You only have a Class B and D1 driving licence. Your bus has the following data: - empty mass 5,000 kg - permissible total mass 7,500 kg - permissible towed load 2,000 kg What is the permissible total mass of a trailer you are pulling?

With a Class D1 licence, you are allowed to drive minibuses with no more than 16 passenger seats and a maximum length of 8 meters, and you may tow a trailer with a maximum permissible mass of 750 kg. Even if your bus could technically tow a heavier trailer, the law limits you to a trailer that does not exceed 750 kg with a D1 licence. That’s why answer 1 (750 kg) is correct. With a Class B licence, the rules for towing with cars are separate and do not apply to buses. To tow a trailer over 750 kg with a bus, you would need a D1E licence. Knowing which trailer weights are allowed for each licence class helps ensure you always stay within legal limits and avoid penalties.
