What is the maximum speed you are allowed to drive a truck with a 4.0 t gross vehicle weight rating on roads outside of settlements?

In Germany, trucks with a gross vehicle weight rating (GVWR) over 3.5 tons are generally limited to a maximum speed of 80 km/h on roads outside of settlements. This speed restriction is designed to enhance safety because heavier vehicles require longer braking distances and have different handling characteristics compared to passenger cars. The rule helps prevent accidents by ensuring trucks travel at speeds appropriate for their size and weight. Therefore, for a truck with a 4.0 t GVWR, the maximum allowed speed outside built-up areas is indeed 80 km/h.
