What is the correct action to take when arriving at a roundabout?

When approaching a roundabout, the correct action is to yield to the traffic that is already circulating within the roundabout. This is a key part of ensuring both safe and efficient movement through the roundabout. Traffic within the roundabout has the right of way, meaning that vehicles entering need to wait for a safe gap in the circulating traffic before proceeding.

This approach not only facilitates smooth traffic flow but also minimizes the risk of collisions that can occur if a driver enters the roundabout without yielding. In busy areas, failing to yield creates potential hazards, leading to confusion and accidents.

While it is important to signal when exiting the roundabout to inform other drivers of your intentions, signaling before entering is not generally required or beneficial. Stopping before the roundabout is unnecessary if there are no vehicles approaching, as this can cause delays and disrupt the traffic flow. Therefore, the most crucial and correct action to take when arriving at a roundabout is to yield to the traffic already circulating in it.
