When approaching a roundabout, yielding to traffic already in the roundabout is essential for ensuring safe and efficient navigation. Roundabouts are designed to keep traffic flowing smoothly, and vehicles that are already in the roundabout have the right of way. By yielding to these vehicles, you help prevent accidents and ensure that the flow of traffic is maintained.

Entering at any time can lead to collisions, especially if you do not check for ongoing traffic. Speeding up to merge quickly can also create unsafe situations, as it may not leave enough time to assess gaps in traffic. Stopping before entering the roundabout is generally unnecessary unless there are specific signage or other conditions that require it. Thus, yielding to traffic already in the roundabout is the most appropriate and safest action when approaching a roundabout.
