Whether you’re driving in the Perth metro area or through regional WA, trucks and heavy vehicles are a common sight moving goods around this vast state.

It is vital that truck and heavy vehicle drivers and other road users share the road responsibly.

Overtaking heavy vehicles safely

In regional WA, you will encounter some of the longest trucks in the world. Road trains range in length from 33 metres to up to 60 metres, and common sense and care is required to safely overtake these vehicles.
  • It can take some time to safely overtake a road train, so take your time and stay several car lengths behind the truck.
  • Be patient and wait for a long stretch of straight road with a clear view of what is ahead.
  • When it is safe to pass, indicate, move over the centre lane, accelerate to the posted speed limit, and overtake sensibly.
  • Only return to the left-hand lane once you can see both headlights on the truck in your rear-view mirror.
  • If you are towing a caravan or trailer, or the road conditions are less than ideal, it is best not to try and overtake at all. Wait for an overtaking lane, where it is safe to do so.

Stopping distances for trucks and heavy vehicles

Trucks and heavy vehicles weigh a lot more than the average vehicle on the road, and therefore require extra stopping distance at traffic lights, stop signs and traffic congestion.

Trucks and heavy vehicle drivers purposely leave a large space between their vehicle and the vehicle in front, to allow enough braking distance when required.

Do not cut in front of a truck or heavy vehicle as the weight behind the vehicle means the driver may not have enough room to stop before hitting you.

Beware of a truck’s blind spot

Drivers of heavy vehicles and truck use their mirrors to stay aware of what is around them, but if you sit in a truck’s blind spot you will be invisible to the driver.

If you can’t see the sideview mirrors on a truck while travelling behind the vehicle, the driver cannot see you approaching.

Drivers are also unable to see vehicles at various points around the vehicle, particularly the left-hand side, so if you’re a driver, motorcyclist, cyclist or pedestrian, stay clear of the passenger door and make yourself visible to the driver.
