What should you do when approaching a roundabout?

Answer: A — Yield to traffic within the roundabout

When approaching a roundabout, yielding to traffic that is already inside the roundabout is crucial for maintaining safety and ensuring the smooth flow of vehicles. This rule helps prevent collisions and allows drivers who are traveling within the roundabout the right of way, as they are already in the circulating path. Entering a roundabout without yielding can lead to potentially dangerous situations, as it may force drivers already navigating the roundabout to brake unexpectedly or swerve to avoid an accident. Stopping before entering is not required unless there are specific signs indicating that you must come to a halt, but it can disrupt the flow of traffic and cause confusion. Signaling left before entering may not be necessary since you generally shouldn't signal until you are preparing to exit the roundabout. The emphasis is on yielding to ensure everyone can navigate the roundabout safely and efficiently.
