Giving way at roundabouts

A roundabout is a central island in the middle of an intersection, where all vehicles must travel to the left of the island. Roundabouts can be small, large, single-laned or multi-laned. The number of roads that come into a roundabout can range from 3 to 5 or even more.

Single-laned roundabouts

When you come up to a roundabout that has only one lane in each direction:

• slow down as you come up to the roundabout and be prepared to give way
• give way to all vehicles that will cross your path from your right as you enter the roundabout.

Multi-laned roundabouts

Most roundabouts that have more than one lane in each direction are marked with lanes and arrows. The lane markings and arrows will tell you which lane to use. Not all roundabouts are marked the same way, so take extra care – especially at the exits. If you need to cross into another lane to exit, give way to any vehicles in the lane that you want to enter.

When coming up to a multi-laned roundabout:

• slow down as you come up to the roundabout and be prepared to give way
• be in the correct lane for where you want to go
• give way to all vehicles that will cross your path from your right as you enter the roundabout.

Signal use at roundabouts

If you're turning left at the first exit of a roundabout:

•  signal left as you come up to the roundabout.

Single-laned roundabout

 
If you're travelling more than halfway around a roundabout:

• signal right as you come up to the roundabout
• signal left as you pass the exit before the one you wish to take.

Single-laned roundabout

Multi-laned roundabout

 
If you're going straight through a roundabout:

• don’t signal as you come up to the roundabout
• signal left as you pass the exit before the one you wish to take. 

 
Look out for cyclists who may find it difficult to maintain a turn signal on a roundabout and are exempt from this requirement.
