Roundabouts Lessons Note

A roundabout consists of a central island and one or more lines of traffic that travel in the same direction. Always keep left of the central island.

When you enter a roundabout, you have to slow down and give way to all vehicles already in the roundabout. Enter only when there is a safe gap.

You should only use the left lane if you’re going to leave the roundabout during the first half or earlier. If arrows are marked before or in the roundabout, you must follow the direction of the arrows.

Turning left at roundabouts

  1. Approach in the left lane and signal on approach
  2. Stay in that lane and keep signalling until you have exited the roundabout

Going straight ahead at roundabouts

  1. Approach in the left or right lane but don't signal on approach
  2. Keep in the same lane throughout the roundabout
  3. You must signal left as you pass the exit before your exit unless impractical (e.g. the roundabout is too small)

Turning right at roundabouts

  1. Approach in the right lane and signal right on approach
  2. Drive close to the central island
  3. You must signal left as you pass the exit before your exit unless impractical
  4. Follow the right lane when you exit the roundabout

Making U-turns at roundabouts

  1. Approach in the right lane and signal right on approach
  2. Drive close to the central island
  3. Signal left as you pass the exit before your exit unless impractical
  4. Follow the right lane when you exit the roundabout

Using roundabouts correctly

Using roundabouts correctly is essential to prevent dangerous situations.

Changing lanes

You’re allowed to change lanes in roundabouts as long as you indicate where you’re going and make the lane change safely.

Bicyclists

Bicycle riders may travel in either lane no matter where they intend to exit. If turning right from the left lane, the rider must give way to all vehicles leaving the roundabout when passing an exit.

Roundabout risks

Roundabouts are generally safet than other intersections, but accidents can still happen
  • Be aware that other road users may not use the roundabout correctly
  • Be careful when exiting the roundabout and changing lanes
  • Watch for vehicles making a full turn
  • Look for easy-to-miss objects like bicycles and motorcycles
  • Look for long vehicles that may require extra space
