What is the recommended action when approaching a roundabout?

When approaching a roundabout, yielding to traffic that is already in the roundabout is the recommended action. This is crucial because roundabouts are designed to facilitate a steady flow of traffic while reducing the likelihood of collisions. By yielding, you ensure that you give the right-of-way to vehicles circulating within the roundabout, allowing them to proceed without interruption.

Observing this rule not only maintains safety but also helps prevent bottlenecks and delays that can occur if drivers enter the roundabout without yielding. It's important to note that roundabouts work by allowing vehicles to merge into the flow smoothly, which is only possible if entering vehicles give way to those already traveling in the roundabout. Hence, understanding the proper yielding practices is fundamental to navigating roundabouts safely and efficiently.
