When approaching a roundabout, what should you do?

When approaching a roundabout, yielding to traffic already in the roundabout is the correct action to take. This is essential because vehicles already circulating within the roundabout have the right of way, and yielding allows for a smooth flow of traffic. The design of roundabouts is intended to minimize the likelihood of collisions by promoting continuous movement; therefore, giving priority to existing traffic aids in achieving that goal.

This yielding procedure is a foundational principle of roundabout navigation, as it helps prevent traffic congestion and enhances safety for all road users, including pedestrians and cyclists. Understanding this behavior is crucial for efficient roundabout operation and for maintaining a safe driving environment. In contrast, the aforementioned incorrect options involve actions that either disrupt the flow of traffic or misinterpret the rules governing roundabout use, leading to increased risk of accidents or delays.
