In ordinary traffic, with no specially designated route or extraordinary shoulder authorisation, which vehicles must use the right shoulder if it is passable and sufficient?

Correct answer

Special vehicles with an MAM not exceeding 3500 kg

Special vehicles with an MAM not exceeding 3,500 kg are among those required to use it in this situation; if it is not passable and sufficient, they use the necessary part of the carriageway. Merely weighing less than 1,500 kg does not qualify any vehicle. Motorcycles have no such ordinary duty, although extraordinary use exists on expressly authorised and signed sections when lanes are stopped by congestion, in single file at no more than 30 km/h, protecting users required to travel on the shoulder.
