The benefits of roundabouts and how to navigate

Many drivers encounter roundabouts on urban roads, especially in Alberta, where they are becoming increasingly popular.

Not to be confused with traffic circles, which typically have two or three lanes and are located at high-volume intersections, a roundabout is an intersection where traffic flows in a counter-clockwise circle around a centre island.

Safety benefits of roundabouts to drivers:

• There are never any left turns in front of oncoming traffic. 
• There are far less chances for serious crashes. 
• The circulating movement of roundabouts nearly eliminates the potential for high-speed, right angle or head-on collisions.
• Rear-end crashes are also often reduced in roundabouts. 

Another benefit is for those who live in an area near a roundabout. Drivers don’t stop in a roundabout so there is far less traffic noise than a normal intersection.

Other advantages of a roundabout

• Effectively and safely slow traffic.
• Improve traffic flow.
• Reduce vehicle emissions and fuel consumption.    

How to safely enter and exit a roundabout

Entering

• When approaching a roundabout, reduce your speed, look well ahead and watch for signs that may help you find your exit.
• Scan for people using the crosswalk, and be prepared to stop.
• Before you enter, yield to traffic that is coming from your immediate left that is already in the roundabout.
• When safe to do so and there is a gap in traffic, enter the roundabout in a counter-clockwise direction and continue until you reach your exit.

Exiting

• Remember that unless traffic conditions require it; never come to a full stop when driving in a roundabout.
• Use your right turn signal to let other road users know where you plan to exit.
• Check the mirrors and your blind spot, then exit at a safe speed.
• As you exit, scan for people using the crosswalk, and be ready to stop.
