You are driving an agricultural tractor with a maximum design speed of 40 km/h. You are permitted to tow what maximum number of trailers that have a maximum permissible speed of 25 km/h?

You are allowed to tow up to two trailers with an agricultural tractor that has a maximum speed of 40 km/h, as long as the trailers themselves are approved for a maximum speed of 25 km/h. This is set by German road traffic regulations to ensure safety when slower vehicles are operating on public roads, especially when towing. Choosing two trailers is correct—towing more would not be permitted with your tractor under these conditions. Remember this limit whenever driving agricultural vehicles with trailers.
