Overtaking on WA roads might seem simple, but there are strict rules and real dangers — especially when it comes to trucks and cyclists. Western Australian drivers are being reminded to refresh their understanding of overtaking laws to avoid fines, reduce crashes and help protect vulnerable road users.

General Overtaking Rules

When overtaking another vehicle:

  • Always check for a clear view ahead.
  • Signal your intention using your indicator.
  • Never exceed the speed limit.
  • Do not cut in too closely after passing.

Illegal overtaking includes:

  • At intersections or pedestrian, railway or children's crossings.
  • Where 'no overtaking' signs are posted.
  • When crossing single or double continuous centre lines.

Overtaking on the Left

You may overtake on the left only when:

  • On a multi-lane road.
  • Directed by an authorised person (e.g., police).
  • The vehicle ahead is stationary and safe to pass.
  • A vehicle is turning right or performing a U-turn.

Overtaking Cyclists

To overtake bicycles safely:

  • Leave 1 metre when speed is 60km/h or less.
  • Leave 1.5 metres when speed is over 60km/h.

Drivers may cross continuous lines or painted islands if needed — but only when safe to do so and with a clear view of oncoming traffic. If safe overtaking isn’t possible, wait until it is.

Overtaking Trucks and Road Trains

WA roads often see massive road trains, which can be over 50 metres long. Overtaking these requires:

  • Patience.
  • A long, straight stretch of road.
  • Full visibility of both truck headlights in your rear-view mirror before merging back.
  • Avoid overtaking when towing or in poor road conditions.

Blind Spots

If you can’t see a truck’s mirrors, the driver can’t see you. Avoid driving:

  • Close behind trucks.
  • Alongside their left-hand side.
  • Near their front corners.

Safe Stopping Distances

Trucks need more space to stop. Never cut in front after overtaking. Leave them room — they leave long gaps for a reason. Respect their space.

Final Reminder

WA authorities encourage all drivers to stay visible, stay patient, and follow the road rules. Overtaking isn’t just about getting ahead — it’s about getting home safe.
