In a roundabout, vehicles that are already within the circle have the right of way. This is a key principle designed to improve traffic flow and safety. When vehicles enter a roundabout, they must yield to those already circulating, which helps reduce the risk of collisions and keeps traffic moving smoothly.

Understanding this rule is crucial for both drivers and pedestrians. It encourages drivers to adapt to the traffic patterns in roundabouts, which differ from traditional intersections where traffic lights or stop signs may dictate right of way. Vehicles in the roundabout have established their path and should not be interrupted by those entering.

While pedestrians and bicyclists also have specific rules and rights concerning their movement, in the context of vehicular traffic specifically within the roundabout, those already in the circle take precedence.
