What is a roundabout?

A roundabout is best defined as a circular intersection control device with traffic circulating around a central island. This design facilitates the smooth flow of traffic by allowing vehicles to enter and exit at various points without the need for traffic signals or stop signs. The central island typically serves as a visual and physical barrier, which not only helps to guide vehicles through the intersection but also enhances safety by slowing down traffic speeds.

In a roundabout, vehicles traveling in and out are required to yield to traffic already circulating, which helps minimize conflicts and reduce the likelihood of collisions compared to traditional intersections. This design encourages continuous movement, thereby improving the efficiency of traffic flow, making it an effective solution for managing traffic at busy intersections.

Understanding the function and structure of roundabouts is crucial for drivers to navigate them safely and confidently, emphasizing the importance of yielding to circulating traffic and recognizing that roundabouts can be a more efficient alternative to standard intersections.
