WA safety authorities have updated their guidance on quad bikes. 

The official document - Quad bikes in workplaces guide (PDF) - outlines the legal requirements for those operating or in charge of workplaces where quad bikes are used and will assist riders, as well as managers, to ensure they are operated safely.

The guide has been updated to reflect the changes in relation to the control of rollover and recognised need for helmets to be worn during quad bike use on private land. 

The authorities say that it should be read in conjunction with the operator manual for the specific quad bike used.
