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

The correct answer is that vehicles already in the roundabout have the right of way. This is a fundamental rule for navigating roundabouts, designed to facilitate smooth traffic flow and enhance safety. When you approach a roundabout, you must yield to any traffic that is currently circulating within it. This prevents accidents and ensures that vehicles do not have to stop suddenly, which can lead to confusion and potential crashes.

By allowing vehicles already in the roundabout to proceed, the design encourages a continuous flow of traffic. It helps to limit delays and keeps the roundabout operating efficiently. Understanding this right of way rule is essential for safe driving behavior in such areas, especially since roundabouts can often be unfamiliar to drivers accustomed to traditional intersections.

The other choices, which suggest that vehicles entering the roundabout or those based on size or speed have the right of way, do not align with standard traffic laws regarding roundabout navigation. This understanding will help drivers make better decisions and anticipate the actions of other road users in these unique traffic environments.
