Roundabout Information

What is a roundabout?
Roundabouts are becoming more and more common in countries around the world, from the U.S. and Canada to the Middle East. They’re really just intersections in a circular shape — forcing drivers to go around a central island and making new vehicles that are entering to yield the right-of-way.

Roundabouts help improve traffic flow by allowing drivers to slow down and go around until making a turn instead of stopping and waiting. They can prevent serious crashes involving injuries at intersections because they reduce speeds and virtually eliminate T-bone (right-angle) collisions.

Benefits of roundabouts
On average, there’s 76 per cent fewer injuries/fatalities and 35 per cent fewer collisions in roundabouts.

Other benefits include:
  • slower vehicle speeds
  • improved safety for cyclists and pedestrians
  • reduced greenhouse gas emissions
  • improved aesthetics.
Don’t confuse them with your local neighborhood
traffic circles. There are different rules for drivers
entering and leaving a roundabout.

  3. Tips for Cyclists
When you're approaching the roundabout
Yield to all pedestrians at each approach of the roundabout — if there’s a clearly marked pedestrian crosswalk, it will be located approximately one car length in advance of the yield line. Don’t block the pedestrian crossing.

When you're entering the roundabout
Yield to traffic that is already inside the roundabout, as it has the right-of-way.

When you're circulating in the roundabout

Go counter-clockwise within the lane. The truck apron is typically raised and/or colored, and can be used by large trucks or emergency vehicles to drive over to manoeuvre through the roundabout.

If approached by an emergency vehicle, continue through the roundabout and then pull over once you exit to allow the emergency vehicle to pass.

When you're exiting the roundabout

Signal a right turn just in advance of your exit location so that drivers waiting to enter the roundabout and pedestrians waiting to cross know your intentions.

Exit at desired street.

Yield to pedestrians that may be crossing the exit lane.
