You are holding a driving permit class C1. Your truck has the following specifications: - empty mass 3500 kg - permissible total mass 6200 kg - permissible towed load 9300 kg Which trailer are you allowed to tow?

As you hold a driving permit for class C1, you are permitted to drive vehicles with a permissible total mass of up to 7.5 tons, including any trailers you may tow. The permissible towed load of your vehicle is 9300 kg, which indicates the maximum weight of a trailer you can legally tow.

In this case, you need to consider the weight of the trailer you can tow in relation to your vehicle's specifications. The choices offered were:

1. 750 kg
2. 3500 kg
3. 6200 kg

When selecting a trailer to tow, the weight of the trailer must be below the permissible towed load of 9300 kg. The option of 750 kg is valid since it's well within the limits.

The other options, 3500 kg and 6200 kg, would also be permissible to tow as they are less than 9300 kg. However, since the question likely expects you to choose the maximum allowable lightweight option, it’s essential to recognize all the correct choices limit and hitch compatibility for safe driving.

Understanding this not only keeps you within the legal limits but also ensures safe driving conditions, as towing too much weight can strain your vehicle's capabilities and pose a risk on the road.
