What should you do if you miss your exit while approaching a traffic circle?

If you've missed your exit while approaching a traffic circle, the most appropriate action is to continue around the circle until you come back to your desired exit. This approach is safe and ensures that you do not disrupt the flow of traffic or create hazards by making sudden maneuvers.

Continuing around the traffic circle allows you to maintain your speed and position without risking accidents that could occur from stopping suddenly or reversing, which would be illegal and dangerous. It is essential in a traffic circle to maintain awareness of your surroundings while safely waiting for your next opportunity to exit.

The other options suggest actions that could lead to safety concerns. Stopping and backing up is dangerous and can lead to collisions. Driving straight through without considering your exit could lead to missing multiple opportunities and could be confusing for other drivers. Signaling and pulling over immediately can also create hazards for yourself and others, especially if done abruptly. Therefore, the best practice is to keep moving around the circle until you can safely exit.
