What should you do when approaching a roundabout?

Answer: B — Yield to vehicles already in the roundabout and signal your exit

When approaching a roundabout, it is essential to yield to vehicles that are already in the roundabout and signal your exit. This practice enhances safety and ensures smooth traffic flow. By yielding, you allow vehicles that are already in the roundabout to pass before you enter, helping to prevent collisions and ensuring that you do not disrupt the traffic patterns established by other vehicles. Signaling your exit is equally important, as it communicates your intentions to other road users, warning them that you are about to leave the roundabout. This aspect of communication helps to maintain safety and predictability on the road, which is particularly vital in a multi-vehicle environment like a roundabout. Other actions, such as accelerating to enter quickly, checking your phone for directions, or reversing if you miss your exit, can lead to dangerous situations and are not in line with safe road practices.
