100. Trailer
A trailer is a vehicle designed to be pulled by another vehicle rather than move under its own power. Trailers are used to transport goods, equipment, boats, caravans or other loads and can vary greatly in size and weight.
Drivers towing a trailer should make sure it is correctly coupled, properly loaded and suitable for the towing vehicle. The trailer can increase the combination's length, weight, stopping distance and space required for turning.

How is a trailer defined in Belgium?
A trailer is legally defined as any vehicle intended to be moved by another vehicle.
When do you need B96 or BE for a trailer in Belgium?
With a category B towing vehicle, a trailer of up to 750 kg maximum authorised mass is allowed under ordinary B. A heavier trailer is allowed under ordinary B if the combination does not exceed 3500 kg. Code 96 extends the latter combination limit to 4250 kg. BE normally covers a category B towing vehicle with a trailer up to 3500 kg; other categories or acquired rights may be relevant beyond those limits. The vehicle and coupling limits must also be respected.
