What action should you take when approaching a roundabout?

Answer: B — Yield to traffic already in the roundabout

Yielding to traffic already in the roundabout is essential because it helps to ensure a smooth flow of vehicles within the intersection. Roundabouts are designed to allow traffic to flow continuously, reducing the need for stops and minimizing the chance of accidents. By yielding to vehicles that are already circulating in the roundabout, you are respecting their right of way and helping maintain the orderly movement of traffic. This practice reduces the likelihood of collisions, ensures that drivers can navigate the roundabout safely, and ultimately promotes a more efficient traffic pattern. Understanding this concept is vital for all drivers, as it contributes to safer driving conditions in areas where roundabouts are used.
