Which vehicles are prohibited from using a road sign-posted like this?

This traffic sign indicates a restriction based on the actual axle weight of vehicles. It prohibits vehicles with an actual axle load exceeding 2 tonnes from using the road. This means that trucks or any vehicles whose weight pressing down on one axle is more than 2 tonnes are not allowed to pass.

It is important to understand that this limit refers to the real, measured weight on the axle (actual axle weight), not just the permissible or allowed maximum weight according to registration (permissible axle weight) or the total vehicle weight.

The rule helps protect road surfaces and bridges from damage caused by heavy axle loads. Knowing this, you can correctly identify that vehicles exceeding the actual axle weight of 2 tons must avoid this road, ensuring compliance with weight restrictions and road safety regulations in Germany.
