Which signs control traffic in a roundabout?

• A. Do Not Enter
• B. Stop signs
• C. Yield and One Way signs
• D. Warning signs

Answer: (C)

The signs that control traffic in a roundabout are the ones that tell you how to enter and how to move once inside. Yield signs at each entrance signal you to slow down and give the right of way to vehicles already circulating in the circle. Inside the roundabout, One Way signs indicate that traffic travels in a single direction around the central island, so everyone moves the same way and conflicts are reduced. Together, these signs manage when you can enter and which way you must travel, keeping the flow smooth and safe. Do Not Enter is used to block an entry, Stop signs would force a full stop at the roundabout entry—which rounds typically don’t require—and Warning signs only alert you that a roundabout is ahead but don’t regulate entry or direction.
