Why this is the answer
The correct answer in the official bank: A more than 120cm wide trailer or semi-trailer, without floor and walls, which is designed to carry long freights.
A trailer or semi-trailer built for long freight, with no floor and no walls, is mostly an open frame, so its width and outline are hard to see. When it is more than 120cm wide, it must carry chains or cables, plus lamps during lighting up time, so other road users can see its edges. Protruding or oversize freight is covered by separate marking and permit rules.
