If mud flaps are used, they shall be wide enough to cover the full tread width of the tire or tires being protected; shall be so installed that they extend from the underside of the vehicle body in a vertical plane behind the rear wheels to within eight inches of the ground; and shall be constructed of a rigid material or a flexible material which is of a sufficiently rigid character to provide adequate protection when the vehicle is in motion.
