Most cars have a maximum weight they can tow. It’s usually listed in the handbook or specification sheet.
Alternatively the vehicle’s ‘gross train weight’ may be listed on the vehicle identification number (VIN) plate on the car. This is normally under the bonnet or inside the driver’s door.
The gross train weight is the weight of the fully-loaded car plus fully-loaded trailer and must not be exceeded.
If your VIN plate does not list a train weight, you should not use your vehicle for towing.
Width and length
The maximum trailer width for any towing vehicle is 2.55 metres.
The maximum length for a trailer towed by a vehicle weighing up to 3,500kg is 7 metres. This length does not include the A-frame.
