A roundabout is a circular intersection designed to improve traffic flow and safety. Instead of stopping at traffic lights or stop signs, vehicles entering the roundabout yield to those already inside. This helps reduce the chances of accidents and keeps cars moving smoothly. Roundabouts often feature landscaping in the center, which can include flowers or sculptures, making them more visually appealing. They are commonly found in many countries, including the United Kingdom and France, and are becoming increasingly popular in the United States as a way to manage busy intersections efficiently.
