What is the maximum speed you are allowed to drive a truck with a permissible total mass of 40 t on autobahns?

In Germany, trucks with a permissible total mass of 40 tons are subject to specific speed limits on different types of roads. On autobahns, the speed limit for such trucks is set at 80 km/h. This regulation is outlined in the Road Traffic Regulations (StVO) to ensure safety and efficiency on high-speed roads, where heavier vehicles need to maintain a regulated pace to prevent hazards.

Understanding and adhering to this speed limit is crucial for the safe interaction between trucks and lighter vehicles, promoting smoother traffic flow. Moreover, following these regulations helps in avoiding penalties and contributes to overall road safety. Make sure to always stay updated with local traffic laws, as they can sometimes differ across regions or be updated.
