At an intersection, a roundabout helps protect you by lowering the frequency and severity of a crash. Its design is effective as it encourages you to slow down and reduces the number of points where you could potentially crash with another vehicle.
If a crash does happen, you’re less likely to be seriously injured or killed because the speed and angle of impact is less damaging.
Where there are high levels of traffic, a roundabout might also have traffic signals to help manage traffic flow. Signalised roundabouts are especially effective in improving safety for people walking or cycling.
You must give way to vehicles already on the roundabout or entering the roundabout from a road to your right. Follow any instructions given by a sign, road marking or traffic lights.
Signal before entering and leaving the roundabout if you are turning left or right, as long as you can stay in control while signalling. If you’re driving straight through, don’t signal before entering the roundabout. Signal left when you pass the exit before the one you want.
