You are holding a driving permit class C. Your truck has the following specifications: - empty mass 9000 kg - permissible total mass 18000 kg - permissible towed load 22000 kg Which trailer are you allowed to tow?

With a class C driving permit in Germany, you are allowed to drive trucks with a permissible total mass (Gesamtgewicht) over 3.5 tons and tow a trailer, but the trailer's weight is limited. Specifically, the trailer's permissible total mass must not exceed 750 kg if the truck's permissible total mass is between 7.5 and 12 tons, unless you have an additional trailer permit.

In your case, your truck has a permissible total mass of 18,000 kg (18 tons), and the allowed trailer load is 22,000 kg. However, your class C license only allows towing trailers up to 750 kg without an additional endorsement. Therefore, you are allowed to tow the 750 kg trailer, but not the heavier ones.

This rule ensures that drivers have adequate skills and safety knowledge before towing heavy trailers with large trucks. To tow trailers heavier than 750 kg, you need a class CE license, which includes additional training and testing.
