When approaching a roundabout, what must you do?

When approaching a roundabout, you must yield to traffic already in the roundabout. This is crucial for ensuring the smooth flow of traffic and avoiding collisions. Vehicles inside the roundabout have the right of way, so as a driver entering, you should slow down and assess the traffic situation.

Yielding allows you to merge safely into the roundabout when you have an adequate gap in traffic. This practice helps maintain the efficiency of the roundabout design, which is intended to reduce delays and improve safety compared to traditional intersections.

Stopping completely can lead to unnecessary traffic build-up and impede the flow of traffic, while signaling left is not required when you are approaching a roundabout; instead, you signal when you are exiting. Going around without yielding would create a dangerous situation, possibly leading to accidents with vehicles already in the roundabout. Therefore, yielding is the fundamental rule that ensures safety and efficiency when navigating roundabouts.
