What action should a driver take at a roundabout?

When approaching a roundabout, it is essential for drivers to yield to traffic that is already circulating within the roundabout. This is a fundamental rule designed to ensure smooth traffic flow and minimize the risk of collisions. By yielding, you allow those vehicles already in the roundabout the right of way, which helps maintain order and safety.

Additionally, signaling before exiting the roundabout is important as it communicates your intentions to other drivers, ensuring that everyone is aware of where you plan to go. This improves safety by reducing uncertainty among road users.

In contrast, speeding up to enter the roundabout can create dangerous situations, particularly if vehicles are already circulating. Coming to a full stop can disrupt the flow of traffic, making it less efficient, and ignoring road signs can lead to confusion and potential accidents as those signs often provide essential guidance for navigating the roundabout correctly.
