What Lights to Use When Entering a Roundabout?

[BarrettRose]

Roundabouts are also known as traffic circles in many southern cities. Therefore, many people from the south may not initially understand what a roundabout is when they first arrive in the north. Vehicles do not need to signal when entering a roundabout, but they must use the right turn signal when exiting. This is because entering a roundabout does not affect other vehicles, while the exit point is variable, requiring signaling to indicate the intention. The formal name for a roundabout is "circular intersection," a traffic facility set up at the junction of multiple intersections to reduce vehicle conflicts, mostly circular in shape. Roundabouts allow vehicles to move in the same direction, transforming conflict points into passage points, effectively reducing the occurrence of traffic accidents.
