What should you do when approaching a roundabout?

Answer: B — Yield to traffic already in the roundabout

When approaching a roundabout, it is crucial to yield to traffic that is already in the roundabout. This practice ensures a smooth flow of traffic and helps maintain safety for all road users. Roundabouts are designed to allow continuous traffic movement, so vehicles inside have the right of way. By yielding, you allow those vehicles to pass, minimizing the risk of collisions and reducing delays. Entering the roundabout without yielding can create dangerous situations, as it may force vehicles already circulating to brake or maneuver unexpectedly. Similarly, stopping and waiting for all vehicles to clear could lead to congestion and disrupt the flow of traffic, which is counterproductive to the purpose of a roundabout. Ultimately, yielding to traffic allows for safer and more efficient navigation through these intersections.
