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

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

A "No U-Turn" sign indicates that U-turns are prohibited at that specific location. This regulation is put in place for various safety and traffic flow reasons. It often appears in areas with heavy traffic, complex intersections, or places where visibility is poor, making U-turns potentially dangerous. The sign helps prevent accidents and ensures that vehicles maintain a smooth flow on the roadway without the disruption that U-turns can cause. By adhering to this signage, drivers are reminded to find alternative routes if they need to reverse direction rather than attempting a U-turn where it is not permitted.
