How to use a mini roundabout

You may have noticed some mini roundabouts popping up around Perth over the past few years and wondered what the rules are for travelling through one.

While mini roundabouts are subject to the same regulations as other roundabouts, their small size means that some rules work a bit differently in practice.

At a regular roundabout, if practicable, you must signal left when exiting. But on a mini roundabout, where the distance between one exit and the next is very short, this generally isn’t practicable.

All other signalling rules do however apply. So if you’re leaving a mini roundabout at the first exit and it’s less than halfway around, indicate a left turn before you enter. If continuing straight ahead or reasonably straight ahead along the road on which you entered, you don’t need to indicate as you enter the roundabout.

If you’re turning right - so exiting after the halfway point - indicate a right turn before you enter the roundabout.

A driver entering a roundabout must give way to vehicles within the roundabout. On larger roundabouts, this typically means giving way to the right. Mini roundabouts, on the other hand, may require you to give way to the left if a vehicle approaching from a road to your left enters before you.

When approaching a mini roundabout, be prepared to give way to vehicles using any of the other approaches, as all entries are in close proximity to each other. As at all roundabouts, use caution when entering, even if you have right of way, in case another driver has not seen you or falsely believes that they have right of way.
