What is a Roundabout?

The modern roundabout is an intersection designed to control traffic in a circular flow. It is economical and reduces overall traffic delays. Traffic moves in a counter-clockwise direction around a central island. Emergency vehicles can quickly and safely pass through roundabouts and noise pollution is decreased as well.

How to Get Around

As drivers approach a roundabout, they slow down and must yield to traffic in the roundabout. When a gap in traffic is available on the left, drivers enter the roundabout by turning right and then travel around until they reach their exit point.



At roundabouts, signs like those shown to the right will be used to direct traffic. Yield signs at the entrance to the roundabout will show drivers that vehicles in the roundabout have the right-of-way.

General Rules for Driving a Roundabout

  • Pick The Correct Lane before entering the roundabout, never change lanes when inside the roundabout
  • Slow Down and watch for traffic signs
  • Yield to pedestrians and bicyclists as you enter and exit the roundabout
  • Look to the left for traffic and enter when it is safe
  • Signal and exit to your destination - not signaling could cost you a $115 fine and demerits

Pedestrians & Roundabouts

Roundabouts are designed to accommodate pedestrians. Drivers should watch for pedestrians wanting to cross both before they enter the roundabouts as well as at their exit point.

Cyclists & Roundabouts

Cyclists can either ride inside a roundabout or dismount and walk their bicycle across the crosswalk. Experienced riders may choose to cycle, but must follow the same rules as vehicles. Since traffic is slower inside the roundabout, cyclists should be able to travel at or near the same speed as motorists, staying in line with the circulating traffic.

Trucks & Roundabouts

Lethbridge roundabouts are designed to handle all large truck turning movements. The apron around the raised centre island provides extra space for the trailing wheels of large trucks while driving around the roundabout.

Safety of Roundabouts

Roundabouts are proving to be much safer than standard intersections. Statistics show that roundabouts reduce fatal and injury collisions by an average of about 75%. They are safer due to slower speeds and reduced conflict points - spots where vehicles may collide with each other or with pedestrians.
