What is the maximum permissible length of the truck and trailer with load?

The maximum permissible length of a truck with a trailer and load in Germany is 20.75 meters. This length limit ensures that the vehicle combination can safely maneuver on roads, particularly when turning or braking.

In your illustration, "X" represents the total length from the front of the truck to the end of the last trailer, including the load. This total length must not exceed 20.75 meters for legal and safe driving on German roads.

If the length exceeds this limit, the vehicle may require special permits or be restricted from certain roads. Staying within this limit helps maintain road safety and traffic flow by preventing excessively long vehicle combinations.

Your answer is correct: knowing the maximum permissible length helps you understand legal limits for trucks and trailers with loads in Germany.
