I am sure a lot of people locally do not know about or just ignore the following Revised Code of Washington law.
It is apparent from the amount of noise pollution around the Peninsula.
Maybe it is time to rescind the law because it seems to be ignored by both the offenders and the people paid to keep the peace, so to speak.
RCW 46.37.390:
Mufflers required — Smoke and air contaminant standards — Definitions — Penalty, exception.
(1) Every motor vehicle shall at all times be equipped with a muffler in good working order and in constant operation to prevent excessive or unusual noise, and no person shall use a muffler cut-out, bypass, or similar device upon a motor vehicle on a highway.
(3) No person shall modify the exhaust system of a motor vehicle in a manner which will amplify or increase the noise emitted by the engine of such vehicle above that emitted by the muffler originally installed on the vehicle, and it shall be unlawful for any person to operate a motor vehicle not equipped as required by this subsection, or which has been amplified as prohibited by this subsection. A court may dismiss an infraction notice for a violation of this subsection if there is reasonable grounds to believe that the vehicle was not operated in violation of this subsection.
