What total mass must a truck with trailer (two-axle truck, three-axle trailer, not combined traffic) not exceed?

In Germany, the regulations for vehicle combinations, including trucks with trailers, are outlined in the Road Traffic Regulations (StVO) and the Road Traffic Licensing Regulations (StVZO). For a two-axle truck towing a three-axle trailer, the maximum permissible total mass is crucial for safety and structural integrity on the roads.

The total mass limit ensures that the combination can be safely handled, preventing accidents caused by overloading, which can impact braking efficiency, maneuverability, and stability. The correct mass not exceeding for such combinations is typically 40 tons for general cases, which is often the specified limit under normal traffic regulations.

Understanding these rules helps drivers ensure compliance, thus enhancing road safety for everyone. It's important to be aware of all correct options in such questions, as they may refer to various permissible limits under different conditions or scenarios in the regulations.
