A load on a heavy vehicle must not be placed in a way that makes the vehicle unstable or unsafe and must be secured so it’s unlikely to fall or dislodge.  Any method of restraint used must comply with the National Transport Commission’s Load Restraint Guide.

The guide provides transport drivers, operators, and other participants in the transport chain of responsibility with basic safety principles which should be followed for the safe carriage of loads on road vehicles.

Loads that are permitted to move relative to the vehicle include loads that are effectively contained within the sides or enclosure of the vehicle body such as:

  • loads which are restrained from moving horizontally (limited vertical movement is permissible)
  • very lightweight objects or loose bulk loads (limited horizontal and vertical movement is permissible)
  • bulk liquids (limited liquid movement is permissible).
