What direction do vehicles travel in a roundabout?

In a roundabout, vehicles travel in a counter-clockwise direction. This design is essential for maintaining a steady flow of traffic and enhancing safety. By having all vehicles circulate in the same direction, it minimizes the risk of head-on collisions and makes it easier for drivers to understand which way to yield and merge.

Counter-clockwise movement allows vehicles entering the roundabout to yield to those already circulating within it, which helps to prevent confusion and promotes orderly traffic flow. Additionally, this counter-clockwise circulation aligns with the typical orientation of traffic signs and markings in the United States, further aiding driver comprehension when navigating through the roundabout.
