When approaching a roundabout, yielding to traffic that is already in the roundabout is crucial for maintaining safety and ensuring smooth traffic flow. Roundabouts are designed to allow continuous movement and reduce collision risks; therefore, vehicles within the roundabout have the right of way. This means that as a driver prepares to enter the roundabout, they should slow down and look for any oncoming traffic that might already be circulating. By yielding, drivers avoid potential accidents and contribute to an efficient traffic pattern.

In contrast, accelerating to merge or stopping completely would interrupt the flow of traffic and could lead to confusion or collisions. Signaling to change lanes is also not relevant in the context of a roundabout since there are no distinct lanes as seen in traditional intersections, and drivers should focus on safely entering the circular roadway.
