Final answer:
To drive through a traffic island, yield to existing traffic in the circle, enter with a gap, avoid stopping inside, stay in your lane, and signal before exiting.
Step-by-step explanation:
When driving through a traffic island, or roundabout, the general rule is to yield to drivers already in the circle. Enter the traffic island when there is a sufficient gap in traffic, and do not stop while inside the roundabout unless it's necessary to avoid an accident. Always stay in your lane and use your turn signal when you intend to exit the roundabout. The traffic inside the circle usually has the right of way, but this can vary by jurisdiction, so local traffic rules should always be respected. If the traffic island has signal lights such as a red blinker indicating stop and a yellow blinker indicating caution, follow those signals appropriately.
