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?

In this scenario, the permissible total mass of a trailer you can pull when you have a Class B and D1 driving licence is limited by both the permissible towed load of your bus and the weights associated with the bus itself.

According to German traffic regulations, for a bus under your driving license with a permissible total mass of 7,500 kg, you need to consider the empty mass of the bus (5,000 kg) and the maximum towed load (2,000 kg). This means that when towing a trailer, the combined weight of the bus and the trailer must not exceed 7,500 kg.

Calculating the allowable maximum weight of the trailer:

1. Total permissible weight of the bus and trailer = 7,500 kg
2. Empty weight of the bus = 5,000 kg
3. Therefore, maximum weight of the trailer = 7,500 kg - 5,000 kg = 2,500 kg

However, you are limited by both the permitted total load and the specific category restrictions of your driving licence. With a Class B and D1, you may only tow a trailer that aligns with these limits. Under current regulations, the largest single trailer you could tow under a Class B would generally align with 750 kg unless additional conditions are met or different license classes allow for heavier trailers.

Thus, understanding these regulations will ensure compliance with German traffic laws and promote safety on the road.
