What does a roundabout signify at an intersection?

A roundabout at an intersection is designed to improve traffic flow and safety. The correct answer emphasizes that drivers must yield to traffic already in the roundabout before entering. This means that vehicles that are circulating in the roundabout have the right of way, which helps prevent collisions and keeps the traffic moving more efficiently.

Yielding is important because it allows for a smoother transition into the roundabout and reduces the likelihood of accidents occurring at the point of entry. By adhering to this rule, drivers contribute to a safer driving environment for everyone on the road.

Other responses suggest inappropriate actions at a roundabout, such as stopping before entrance or driving in the opposite direction, which can lead to confusion and danger. Additionally, proceeding without yielding can disrupt the flow of traffic and increase the risk of collisions. Therefore, understanding the yield requirement at roundabouts is crucial for safe and effective navigation through these intersections.
