau of Automotive Repair at 1.800.952.5210 to locate a station.

NOTE: The Referee is unable to perform a decible reading on vehicles with a Gross Vehicle Weight Rating (GVWR) greater than 5,999 lbs. To verify the weight, please see the sticker located in the driver's door pillar/jamb. If greater than 5,999 lbs, contact the court for further guidance.
