When driving on an undivided road, you are prohibited from making a U-turn on a curve or near a hill crest if you are not visible to:
- A.drivers ahead of you.
- B.drivers approaching from either direction.✓
- C.drivers on your right.
- D.drivers stopped on the shoulder.
Why: On undivided roads, you must not make a U-turn on a curve or hill if you aren't visible to traffic coming from both directions. This prevents dangerous collisions with drivers who cannot see you in time to stop.
