What does a “No U-Turn” sign mean?

A “No U-Turn” sign indicates that making a U-turn at that specific location is prohibited. This means drivers must not attempt to turn their vehicle in a complete circle to go in the opposite direction. The presence of this sign is enforced to ensure safety, as U-turns can create hazards in busy areas, intersections, or where visibility is limited. By following this instruction, drivers help maintain the flow of traffic and reduce the risk of accidents.

Other choices imply conditions under which U-turns may be permitted, which contradicts the clear directive provided by the “No U-Turn” sign.
