Roads and Maritime Services (replacing Roads and Traffic Authority) has established regional Council Weight of Loads Groups (WOLG) as part of its asset protection strategy, which have been operational over a number of years.
Heavy vehicle enforcement in NSW is about maximising road safety and managing infrastructure of the NSW community, while ensuring the ongoing efficiency of the freight industry in NSW.
Role of WOLG
The primary objective of WOLGs is to ensure that heavy vehicles using council and state roads are complying with statutory loading requirements, and to enforce load limits and reduce wear from heavy vehicle overloading.
Membership
There are five WOLG groups across NSW. Each of these groups consists of a number of member councils within a certain area. The table below outlines the member councils for each Weight of Loads Group:
