You come to a roundabout. A YIELD sign faces you at the entry, and a car is already driving around the center island toward your entry. What should you do?

Correct answer: Yield to that car, then enter to the right and go counterclockwise.

Why

A roundabout is an intersection, so the yield-sign rule applies at each entry: slow down, stop if necessary, and let vehicles and pedestrians in the intersection go first. Enter only when there is a safe gap in the circulating traffic. Oklahoma law requires every vehicle to go counterclockwise around the central island, so you always turn right to enter. Watch for pedestrians in the crosswalks at the entry and at your exit.
