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?

For trucks with a gross vehicle weight of up to 3.5 tons, the maximum speed outside built-up areas is 100 km/h. However, for trucks between 3.5 and 7.5 tons, including those with a 4.0 t rating, the maximum speed allowed on country roads outside of towns and cities is 80 km/h. You selected the correct answer because the law limits these heavier trucks to 80 km/h for safety reasons such as braking distance and accident risk. Remember: Always check the vehicle’s weight class to determine the correct speed limit outside settlements.
