Circular Intersection sign
A roundabout or other circular intersection is ahead.
What to do
Slow down, be ready to yield to traffic in the circle, and travel counterclockwise.
Slow down, pick your lane early, and be ready to yield to traffic already circulating before you enter to the right.
Where it's used
Section 2C.41 allows the Circular Intersection (W2-6) sign in advance of a roundabout or other circular intersection, and says it should be used when the approach has a speed limit of 40 mph or more. It is a black-on-yellow diamond with three curved arrows forming a circle in the counterclockwise direction of travel. An educational plaque such as ROUNDABOUT (W16-12aP) or TRAFFIC CIRCLE (W16-12P) may be mounted below it.
Don't confuse it with
- Roundabout Circulation plaque: The Roundabout Circulation plaque is a white regulatory plaque at the roundabout entry showing the direction to travel, while the yellow diamond is an advance warning.
- Cross Road: Cross Road warns of an ordinary four-way intersection, not a circular one.
- Yield Ahead: Yield Ahead warns of a YIELD sign ahead, which you will usually also meet at a roundabout entry, but it does not show the circular layout.
