When entering a roundabout, to which vehicles must you yield?

• A. Pedestrians only.
• B. Vehicles waiting at the entrance but not yet in the circle.
• C. Vehicles in the circle after you enter.
• D. Vehicles already in the circle.

Answer: (B)

Roundabouts are designed so the traffic already inside the circle has the right of way. When you approach and are about to enter, you must slow down and yield to vehicles that are already circulating in the roundabout, as well as to any pedestrians crossing at the entrances or exits. You only merge when there is a safe gap. The idea behind the option describing yielding to vehicles waiting at the entrance isn’t aligned with how roundabouts are prioritized, because those waiting to enter aren’t in the circle yet and don’t have priority over vehicles already circulating. Prioritizing the traffic inside the circle keeps the flow smooth and avoids forcing those inside to slow down or stop.
