Driving with a category B driving licence:
With a B/96 combination driving licence a person is entitled to drive a vehicle combination with a Category B towing vehicle (with a maximum total mass of 3 500 kg) and a trailer whose total mass exceeds 750 kg and the total mass of the vehicle combination can exceed 3 500 kg but not 4 250 kg.
With a category BE driving licence a person can drive a vehicle combination with a category B towing vehicle (maximum total mass 3,500 kg) and a towed vehicle with a maximum total mass of 3,500 kg. The total mass of the vehicle combination can be a maximum of 3,500 + 3,500= 7,000 kg.

For vehicle A the maximum permissible mass of a trailer being towed is 1 500 kg (information is available from the registration certificate). According to the registration certificate, the total mass of trailer P is 1 800 kg. Towing trailer P with vehicle A is permitted if the actual mass when it is being towed is a maximum of 1 500 kg.
If trailer P is loaded to 1 500 kg when being towed, but its total mass according to the registration certificate is 1 800 kg, towing vehicle A can weigh a maximum of 1 700 kg so that the driver can drive the combination with a B license (total mass of the combination can be a maximum of 3 500 kg).
Thus if the towing vehicle A weighs more than 1 700 kg, a B96 or BE license is needed. In this case, with a B96 license the weight of towing vehicle A can be a maximum of 2 450 kg. However, someone driving on a BE license should note that towing vehicle A is a B category vehicle when the total mass of the trailer P is 1800 kg.
When pulling a trailer, the maximum permitted driving speed is 80 km/hour, also when the trailer is empty.
