Sharing the Road With Oversize Vehicles

Oversize spray on bedliner are a vital part of the rural development in Western Australia. WA is a huge state and road transport is the only way some items can be transported around the state. Just have a look at some of the huge mining trucks.

There are many types of oversize vehicles, all of which display a sign indicating that the vehicle is greater than the standard width or length. The standard width for a truck is usually no more than 2.5 metres wide and cars are around 1.9 metres wide.

Headlights on and OVERSIZE sign displayed. This indicates the vehicle (or load actually) is up to half a metre wider than the normal vehicle width and/or 22 to 25 metres long.

Headlights on, an amber rotating beacon and a pilot vehicle in front with amber beacons and OVERSIZE VEHICLE FOLLOWING signs. This indicates the load is up to 4.5 metres wide and/or the vehicle is up to 30 metres long.

You should slow down and be prepared to move off the side of the road. When you do this be aware of loose gravel on the side of the road and of course and guideposts, drains, culverts etc.

Headlights on, OVERSIZE signs, an amber rotating beacon, a pilot vehicle in front with amber beacons, flashing headlights and OVERSIZE VEHICLE FOLLOWING signs and a Police escort with blue and red flashing lights. There will also be a pilot vehicle with amber beacons and flashing headlights at the rear. This indicates the load is over 5.5 metres wide and/or the vehicle is over 30 metres long.

You should slow down move off the side of the road. When you do this be aware of loose gravel on the side of the road and of course and guideposts, drains, culverts etc. and wait for a signal from the rear pilot before moving back onto the road. Note – Pilot vehicles are usually some distance in front of the loads to give you plenty of warning. So slow down and stay at a lower speed until you have passed the oversize vehicle.

Further Note – Sometimes two oversize vehicles travel in convoy with one another and may be escorted by only one pilot where applicable. Normally, the two loads are not too far apart, but with normal road conditions and traffic etc this may cause them to be further apart than usual. Be aware of this and make sure the road is clear ahead before pulling back onto the road to ensure the second vehicle has had time to pass, particularly when there is no rear pilot vehicle. Additional Further Note – When meeting an oversize vehicle (or any vehicle for that matter) on a narrow sealed section of road, slow down and move as far left as practicable. This will reduce flying debris like stones that can cause your windscreen to break and dust which could impair your vision.
