How should traffic flow in a roundabout?

Traffic in a roundabout is designed to flow counterclockwise around a central island. This counterclockwise movement provides a consistent and predictable traffic pattern, which is essential for reducing confusion and potential collisions among vehicles and cyclists. By following this direction, drivers can gain clear visual cues about upcoming exits and the positioning of other vehicles.

This design also facilitates the merging and exiting of traffic, as vehicles yield to those already circulating within the roundabout, thereby improving overall safety and efficiency. In many regions, including Connecticut, counterclockwise flow is a standardized approach that aligns with the norms of driving on the right side of the road.

The other directions of traffic flow, such as clockwise or in any direction, would create disorganization and could significantly increase the risk of accidents. Moving only to the right would not accommodate multiple lanes or allow for the necessary exits, which are integral features of roundabout design.
