The rules outlined below are an overview, please refer to the rule references for more details.
A roundabout is an intersection with a roundabout sign at each entrance, a central island and one or more marked lanes, or lines of traffic, all of which have vehicles travelling in the same direction.
- You must always keep to the left of the central island.
- You must drive in the direction of signs and/or arrows on the road before or in a roundabout.
When entering a roundabout, you must give way to any vehicle in the roundabout and any tram entering or approaching the roundabout. There is no requirement for vehicles to give way to pedestrians at roundabouts unless there are specific crossings provided.
In a roundabout, cyclists and animal riders have the option of turning right from the left lane, but they must give way to drivers exiting the roundabout.
If there are multiple lanes you must approach in the left lane and stay in that lane. You must indicate a left turn on your approach to the roundabout and keep the indicator on until you have left the roundabout.
If there are multiple lanes you must approach the roundabout in the right lane and stay in that lane. You must indicate a right turn on your approach, and indicate left, if practicable, just before the exit you are turning into, keeping the indicator on until you have left the roundabout.
If there are multiple lanes, approach the roundabout in the left or right lane. Drive in the same lane through the roundabout. Do not signal on your approach to the roundabout, but if practicable, signal left as you exit.
