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

A "No U-Turn" sign specifically indicates that making a U-turn is prohibited at that location. This restriction is typically imposed for safety reasons, as U-turns can create hazards for other vehicles and pedestrians in busy areas or where visibility is limited. The sign aims to prevent drivers from executing this maneuver, ensuring smoother traffic flow and reducing the likelihood of accidents.

While other choices might represent different traffic commands or instructions, they do not accurately convey the meaning of the "No U-Turn" sign. For instance, turning left after stopping, exclusively turning right, or being required to go straight could all be legitimate traffic instructions but do not reflect the specific prohibition that the "No U-Turn" sign communicates.
