Roundabouts are increasingly common across Ontario, appearing in major urban centers like Ottawa (e.g., Huntmar Drive in Kanata), Kingston (Taylor-Kidd Blvd), Waterloo Region (Franklin Blvd), and new Greater Toronto Area (GTA) developments. Designed to improve traffic flow and reduce severe collisions, roundabouts can feel intimidating to new drivers.

Understanding how to drive a roundabout ontario rules ensures you navigate single-lane and multi-lane intersections smoothly and safely.

Fundamental Roundabout Rules in Ontario

Understanding who has the right of way in a roundabout comes down to one absolute rule under the Ontario Highway Traffic Act (HTA): traffic already inside the roundabout always has the right of way.

Step-by-Step Guide: Navigating Single & Multi-Lane Roundabouts

1. Approaching the Roundabout

As you approach, pay attention to yellow lane-guidance signs. In a multi-lane roundabout, you must select your lane before entering:

  • Left Lane: Use if you plan to turn left, make a U-turn, or go straight.

  • Right Lane: Use if you plan to turn right or go straight.

2. Yielding at the Entry Line

Slow down and yield to pedestrians crossing at the splitter island crosswalk. Look to your left. Wait for a safe gap in circulating traffic before entering. Do not stop inside the roundabout if traffic is clear.

3. Driving Inside the Roundabout

Once inside, circulate counter-clockwise. Never change lanes or attempt to pass another vehicle while inside a roundabout.

4. Exiting the Roundabout

As you pass the exit before the one you want, activate your right turn signal. This alerts drivers waiting to enter that you are exiting. Yield to pedestrians crossing the exit lane as you pull out.

Handling Large Trucks, Pedestrians, and Emergency Vehicles

  • Large Commercial Trucks: Semi-trucks require extra space and may use both lanes to navigate the central apron. Never attempt to drive alongside or pass a large truck inside a roundabout.

  • Pedestrians & Cyclists: Pedestrians have priority at designated entry and exit crosswalks. Cyclists may choose to ride in the center of the lane like a motor vehicle or dismount and use pedestrian crosswalks.

  • Emergency Vehicles: If an emergency vehicle approaches while you are outside the roundabout, pull over to the right before entering. If you are already inside, complete your exit first, then pull over to the right.
