C+EDifficulty 3/5

A lorry tows a non-agricultural semi-trailer that is 7 metres long. Must that semi-trailer be equipped with side position lights?

Correct answer

Yes, because its length exceeds 6 metres.

Yes, because the semi-trailer is longer than 6 metres. Article 16.5 of the General Vehicle Regulations requires side position lights on non-agricultural trailers and semi-trailers exceeding that threshold. This does not mean they are mandatory on every semi-trailer regardless of length.
