16. Roundabout

A roundabout is a circular road arrangement in which traffic travels around a central island in one designated direction. Vehicles enter and leave through connecting roads, and traffic signs or local rules determine who has priority.

Drivers should reduce speed, choose a suitable lane, observe all road users and signal as required when leaving. The direction of travel, entry priority, lane use and rules for cyclists and pedestrians depend on local traffic signs and regulations.

Who has priority at a roundabout in Australia?

In New South Wales, a driver entering a roundabout must give way to vehicles already in it. This is not a blanket duty to yield to every vehicle approaching from the right outside the roundabout. Other Australian jurisdictions have their own rules.

How should you choose a roundabout lane in Australia?

In New South Wales, follow the lane arrows and the Road Rules for a left turn, right turn or straight-ahead movement. Check before changing lanes and give way as required; priority at entry does not give priority for a lane change.

What should you check when leaving a roundabout in Australia?

Check the lane you will cross or enter, signal the manoeuvre as required and look for cyclists and pedestrians at the exit. Obey any separate crossing controls and do not force an exit across another vehicle’s path.
