When is it permissible to make a U-turn on a hill?

• A. If you can see 500 ft or further
• B. If you can see 750 ft or further
• C. If visibility is less than 1000 ft
• D. If it is at least a two-lane road

Answer: (B)

Making a U-turn on a hill is subject to specific visibility requirements to ensure the safety of all road users. The correct choice emphasizes that it is permissible to make a U-turn if you can see 750 feet or further. This distance is significant because it provides ample space for both the driver making the turn and any oncoming traffic to react appropriately. If a driver can see 750 feet ahead, they would typically have enough time and space to execute the maneuver safely, thus minimizing the risk of accidents.

The other options reflect different visibility scenarios that may not meet the safety requirements associated with making a U-turn on a hill. For instance, making a U-turn with visibility less than 750 feet can increase the likelihood of not seeing oncoming vehicles until it is too late, and thus poses a danger to the driver and other road users. Additionally, the road width is less related to the safety of a U-turn on a hill than the visibility distance, making it important to prioritize adequate sight distance over other factors.
