You are driving a vehicle combination. It consists of a motor vehicle with a permissible maximum mass of up to 3.5 tonnes and a trailer that is authorised for speeds of up to 100 km/h. What is the maximum speed limit on a federal highway (not an expressway)?

When driving a combination consisting of a passenger car or light truck (up to 3.5 tonnes) and a trailer, the general maximum speed limit on German federal highways (Bundesstraßen) is 80 km/h. Even if the trailer is approved for 100 km/h, this higher speed is only allowed on motorways (Autobahnen), not on federal highways outside built-up areas. This rule ensures greater safety due to varying road conditions on federal highways. So, in this scenario, 80 km/h is the correct speed limit. Knowing the specific limits for different road types is important for safe and legal driving in Germany.
