Where are U-turns generally prohibited?

U-turns are generally prohibited on curves or near the crest of a hill due to safety concerns. These areas restrict visibility, making it difficult for drivers to see approaching vehicles or obstacles. When executing a U-turn in these locations, a driver may not have adequate time to react if another vehicle is coming, increasing the risk of collisions. Furthermore, such maneuvers can be particularly hazardous in areas where road conditions can change rapidly, or where other drivers may not expect a U-turn to occur.

In contrast, while U-turns may also be restricted in other scenarios, such as at intersections without traffic signs or in certain parking lots, these prohibitions are often less severe than the risks associated with performing a U-turn on curves or hills. The core safety principle guiding this rule emphasizes the need for clear visibility and sufficient reaction time when making turning maneuvers.
