How must I display the hulk hauler license plates? All vehicles used by hulk haulers on the highways of this state shall bear regular license plates and in addition, special hulk hauler's plates. Each vehicle shall display both special plates assigned to it, provided that when any vehicle being towed does not have valid license plates, the hulk hauler plates may be split, with one being displayed on the front of the towing vehicle and the other on the rear of the vehicle being towed. The plates serve in lieu of a trip permit or current license plates for the vehicle(s) being transported.
