Choosing Your Lane

Choose your Lane and Signal

Just like a traditional intersection, you need to be in the correct lane, and signal the direction you are traveling whether you're turning right, left or going straight through. But, unlike traditional intersections, when you exit a roundabout you need to signal right to indicate you're exiting. 

To keep traffic flowing, roundabouts are designed so that lane changes aren't required once you're in the roundabout. 

Turning right in a two-lane roundabout: 

  1. Enter from the right lane.
  2. Signal right as you approach the roundabout in the right-hand lane.
  3. Maintain your signal through the roundabout and stay in the right-hand lane. Travel in the outer lane of the roundabout.
  4. Exit directly from the right lane. 

Going straight through a two-lane roundabout: 

  1. Unless otherwise marked, enter from either the left or the right lane. You don't need to signal when entering the intersection.
  2. Stay in this lane until you exit the roundabout. Signal right prior to your exit.
  3. Exit directly from the lane you are in. 

Turning left in a two-lane roundabout: 

  1. Enter from the left lane.
  2. Signal left as you approach the roundabout from the left-hand lane.
  3. Maintain your signal through the roundabout and stay in the inner lane of the roundabout.
  4. Exit directly from the inner lane. Signal right prior to your exit. 

If you need to make a full circle (u-turn): 

  1. Signal left as you approach the roundabout in the left-hand lane.
  2. Maintain your signal through the roundabout and stay in the left-hand lane.
  3. Signal right prior to your exit, and exit in the left-hand lane. 

These are the general rules for two-lane roundabouts, but it's important to always follow the lane designation signs and pavements markings as each roundabout can be a bit different. 

For example, the roundabouts at 67 Street and 30 Avenue and 67 and Orr/Johnston Drive have dedicated right turn lanes, meaning you don't have to enter the roundabout. Simply signal right, follow the right-turn lane and merge with traffic exiting the roundabout. 

These roundabouts also have a unique feature called spiral lane markings, which are used to accommodate the double turning lanes. While modern roundabouts are designed so that lane changes are not required once you are in the roundabout, the spiral lane markings will guide you from the inside lane to the outside lane in some cases - when you do this you are not crossing lane markings, and thus not making a lane change. This makes it extremely important for drivers entering the roundabout to yield to all lanes of traffic already in the roundabout.  

Specifically this occurs when:
