When approached by an emergency vehicle in a roundabout, what should you do?

When you are approached by an emergency vehicle in a roundabout, the appropriate action is to continue navigating the roundabout and exit as normal, then pull to the right. This choice is correct because it allows you to clear the roundabout safely and efficiently, ensuring that you do not obstruct the emergency vehicle while also maintaining the flow of traffic.

Stopping immediately could create a hazardous situation both for you and other drivers, as it could lead to unexpected reactions from vehicles behind you. Changing lanes quickly to exit may not only be unsafe but could also impede the progress of the emergency vehicle. Finally, turning back to avoid the roundabout is not practical, as it could lead to confusion and further traffic issues, as well as potentially blocking the path of the emergency vehicle altogether. Therefore, continuing through the roundabout and then safely pulling to the right to yield allows for a smooth response to the emergency situation while prioritizing safety on the road.
