You are driving a combination vehicle. This consists of a motor vehicle with up to 3.5 t maximum authorised mass and a trailer without a 100 km/h approval. What is the maximum speed you can travel on the motorway?

You answered correctly. If you are driving a combination vehicle with a towing vehicle up to 3.5 t maximum authorised mass and a trailer that does not have a 100 km/h approval, the maximum speed allowed on the motorway is 80 km/h. In Germany, trailers without a special permit (so-called 100 km/h approval) must not be driven faster than 80 km/h when towed by passenger cars or light commercial vehicles. This rule exists for safety reasons, as trailers may behave differently at higher speeds. Always check if your trailer has the 100 km/h sticker before exceeding 80 km/h; otherwise, keep to the 80 km/h limit.
