Jake brakes

What is your take on the jake brake situation again addressed by city council? The council mentioned the topic during their Monday, May 16 meeting, citing the possibility of creating a noise ordinance to prohibit the engine brakes in some parts of town. Signs prohibiting the brake retarders will be placed in some areas of town. Do the tractor-trailers go to fast to begin with? Shouldn't they use any means necessary to stop their vehicles in case of an emergency situation up ahead? Aren't motorcycles extremely loud as well? Let us know your thoughts.
