Traffic Escort Services Overview

The Over Size – Over Mass (OSOM) Unit has been established in consultation with the transport and logistics industry, to facilitate the smooth running of operations involving OSOM loads throughout W.A. OSOM loads are large indivisible items, special purpose vehicles or agricultural machines or implements.

Road transport makes a vital contribution to Western Australia’s economy. Due to the State’s remote and rugged nature, there is often no alternative but to move very large items by road.

Vehicles carrying OSOM loads come in a wide variety of shapes and sizes, typically moving much slower than ordinary traffic and taking up a greater proportion of road width than other vehicles. The movement of OSOM loads by road is strictly regulated to ensure safety for all road users. For more information regarding sharing the road with OSOM Loads please read our OSOM Loads, Pilot and Traffic Escort Vehicles brochure.

Traffic Escort Wardens are managed by Main Roads and authorised by the Commissioner of Police to facilitate the safe movement of OSOM loads on the Western Australian road network. Traffic Escort Wardens ensure the safe travel of all OSOM movements an escort is required if a load is wider than 5.5 metres in width and/or longer than 40 metres in length, and any oversize loads moving on the freeway, Abernethy Loop or movement through the bollards.

Traffic escort vehicles are equipped with red and blue flashing lights situated on the roof of the vehicle.  These will be in use when the vehicle is escorting an OSOM load. The vehicle also has the words “Traffic Escort” displayed on both sides of the vehicle. They are operated by Traffic Escort Wardens who for the purpose of facilitating safe movement of these loads and road users have the same power as a Police Officer.

OSOM loads are usually accompanied by one or more Pilot vehicles and the largest OSOM loads are also accompanied by a Traffic Escort vehicle. Their job is to warn other road users of the presence of large, slow-moving loads. Pilot vehicles are identified by their orange flashing lights and warning signage on the roof of the vehicle, and Traffic Escort vehicles are easily identified by their distinctive flashing red white and blue roof-mounted lights and warning signage.

If you would like further advice regarding sharing the road with OSOM loads including, what to do when encountering an OSOM load on your journey, please see the “sharing the roads with OSOM Loads” or view our “OSOM Loads, Pilot and Traffic Escort Vehicles” brochure.
