Many intersections have a central roundabout. Roundabouts manage
the traffic flow in roads with either a single lane or multiple lanes.

Do not drive on the central island of a roundabout unless the size
of your vehicle means that you cannot avoid the wheels crossing
the central kerb.

Making turns and giving way at roundabouts

Approaching a roundabout: Vehicles entering a roundabout must give
way to any vehicle already in the roundabout.
Giving way at a roundabout: means the driver must slow down and if
necessary, stop to avoid a collision.
Turning left: On your approach to a roundabout you must select the left
lane, signal left, stay in the left lane to exit.
Going straight ahead: Do not signal when approaching the roundabout
but always signal left before exiting a roundabout.
You may approach the roundabout from either left or right lanes (unless
there are road markings with other instructions), drive in the same lane
through the roundabout and exit in the same lane.
Turning right: On your approach, to a roundabout you must select the
right lane, signal right, stay in the right lane and signal left before exiting
into the right lane.
Making a U-turn: When you use the roundabout to make a U-turn on
your approach signal right from the right lane, stay in the right lane, but
signal left before exiting into the right lane.
Exiting a roundabout: If practical, you must always signal left when exiting a roundabout.

Roundabouts: Risks to watch for
• Take extra care whenever you drive in a roundabout.
• Keep an eye out for cars that are leaving the roundabout.
• Be careful if changing lanes in a roundabout, particularly
when leaving.
• Look out for vehicles that are making a full turn.
• Watch for bicycles, long vehicles and motorcycles.
