Do not make a U-turn on a curve or near the top of a hill if you cannot be seen by drivers approaching from either direction.

• A. You cannot be seen by drivers approaching from either direction.
• B. There is a sign prohibiting a U-turn.
• C. It is nighttime.
• D. There is a curve ahead.

Answer: (A)

Not being visible to drivers approaching from both directions creates a hazardous situation for a U-turn. If other motorists can’t see you, they won’t expect you to be there and a collision is more likely as you try to turn around. That’s why the rule emphasizes the lack of visibility: you should not perform a U-turn in this spot because it cannot be safely seen by oncoming traffic. The other options point to signs, time of day, or road shape, but they don’t address the core safety issue of being invisible to others.
