What is a "rotary"?
A rotary, also known as a traffic circle or roundabout, is a circular intersection where multiple roads meet. Vehicles travel around a central island in a counterclockwise direction, in countries where people drive on the right side of the road, to exit onto one of the connecting roads. This design helps manage traffic flow by reducing the need for stoplights or stop signs, allowing vehicles to keep moving smoothly. Rotaries are often used in busy areas to keep traffic moving and reduce the likelihood of accidents, as they help control speed and eliminate sharp turns.
Example
Drivers yielded to traffic already in the rotary before entering.
She found navigating the rotary confusing at first.
