Which requirements must be met so that a farm trailer is exempt from registration?

You selected both correct answers. For a farm trailer to be exempt from registration in Germany, two conditions must be fulfilled: First, it can only be towed by a tractor unit or self-propelled working machine and must not exceed 25 km/h. Second, its use must be limited to agriculture or forestry purposes.

The rule ensures that only slow-moving, agricultural vehicles—that are not used for commercial transport—benefit from this exemption. An official inspection every 12 months is not a requirement for this exemption, which is why answer 3 is not correct. Remember, always check both the technical condition (speed and towing vehicle) and the permitted use when dealing with exemptions for farm trailers.
