What is the correct action when entering a roundabout?

• A. Yield to traffic in the circle.
• B. Stop at the entrance and wait for a green light.
• C. Enter as soon as you reach the circle.
• D. Accelerate to merge before other vehicles.

Answer: (A)

The action being tested is the basic rule of roundabouts: yield to traffic already in the circle. When you approach, slow down and look to see who is already circulating, including pedestrians at crossings and anyone on bicycles. Enter only when there is a safe gap and you can do so without interrupting or forcing others to brake. Once inside, keep moving with traffic and signal when you plan to exit. That’s why stopping at the entrance until a green light isn’t correct here—roundabouts are designed to be navigated by yielding at the entry, not by waiting for a signal. Entering as soon as you reach the circle ignores the need to wait for a safe gap, and accelerating to merge ahead of others can surprise drivers already in the roundabout.
