Approaching:
- Slow down and watch for pedestrians on the approach to the yield line at the entrance of the roundabout. Stay in your lane.
Entering:
- Visual checks: Do visual checks of all vehicles already in the roundabout and those waiting to enter (including cyclists).
- Look left: Traffic in the roundabout has the right-of-way. When preparing to enter the roundabout, pay special attention to the vehicles to your left. Adjust your speed or stop at the yield sign if necessary.
- Adequate gap: Watch for a safe opportunity to enter the roundabout. Enter when there is an adequate gap in the circulating traffic flow. Don't enter directly beside another vehicle already in the roundabout, as that vehicle may be exiting at the next exit.
- Travel counter-clockwise: Once in the roundabout, always keep to the right of the central island and travel in a counter-clockwise direction.
- Keep moving: Once you are in the roundabout, do not stop except to avoid a collision; you have the right-of-way over entering traffic.
- Signal: Always signal lane changes.
Exiting:
- Signal: Be sure to signal your exit and watch for pedestrians.
- Maintain your lane: Stay to the left if you entered from the left lane, or stay to the right if you entered from the right lane.
- Maintain your position: Maintain your position relative to other vehicles.
- Signal intent to exit: Once you have passed the exit before the one you want, use your right-turn signal.
-
Left lane exit: If exiting from the left lane, watch out for vehicles on the right that continue to circulate around the roundabout.

Dealing with particular situations at a roundabout:
Consider large vehicles
Allow extra room alongside large vehicles (trucks and buses). Large vehicles may have to swing wide on the approach or within the roundabout. Give them plenty of room.
Pull over for emergency vehicles
If you are in the roundabout when an emergency vehicle access, take the exit, and intends to continue outside the transport island before pulling over. If you have not entered the roundabout, however, because of the right if possible and wait for the emergency vehicle passed.
Driving a large vehicle in a roundabout
A driver negotiating the roundabout in large vehicles (such as a truck or bus) may have used the full width of the roads, including aprons (a mountable center of the neighboring island of the driveway), if it has been determined. Before entering the roundabout, vehicles may need to take both paths. Give a lot of large vehicles space for maneuver.
