Larger Road Trains Get Green Light on WA Highway Under Trial Conditions

10 Apr Blog

The Western Australian Government has announced a three-month trial allowing longer road trains on a key section of Great Northern Highway in the Wheatbelt region.

Triple-trailer road trains measuring 53.5 metres will now be able to travel between Wubin and Muchea on Great Northern Highway, provided they meet strict safety requirements. Drivers must also have at least three years of experience operating vehicles of that size. Previously, these longer vehicles had to be split into shorter double-trailer configurations before passing south of Wubin toward Perth.

The trial is designed to boost efficiency and cut down on the number of truck trips needed along this critical corridor, which links Perth to several regional areas including the Wheatbelt, Murchison, Goldfields, Pilbara, and Kimberley.

The move is one of several measures the WA Government is rolling out to support freight operators and keep supply chains running smoothly amid ongoing fuel supply pressures.

Premier Roger Cook said the change would help get goods to regional WA more quickly, while Transport Minister Rita Saffioti emphasized the Government’s commitment to working alongside the transport industry to maintain economic stability in the face of fuel security challenges stemming from the Middle East conflict. Saffioti also noted that the Government had acted swiftly on feedback from freight industry leaders to deliver practical improvements in productivity and fuel efficiency.

This latest announcement builds on a prior decision to allow certain 27.5m and 36.5m road trains to carry up to 10 additional tonnes per load when transporting petrol, diesel, and/or fertiliser to designated priority regions.
