What can be done to stop noise from jake brakes/compression engine brakes?

The State has adopted motor vehicle regulations that address the configuration and condition of vehicles operated on roads and highways. These regulations require a vehicle be equipped with a proper exhaust system and compression engine brake muffler. Engine brakes on commercial vehicles help control vehicle speed on long downgrades. This reduces the risk of brake fade which provides safer interaction between vehicles on all roadways. 

Although Castle Rock police officers are not certified in commercial vehicle inspections, officers can stop commercial trucks that appear to emit a louder than normal noise level when using compression engine brakes and inquire as to whether or not the vehicle is equipped with a compression engine brake muffler. If the officer determines the truck doesn’t have the proper muffler, a citation or warning can be issued.

Police officers have conducted observations throughout Town to determine the number of trucks that appeared to be operating trucks without proper compression engine mufflers. Observations showed of the 61 commercial motor vehicles, seven used a compression engine brake. No muffler violations were detected.
