What does a no U-turn sign indicate?

A no U-turn sign indicates that making a U-turn is prohibited at that location. This sign is implemented to enhance safety and maintain smooth traffic flow. U-turns can create confusion and hazards for other drivers, especially in areas with high traffic volume, intersections, or near pedestrian zones. By signaling that U-turns are not permitted, the sign helps prevent potential accidents and encourages drivers to choose safer, alternative routes for turning around.
