What does a "No U-Turn" sign indicate?

Answer: C — To prohibit making a U-turn at that intersection

A "No U-Turn" sign is an important traffic control device that explicitly indicates drivers are not permitted to make a U-turn at that particular intersection. This prohibition is often put in place for safety reasons, as making a U-turn can be dangerous in areas with high traffic volumes or limited visibility. Drivers are expected to find alternative routes if they need to change direction, ensuring a smoother and safer flow of traffic. Understanding this sign is crucial for compliance with traffic laws and for the safety of all road users.
