You are holding a driving permit class D. Your bus has the following specifications: - empty mass 13000 kg - permissible total mass 18000 kg - permissible towed load 2000 kg Which trailer are you allowed to tow?

With a class D driving permit, you are generally allowed to drive a bus and tow a trailer with a maximum permissible mass of up to 750 kg. To tow a trailer that exceeds 750 kg, you would need a special extension (class DE). In this case, since the only trailer within the allowed limit is 750 kg, only answer 1 is correct. Trailers of 1000 kg or 2000 kg are not permitted with the standard class D license. Always check the limits for your license class before towing a trailer with a bus.
