What is the maximum speed you are allowed to drive a truck with a 7.5 t gross vehicle weight rating on main roads?

For trucks with a gross vehicle weight rating over 3.5 tons and up to 7.5 tons, the maximum speed allowed on main roads (also known as Landstraßen, or outside built-up areas) in Germany is 60 km/h. This is set by law to ensure safety, as heavier vehicles need longer braking distances and can cause more severe accidents at higher speeds. Always remember to adjust your speed to road, weather, and traffic conditions, even if the maximum permitted speed is higher. In summary, with a 7.5 t truck on main roads, the legal maximum is 60 km/h.
