HVS Update 26-2021 | Main Roads WA

Update to Convoy Provisions within the Oversize Operating Conditions

Please be advised that the convoy provisions in the following operating conditions have been updated:

As a result of this update, up to four (4) OSOM vehicles may travel in convoy on the following additional roads:

  • Munjina – Roy Hill Road, Newman
  • Marble Bar Road, between Munjina – Roy Hill Road and the turnoff for Roy Hill, Christmas Creek and Cloudbreak mine sites.

During recent HVS Industry Workshop and Information Sessions held across the State, industry requested Main Roads consider applications on a case-by-case basis to expand the permitted routes for these larger OSOM convoys, where the proposed route adjoins the approved section of Great Northern Highway.

In response to receiving a request for the above roads, Main Roads undertook risk assessments during a trial move under the direction of a Main Roads Traffic Escort Warden.

The revised operating conditions are now available on the Oversize Overmass (OSOM) page on our website.

HVS Update 23-2021

Expressions of Interest Now Open – WA Heavy Vehicle Pilot Licence Reference Group

In early 2022, Main Roads Heavy Vehicle Services (HVS) will commence a review of the Heavy Vehicle Pilot Licence (HVPL) scheme, the first since the Licence implementation in 2016/17 and its associated Audit Regime implementation in 2020. 

The review will consider key areas including Training & Competency Assessment, the Pilot Code of Conduct, the Introduction of Standards for Audits, and Licensing and will seek to identify potential improvements to reflect the needs of the current WA environment.

To do this, HVS is establishing a Pilot Licence Reference Group to involve the transport industry, pilot associations, individual pilots, the Department of Training & Workforce Development and other stakeholders to consider significant aspects and inform decisions.    

The purpose of the Group is to ensure the transport industry and interested parties are able to participate in the considerations arising from the review where possible.  This is a voluntary representative advisory group established to:

  • create a forum for discussion and exchange of information on topics related to the review;
  • help identify opportunities, issues and concerns; and
  • act as a two-way communication link between Main Roads and stakeholders.

We are looking for a diverse group of participants and are eager to ensure a cross section of the Transport Industry and other relevant stakeholders are represented. 

The Group will be formed using an Expression of Interest (EOI) process. Expressions of Interest for membership of the Group will close on 17 December 2021. To find out more about the EOI process, the role of the Group and how you can get involved, please register via the button on the link below


Know what to do when it’s bigger than you

When you’re on the road, you may come across vehicles that are much bigger, wider and slower than you.

Oversize and overmass (OSOM) vehicles and road trains are built to transport very large loads on our roads. From truckies driving large, slow-moving road trains, to farmers moving large agricultural vehicles during seeding and harvest season.

It can be daunting sharing the road with these vehicles, but following these simple rules will make your trip a safer one.

How to safely navigate a vehicle that’s bigger than you

If you come across an OSOM or large agricultural vehicle, accompanied by a Heavy Vehicle Pilot or Traffic Escort Warden vehicle, please follow these simple steps:

  • Stay alert – you can’t always see what’s ahead, so it’s important you drive to the road conditions
  • Slow down – seeing a Heavy Vehicle Pilot or Traffic Escort Warden vehicle is a warning that there’s something big up ahead
  • Move left – oversize loads and large agricultural vehicles can take up more than half the road or may need to travel in the middle of the road to avoid power lines or other roadside items
  • Prepare to stop and follow directions – Heavy Vehicle Pilots and Traffic Escort Wardens are there to provide directions on how to safely navigate the oversize load

If the OSOM or agricultural vehicle is extra-wide, you may need to pull over completely for the vehicle to pass safely. Take care when re-entering the road – indicate and wait until the entire convoy has passed, including the last Pilot vehicle, where present. 

When following behind an oversize or agricultural vehicle, be patient and keep a safe distance. The driver will sometimes pull over and signal when it is safe for you to pass.

If the rear pilot waves you past or calls you over the UHF radio (using UHF Channel 40) and advises that it’s safe to overtake, proceed with extreme caution. As the driver, you are still responsible for ensuring it is safe to cross the centreline and overtake.
