What is the minimum distance required to see a U-turn before making one?

The minimum distance required to see a U-turn before making one is 500 feet. This distance is important because it ensures that when a driver is preparing to make a U-turn, they have ample time to spot oncoming traffic, pedestrians, and any potential hazards. By being able to see 500 feet ahead, drivers can make a more informed decision about whether the U-turn can be executed safely, thus reducing the likelihood of accidents and promoting safer road behavior. This distance is established based on the general reaction times of drivers and the need for a clear view of the road to facilitate safe maneuvers.
