When is a U-turn legal?

A U-turn is legal on a highway with a paved opening for a turn because these designated areas are specifically designed to accommodate such maneuvers safely. These openings reduce risks associated with making a U-turn in traffic, as they allow drivers to execute the turn without obstructing the flow of vehicles on the highway.

When evaluating other options, making U-turns at any intersection is not always permitted due to traffic regulations and safety concerns. Similarly, limiting U-turns to stop sign locations does not align with legal road use as it may not consider the safety implications of such turns in areas with other traffic and potential hazards. Lastly, while U-turns in residential areas may be allowed in certain circumstances, they can still pose risks due to varying traffic conditions and should be approached with caution.
