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

In Germany, trucks with a gross vehicle weight rating (GVWR) over 3.5 tons, such as a 7.5-ton truck, are generally limited to a maximum speed of 60 km/h on main roads (Landstraßen) unless otherwise indicated by traffic signs. This speed limit is set to enhance road safety, considering the heavier weight and longer stopping distances of trucks compared to passenger cars. Therefore, when driving a 7.5-ton truck on main roads, you must not exceed 60 km/h to comply with traffic regulations and ensure safe driving conditions.
