A traffic circle is a central island in the middle of an intersection, where all vehicles must travel to the left of the island. Traffic circles can be small (a mini-circle drawn on the road surface), large (a roundabout with a physical middle section), single-laned or multi-laned. The number of roads that come into a roundabout can range from three to five or even more.

At a traffic circle, you must yield right of way to any traffic approaching from the right, unless there is a road sign or a traffic officer instructing something else. Any vehicles inside the traffic circle that have already crossed any yield line, have right of way for traffic outside the traffic circle. There may be signs at or coming up to traffic circles; these should be adhered at all times.

1. Slow down as you come up to the traffic circle
2. Try to get into the correct lane if there are multiple lanes
3. Give way to all vehicles that will cross your path from your right as you enter the traffic circle

If you are turning left at the first exit of a roundabout, signal left as you come up to the traffic circle.

If you are going 'straight' through a traffic circle:

1. Don't signal as you come up to the roundabout
2. Signal left as you pass the exit before the one you wish to take. At some small roundabouts it may not be possible to give three seconds warning, but it is courteous to give as much indication as you can.

If you are traveling further than the halfway through the traffic circle:

1. Signal right as you come up to the roundabout
2. Signal left as you pass the exit before the one you wish to take.

At roundabouts, look out for vehicles that:

1. May have to change lanes to exit
2. May not be able to stay in their lane because they are large (for example, buses) or traveling too fast.
