Why can't you make a U-turn on white dashed lines?

[SanHarper]

Because making a U-turn on white dashed lines can easily lead to traffic accidents. White dashed lines indicate pedestrian crossings, which are signs for pedestrians to pass through. Here is the relevant information: 1. White dashed lines: When marked on road sections, they are used to separate traffic flows in the same direction or serve as safe driving distance identification lines; when marked at intersections, they are used to guide vehicle movement. 2. Situations where U-turns are allowed: At locations with designated U-turn openings, drivers should turn on the left turn signal in advance and make the U-turn without affecting other normal traffic; at intersections with U-turn signals, ensure the U-turn signal is green and make the U-turn only within the designated lane; at intersections with U-turn signs, make the U-turn based on actual conditions without obstructing other vehicles or pedestrians, and at intersections without explicit prohibitions against U-turns or left turns.
