In addition, every such trailer or semitrailer except a semitrailer drawn by a truck-tractor type designed to draw or support the front end of a semitrailer, shall be coupled with stay chains or cables to the vehicle by which it is being drawn which chains or cable shall be of sufficient size and strength to prevent parting from the drawing vehicle should the regular coupling device break or become otherwise disengaged.
