What is the maximum number of trailers with overrun brakes are you allowed to tow with a truck tractor when you intend to drive the truck/trailer combination at a speed of more than 25 km/h?

According to German traffic regulations, if you are driving a truck with a trailer and plan to exceed 25 km/h, you are only allowed to tow one trailer, even if it is equipped with overrun brakes. This rule exists to ensure road safety, as towing more than one trailer at higher speeds makes the combination harder to control and increases stopping distance. Therefore, the only correct answer is "1 trailer." This limitation helps prevent dangerous driving situations on public roads.
