Failing to give way at a roundabout = 3 demerit points and $150 fine.
All other offences for not using a roundabout correctly = 2 demerit points and $100 fine.
When entering a roundabout, always give way to any vehicles already in the roundabout. On multi-lane roundabouts, obey the directional arrows on the road.
On approach, indicate left from the left lane. Stay in the left lane and exit the roundabout from this lane.
Driving straight ahead
You don’t need to indicate on approach. Enter in either the left or right lane, stay in and exit from the same lane. If practicable, indicate left when you’ve passed the last exit before the one you intend to use.
Turning right or making a full turn
On approach, indicate right from the right lane. Stay in the right lane and exit the roundabout from this lane. If practicable, indicate left when you’ve passed the last exit before the one you intend to use.
You can change lanes within a roundabout, but you must indicate and give way to other vehicles.
Cyclists & roundabouts
When entering a multi-lane roundabout, cyclists should move to the centre of their chosen lane.
Please note that in a single lane roundabout, cyclists should ride close to left boundary of the lane.
If you’re a motorist entering a roundabout, be aware of cyclists. While in the roundabout, don’t try to squeeze past or overtake them.
