When making a U-turn, what should you avoid?

When making a U-turn, it is important to avoid making the turn on a curve in the road or near a hill because visibility can be significantly reduced in these areas. Curved roads and hills can obstruct the sightlines of both the driver making the U-turn and other motorists approaching from different directions. This lack of visibility increases the risk of a collision, as the driver may not see oncoming traffic until it is too late. Therefore, choosing a location that provides clear visibility in all directions is crucial for safety when executing a U-turn.
