Last updated: 04 August 2026

This code of practice provides guidance for a person conducting a business or undertaking on managing health and safety risks in relation to establishing and implementing a traffic management plan at a mine site. 

It is designed to provide guidance on: 

  • establishing a risk management process for operating mobile plant 
  • developing a principal mining hazard management plan (traffic management plan) 
  • defining principles for haul road design 
  • defining haul road maintenance standards 
  • establishing principles for the selection, operation and maintenance of powered mobile plant. 

The code of practice focuses on using the risk management process and ensuring effective traffic management controls are used within any applicable workplace. It should be used by those who have functions and responsibilities for planning, designing, implementing, and maintaining roads or vehicle operations on a mine site. It may also be useful for supervisors, operations personnel, and representatives who need to understand the responsibilities associated with traffic management procedures.
