12 A motor vehicle, except a motorcycle, shall be equipped with a front bumper, and where a replacement bumper has been installed, it shall give substantially the same protection as the bumper originally installed by the manufacturer.
A motor vehicle shall be equipped with a rear bumper where the manufacturer of the vehicle installed a bumper, and where a replacement bumper has been installed, it shall give substantially the same protection as the original bumper.
A bumper shall be securely fastened to the vehicle, and the bumper bar or brackets shall not be broken, loose or missing.
A bumper must not have a sharp or ragged edge and must not protrude beyond the side of the vehicle.
