Driver's Education: U-Turn Safety
When making a U-turn, it is important to avoid doing so on a curve, near the top of a hill, or anywhere you cannot be seen by other drivers. This is because these situations can obstruct the view of other drivers and increase the risk of accidents.
There is no specified distance for how many feet away you should be from these areas before making a U-turn. It is important to use your judgment and ensure that you have enough visibility and space to complete the U-turn safely.
For example, if you are on a curve, you should wait until you have a clear line of sight in both directions before attempting the U-turn.
