What should you do when you approach a roundabout?

Answer: B — Yield to traffic already in the roundabout and signal when exiting

When approaching a roundabout, it is important to yield to any traffic that is already within the roundabout, as they have the right of way. This ensures a smooth flow of traffic and helps to prevent collisions. Additionally, signaling when you exit the roundabout is crucial. It informs other drivers of your intentions, promoting safer driving conditions for everyone. Yielding and signaling is rooted in the fundamental rules of driving etiquette and safety, allowing vehicles to merge seamlessly into the roundabout once it is safe to do so. This approach minimizes confusion and helps maintain order on the road, which is especially important in busy traffic situations.
