A GUIDE TO SAFE AND LEGAL TOWING  

Trailer Weight Limits

The maximum weight that a vehicle can tow safely can be found in the manufacturer’s handbook.

Additionally, the vehicle identification number (VIN) plate may list the vehicle’s gross train weight – which is the weight of the fully loaded vehicle plus a fully loaded trailer. The gross train weight must not be exceeded. If the VIN plate does not list a train weight, the vehicle should not be used for towing.

PLEASE NOTE: when it comes to the law, the plated gross vehicle weight of the trailer is the weight that should be used when establishing whether your vehicle can tow it legally – and safely. This is the combined weight of the trailer and the maximum load it is designed to carry. It doesn’t matter if the trailer is empty – you will still be breaking the law if the plated gross vehicle weight of your trailer exceeds the maximum weight for your towing vehicle.


Trailer Width & Length Limits

If the towing vehicle weighs 3,500 kg or less:
• Maximum trailer width allowed: 2.55 metres
• Maximum trailer length allowed: 7 metres (excluding coupling and drawbar)

If the towing vehicle weighs more than 3,500 kg:
• Maximum trailer width allowed: 2.55 metres
• Maximum trailer length allowed: 12 metres (excluding coupling and drawbar) – must have 4 wheels
• Maximum combined length of towing vehicle and trailer: 18 metres
• Maximum overhang of load from rear of trailer: 3.05 metres
