Draft animals, pack animals, riding animals, or loose livestock shall travel along the right-hand shoulder and, if they must use the carriageway, they shall do so keeping as close as possible to the right-hand edge of it; as an exception, it is permitted to lead a single such animal along the left-hand edge if greater safety reasons so advise. They are completely prohibited from travelling on motorways or dual carriageways.
