Please be advised the following operating conditions have been updated:

• Single Trip OSOM Vehicle Standard Operating Conditions
• Class 1 RAV Oversize Period Permit Operating Conditions
• Special Purpose Vehicle Standard Operating Conditions

The changes to the operating conditions have been driven by feedback received during our HVS Industry Workshops and Information Sessions held across the State.

In addition, Main Roads provided the opportunity for industry to offer feedback about the proposed changes last month, via the My Say Transport website. Thank you to those who took the time to provide feedback.

The feedback received has been considered and where appropriate, has been incorporated into these changes to the operating conditions.

As such, the revised Operating Conditions are now available on our website and will come into effect from 1 September 2021.
