When should you enter a roundabout?

• A. When there is an adequate gap in traffic
• B. After stopping at the entrance
• C. After the roundabout signals you
• D. When you are in the right-most lane

Answer: (A)

Entering a roundabout safely means waiting for a safe gap in traffic and then merging smoothly. You slow as you approach, yield to vehicles already circulating (and to those approaching from your left if they’re close enough to be in the circle), and only go when there’s enough space to enter without forcing others to brake or swerve. That’s why the best rule is to enter when there is an adequate gap in traffic. Stopping at the entrance usually blocks the flow and isn’t needed if a clear gap isn’t available, and roundabout signals aren’t what determines entry in most situations. The lane you’re in helps you choose your exit, not the moment you may enter.
