What should be your priority when approaching a roundabout?

Yielding to traffic already in the roundabout is crucial when approaching a roundabout. This practice ensures that vehicles already circulating within the roundabout have the right of way, helping to maintain a smooth flow of traffic and reduce the risk of collisions. Roundabouts are designed to improve traffic efficiency and safety by minimizing points of conflict; therefore, giving priority to those already in the roundabout supports their intended function and assists in preventing accidents.

While signaling your intentions is important for communicating with other drivers, it should come secondary to yielding. Speeding up to merge quickly can lead to dangerous situations and disrupt the orderly flow, making it essential to approach with caution instead. Stopping before entering is generally unnecessary if the roundabout is clear, as it could cause unnecessary delays and congestion. Thus, yielding to existing traffic is the appropriate and safest action when encountering a roundabout.
