Where would you typically find Sign CC9?

Sign CC9, which is known as the "Yield Control" sign, is typically placed at traffic circles. Its purpose is to inform drivers that they must yield to vehicles already circulating within the traffic circle or those approaching from the left. This is crucial for ensuring a smooth flow of traffic and preventing collisions, as traffic circles require a specific right-of-way policy that differs from traditional intersections.

In traffic circles, the yield sign clearly indicates that drivers should slow down and prepare to stop if necessary, allowing other vehicles to pass. The clarity of this sign's placement helps manage the unique traffic flow characteristics found in circular intersections, distinguishing it from signage at other locations like pedestrian crossings or stop signs, where different rules apply regarding right of way.
