The use of various devices used by heavy trucks, known as “engine brakes,” which convert the truck's diesel engine into a power-absorbing air compressor, resulting in a net energy loss to help control the truck's speed, makes a distinctive loud sound that can have a negative impact on residents within close proximity to a highway. Entrances to the City of Montague shall be posted with signage stating: “The use of engine or air brakes past this point is prohibited except when needed for safety.” Violation of this section is a misdemeanor.
