What is the maximum speed you are allowed to drive a truck with a permissible total mass of 4.0 t on autobahns?

Trucks with a permissible total mass of 4.0 tons are subject to specific speed limits on autobahns as per German traffic regulations. The maximum speed of 80 km/h is established to ensure safety and reduce the risk of accidents involving heavier vehicles. This limit is crucial because heavier vehicles require longer stopping distances and have different handling characteristics compared to lighter vehicles.

According to the German Road Traffic Regulations (StVO), trucks over a certain weight are restricted to lower speeds to maintain safety for all road users. Understanding and adhering to these limits helps prevent accidents and ensures more efficient traffic flow on the highways. Always remember to check for any specific signs indicating changes to speed limits or additional regulations that may apply to trucks or specific road sections.
