What is the maximum permissible length of a combination of a truck and one trailer if a load does not project backward?

You answered correctly. In Germany, the maximum allowed length for a combination of a truck and one trailer, provided the load does not stick out at the back, is 18.75 meters. This limit is set to ensure safety and maneuverability on roads, especially when turning or navigating through traffic. Knowing the legal maximum helps prevent accidents and ensures compliance with road regulations for longer vehicles. If the length is exceeded, it can lead to higher risks or legal penalties. Therefore, always check that the total length of your truck and trailer does not surpass 18.75 meters unless special permission has been granted.
