What does a no U-turn sign signify?

A no U-turn sign signifies that making a U-turn at that intersection is prohibited. This restriction is often implemented in areas where a U-turn could pose safety hazards, such as high-traffic intersections, curves in the road, or areas with limited visibility. By indicating that U-turns are not allowed, the sign helps maintain smoother traffic flow and reduces the likelihood of accidents. Understanding the implications of such a sign is essential for all drivers to ensure compliance with traffic regulations and promote road safety.
