What does a no U-turn sign mean?

Answer: B — Making a U-turn at that location is prohibited

A no U-turn sign indicates that making a U-turn at that specific location is prohibited. This traffic sign is essential for maintaining safety and smooth traffic flow, especially in areas where executing a U-turn could pose risks to drivers and pedestrians or create congestion. This prohibition usually exists in places where visibility is limited, where the roadway is too narrow for such maneuvers, or where it might cause confusion among other road users. By adhering to this sign, drivers contribute to safer road conditions and help prevent potential accidents. Understanding this regulation is pivotal for any driver to ensure compliance with traffic laws and enhance overall road safety.
