You approach the yield line of a roundabout while a vehicle is already circulating from your left. What should you do?
A two-lane roundabout. Blue A approaches from the left. Silver B is already circulating. YIELD signs control the entries.
Correct answer: Yield and enter only when a safe gap is available.
Why
Slow on approach and yield to crossing users before reaching the entry. Yield to circulating traffic, then enter a safe gap and travel counterclockwise. Do not stop inside merely to admit another entering driver.
