No person shall use a compression braking system in conjunction with the operation of a motor vehicle, except for a person operating an emergency services vehicle (a fire engine or similar apparatus) equipped with a muffled exhaust braking system or except to avoid imminent danger to person or property. Compression braking systems, commonly found on trucks and busses and referred to as “Jake” brakes, convert an internal combustion engine into an air compressor for the purpose of slowing or stopping a vehicle with the use of wheel brakes.
