Both single-lane and multi-lane roundabouts have begun springing up in WA State over the last decade. They are hailed as a way to reduce accidents at intersections and keep the flow of traffic moving more efficiently.
While roundabouts come in many different shapes and sizes, they have the following traits in common:
- Drivers must yield to traffic in the roundabout (entry yield control)
- Reduced speed inside the roundabout, usually 15-25 mph
- Counter-clockwise flow around a center island
