What type of trailers used in agriculture and forestry do not have to have their own registration number?

In German traffic regulations, particularly concerning agriculture and forestry trailers, certain types of trailers are exempt from having their own registration number if they meet specific criteria.

Trailers with a "25" speed limit sign attached to the rear are designed for slower movement and are generally used in contexts where high-speed travel is unnecessary. These trailers do not require separate registration as they are considered part of the vehicle's load and not a standalone unit on the road.

Additionally, trailers that may travel in excess of 25 km/h must have their own registration number, as they pose different safety and regulatory considerations. Those used to transport agricultural goods successfully meet the requirements for not needing individual registration, provided they also adhere to the aforementioned speed limit.

Understanding this combination is crucial, as it helps ensure compliance with traffic laws and promotes safety on the roads, reflecting how agricultural operations can efficiently manage their vehicles without unnecessary bureaucracy.
