You must not turn around on curves and hills unless you can see for at least _______ in all directions.

• A. 100 feet
• B. 200 feet
• C. 1000 feet
• D. 500 feet

Answer: (D)

When you’re on curves or hills, you need enough sight distance to properly judge the road and any approaching traffic before you change direction. The rule says you must be able to see at least 500 feet in all directions before turning around. That amount of visibility gives you time to spot oncoming vehicles, pedestrians, or other hazards and to complete the maneuver safely without forcing others into a risky move.

Shorter distances, like 100 or 200 feet, don’t leave you with enough warning to react if a car or cyclist appears around the bend or over the crest. A distance like 1000 feet isn’t the standard requirement for this situation and isn’t necessary for safety in this context. So, 500 feet is the correct minimum.
