When entering a roundabout, who has the right of way?

Answer: A — Vehicles already in the roundabout

Vehicles already in the roundabout have the right of way. This rule is established to maintain a smooth flow of traffic and minimize potential accidents. The design of roundabouts is intended to allow vehicles that are already circulating to continue moving without having to stop for those that are entering. Therefore, as a driver approaching a roundabout, it is essential to yield to traffic that is already within the circular intersection, ensuring safe and efficient passage for all road users. Understanding this right of way is crucial for both drivers and pedestrians, as it affects their movements and the overall safety within the roundabout.
