(d) This Section does not apply to specially designed or modified motor vehicles when operated off the highways. Such motor vehicles may be transported upon the highway only by use of a trailer or semitrailer. The specially designed or modified motor vehicle may also be transported upon another vehicle, providing that the entire weight of the specifically designed or modified vehicle is resting upon the transporting vehicle.

Except as indicated below, maximum bumper heights of such motor vehicles shall be determined by weight category of gross vehicle weight rating (GVWR) measured from a level surface to the highest point of the bottom of the bumper when the vehicle is unloaded and the tires are inflated to the manufacturer's recommended pressure.

For any vehicle with bumpers or attaching components which have been modified or altered from the original manufacturer's design in order to conform with the maximum bumper requirements of this section, the bumper height shall be measured from a level surface to the bottom of the vehicle frame rail at the most forward and rearward points of the frame rail. The bumper on any vehicle so modified or altered shall be at least 4.5 inches in vertical height and extend no less than the width of the respective wheel tracks outermost distance.
However, nothing in this Section shall prevent the installation of bumper guards.
