What is the maximum speed you may drive with a combination of vehicles which consists of a truck and two trailers with overrun brakes?

In Germany, when you have a combination of vehicles consisting of a truck and two trailers, both having overrun brakes, the maximum allowed speed is 25 km/h. This strict speed limit is set for safety reasons because such long combinations are more difficult to control, especially during braking and turning. Driving faster than 25 km/h could lead to instability and increased risk of accidents. Understanding this rule is important to ensure you operate these vehicle combinations safely and legally on public roads.
