(B) The driver of any truck or motor vehicle drawing another vehicle when traveling upon a roadway outside of a business or residence district, and which is following another truck or motor vehicle drawing another vehicle shall, whenever conditions permit, leave sufficient space so that an overtaking vehicle may enter and occupy the space without danger, except that this shall not prevent a truck or motor vehicle drawing another vehicle from overtaking and passing any vehicle or combination of vehicles.
(C) Motor vehicles being driven upon any roadway outside of a business or residence district in a caravan or motorcade, whether or not towing other vehicles, shall be so operated as to allow sufficient space between each vehicle or combination of vehicles so as to enable any other vehicle to enter and occupy the space without danger.
