What is the purpose of yield lines at roundabout intersections?

Yield lines at roundabout intersections are specifically designed to help regulate the flow of traffic. They serve as visual cues that indicate where vehicles must yield to others, particularly to those already circulating within the roundabout. This arrangement ensures a smooth transition for vehicles entering the roundabout, minimizing abrupt stops and encouraging a continuous flow of traffic.

By clearly marking the yielding point, yield lines enhance safety by reducing potential conflicts between entering and circulating vehicles. This contributes to a more efficient navigation of the roundabout, promoting a predictable pattern of movement that drivers can easily understand and anticipate. Other options like marking pedestrian crossings or indicating parking areas fall outside the specific role of yield lines and do not relate to the primary function of managing traffic behavior and ensuring orderly traffic flow in a roundabout setting.
