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?

When driving a combination vehicle in Germany, consisting of a motor vehicle up to 3.5 tons maximum authorized mass (MAM) and a trailer that does not have approval to travel at 100 km/h, the maximum permitted speed on the motorway is 80 km/h. This speed limit ensures safety because trailers without 100 km/h approval may not have the necessary stability or braking capability for higher speeds. Therefore, even if the motor vehicle alone can legally drive faster, you must limit your speed to 80 km/h when towing such a trailer. This rule helps prevent accidents caused by instability or insufficient braking performance of the trailer at higher speeds.
