What does a No U Turn sign indicate?

Answer: A — white rectangle with a U-turn symbol and red outline

A No U Turn sign is designed to clearly communicate that making a U-turn is not permitted at that location. The sign typically features a white rectangle with a U-turn symbol (an arrow that indicates a U-turn) enclosed within a red outline. This design ensures high visibility and clarity for drivers, reinforcing the restriction. The red outline serves as a universal signal for “no” or “prohibited,” guiding drivers to understand that they must find an alternative route instead of performing a U-turn. Other options describe signs that either do not accurately represent the prohibition or convey different meanings altogether. A yellow triangle generally indicates a caution or warning about a potential hazard, while a green sign typically provides information or guidance rather than restrictions. The red circle with a U-turn arrow would imply a prohibition, but it does not align with the standard design of a No U Turn sign, which uses a rectangle format rather than a circular one. Understanding these details can help drivers navigate road rules effectively and recognize various traffic signs.
