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

Answer: B — U-turns are prohibited at that intersection

A "No U-Turn" sign clearly indicates that making a U-turn at that particular intersection is not permitted. This is put in place to enhance safety, reduce possible accidents, and maintain the flow of traffic. Such a regulation is often necessary at busy intersections or areas where visibility is limited, to prevent hazardous maneuvers that could lead to collisions. In places where this sign is posted, drivers are expected to continue straight or turn right or left, as indicated by other signs or signal controls, instead of attempting to make a U-turn which could endanger themselves or other road users. Understanding the significance of this sign is crucial for safe driving practices and complying with traffic regulations.
