Roundabouts are another way of assigning right-of-way at intersections. They are proven to be safer than traffic signals with reductions in both the frequency and severity of collisions.
Other benefits to installing roundabouts, include:
- improving safety for all road users – pedestrians, cyclists and motorists
- reducing speed, which results in reduced number and severity of crashes
- reducing traffic noise and vehicle emissions
- enhancing appearance of intersection
- lower construction and maintenance costs compared to traffic lights
Using a Roundabout
In a roundabout, traffic flows in a counter-clockwise direction around a centre island. Drivers don't have to stop before entering a roundabout unless there is a vehicle or pedestrian in their way. This way, traffic flows slowly and continuously, in the same direction, and all exits are right turns.
To use a roundabout safely, remember:
- When your car approaches a roundabout, slow down and watch for pedestrians. If there are any pedestrians at the cross-walk, wait for them to cross.
- Wait for a safe gap in traffic already in the circle before you enter the circle.
- Traffic inside the roundabout has the right-of-way, and vehicles entering the roundabout must yield. That means that when you are in the roundabout, do not stop to let other vehicles enter.
- Follow the traffic signs and road markings, and signal before choosing your exit.
- As you exit, watch for pedestrians. If there are any pedestrians at the cross-walk, wait for them to cross.
Your turn signal will let drivers behind you know your planned route, and advise those waiting to enter the circle. Here are guidelines on turn signal use in roundabouts:
- If turning right, signal right on your approach to the roundabout, and continuously signal right until the right turn is complete.
- If driving straight through, you don’t need to signal when entering the roundabout but use a right-hand signal when exiting.
- If turning left, signal left on approach to the roundabout, and continuously signal left until approaching the exit. Signal right to exit.
Cyclists
To protect cyclists’ safety, cycling lanes do not continue through roundabouts, as per engineering design standards.
When approaching the roundabout, cyclists have two options:
- Merge into the traffic lane and proceed in line with vehicles.
- Exit at the off-ramp where the cycling lane closes, dismount, and proceed via sidewalk and crosswalks to reconnect on the other side. Signage will direct cyclists to the off-roadway route.
Emergency Vehicles
In a roundabout, emergency vehicles always have the right-of-way. If you see an emergency vehicle before you enter the roundabout, pull to the right and stop to let the emergency vehicle use the roundabout. If you are in the roundabout, take the nearest exit, then pull to the right and let the emergency vehicle pass you.
