Light trailer requirements

If you tow a light trailer (up to 3500kg when loaded), it must have a WoF. To meet the WoF standard your trailer must be in good condition (no rust around safety areas) and it must have the following equipment in good working order:

Loading your trailer safely

To ensure the stability of the vehicle and trailer combination when towing, the trailer should exert a downwards force on the towing vehicle's towbar equal to about 10 percent of the weight of the trailer plus its load.

The load on the trailer must not:

  • extend more than 4 metres behind the rear axle

  • extend more than 1.25 metres on either side from the centre of the trailer.

If the load extends more than 1 metre behind the trailer, you must tie on a white flag, or a red, orange or yellow fluorescent flag. The flag must be at least 40 centimetres by 30 centimetres in size. The load must be tied on firmly and must not touch the ground.
