What does "no u-turn" signage represent?

The "no u-turn" signage indicates that u-turns are prohibited at that particular location. This means drivers must not make a complete turn to go in the opposite direction, ensuring the flow of traffic is maintained and reducing the risk of accidents. Such restrictions are often placed on busy roads, intersections, or areas where visibility or traffic patterns may render u-turns unsafe.

The other options might suggest various conditions or allowances for u-turns, which contradict the purpose of the "no u-turn" sign. The sign clearly specifies that under no circumstances should a driver perform a u-turn in that area, enhancing safety and compliance with traffic regulations.
