49-966.  Motor vehicle bumper height requirements. (1) With the exception of motor vehicles registered pursuant to section 49-406, 49-406A, 49-407 or 49-408, Idaho Code, or motor vehicles where the original or predominant body configuration of the motor vehicle, provided by a recognized manufacturer, did not include a front or rear bumper or bumpers for vehicles meeting the original specifications of a recognized manufacturer, a motor vehicle shall be equipped with a bumper on both the front and rear of the vehicle.
(2)  Bumpers, unless specifically exempt in subsection (1) of this section, shall be at least four and one-half (4 1/2) inches in vertical height centered on the vehicle’s centerline by bolting or welding to the vehicle frame as originally installed by the vehicle manufacturer.
