What should you do if you approach a roundabout?

When approaching a roundabout, yielding to traffic already in the roundabout is essential for safe and efficient navigation. Traffic inside the roundabout has the right of way, allowing for a continuous flow of vehicles and minimizing delays. By yielding, you ensure that you are not disrupting the movement of cars already circulating, which helps prevent crashes and maintains orderly traffic patterns.

It is also important to note that speeding up to enter quickly can create a hazardous situation, as you may enter the roundabout at an inappropriate time, increasing the risk of collision. Stopping before entering is unnecessary unless it is unsafe to proceed, as this could disrupt the flow of traffic. Turning around may confuse other drivers and is not a valid maneuver unless directed to do so. Thus, yielding is the most appropriate action to take when navigating a roundabout.
