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

When approaching a roundabout, vehicles already in the roundabout have the right of way. This means that drivers must yield to traffic that is circulating within the roundabout before entering. The design of roundabouts is intended to improve traffic flow and safety by allowing vehicles within the roundabout to continue moving without unnecessary stops.

By yielding to the vehicles already in the roundabout, drivers help to maintain a smooth flow of traffic and reduce the likelihood of accidents. This is particularly important because many roundabouts are designed to handle high volumes of traffic in a safe and efficient manner. It's also a common traffic rule in many places, emphasizing the importance of yielding when approaching such intersections.

As for the other options, vehicles entering the roundabout must wait for a gap in traffic before proceeding, making it clear that they do not have the right of way. While larger vehicles can sometimes appear to dominate the space, their size does not grant them preferential treatment regarding right of way. Finally, pedestrians crossing the entrance do have certain protections, but their right of way is typically not prioritized over vehicles already within the roundabout unless specific road signage indicates otherwise.
