§ 440.12  ENGINE BRAKES (JAKE BRAKES).
   (a)   For purposes of this section, the term “Jake brake” shall mean an engine brake of the type originated and/or manufactured by Jacobs Vehicle Systems, or a similar device, which mounts on a motor vehicle engine, changes the action of the exhaust values, and provides retarding power which is proportional to the engine’s revolutions per minute (RPM), so as to slow the motor vehicle.  The term “motor vehicle” shall have the same meaning given to such term in § 402.22.
   (b)   No person, while operating a motor vehicle within the municipality, shall activate a Jake brake on such motor vehicle unless the other braking devices on such motor vehicle have failed or exigent circumstances exist which require the use of such Jake brake.
