Final answer:
The law requires a driver to have sufficient visibility down the road when making a U-turn near a hill or curve, which typically means being able to see oncoming traffic for a safe distance.
Step-by-step explanation:
When making a U-turn near a hill or curve, the law requires that you be able to see sufficiently down the road to ensure it is safe to perform the maneuver. This specific distance can vary by jurisdiction but is typically a considerable length that allows for a driver to see oncoming traffic and react accordingly to avoid a collision. It's essential for drivers to have enough visibility to complete the turn safely without impeding oncoming vehicles, which may be traveling at high speeds and appear suddenly due to the curve or hill obstructing the view.
When making a U-turn near a hill or curve, the law requires that you be able to see clearly before proceeding. This means that you should have a clear view of any oncoming traffic or potential hazards that may be obstructed by the hill or curve.
