What should you do before entering a roundabout?

Before entering a roundabout, the correct action is to yield to traffic already in the roundabout. This is essential for maintaining a smooth flow of traffic and ensuring safety for all vehicles and pedestrians. Roundabouts are designed to improve efficiency by allowing vehicles to flow continuously, rather than stopping at a traditional intersection. By yielding, you ensure that you only enter the roundabout when it is safe, reducing the risk of collisions with vehicles already circulating within it.

Stopping completely might seem prudent but isn’t generally required unless there are specific circumstances, such as a stop sign before the roundabout or pedestrian crossings. Accelerating quickly could lead to dangerous situations, as it may not provide sufficient time to assess incoming traffic. Turning on your left turn signal is not necessary until you are preparing to exit the roundabout, as it can confuse other drivers about your intent while entering. Yielding to the traffic already in place is the most appropriate action ensuring all users of the roadway can navigate safely and efficiently.
