What does a No U-turn sign mean?

• A. U-turns are prohibited at that location.
• B. U-turns are allowed at that location.
• C. You may U-turn after you stop.
• D. U-turns are allowed during daylight.

Answer: (B)

A No U-turn sign means you cannot reverse direction by making a U-turn at that spot. It’s a regulatory rule intended to keep traffic flowing safely and prevent crashes where a U-turn could interfere with other vehicles or pedestrians. When you see it, you should continue straight or follow any other permitted turns, and only change direction where a separate sign or signal allows it. The sign’s symbol is usually a U-turn arrow with a red circle and diagonal slash, indicating the prohibition applies regardless of time of day. In short, U-turns are not allowed at that location.
