When driving in rain, you must:

  1. Use low beam headlights. ✓
  2. Use high beam headlights.
  3. Use parking lights.
  4. Use no lights.

Answer: A. Use low beam headlights.

When driving in rain, you must use low beam headlights.

Why this is the answer

The New York manual says to turn on your headlights when you use your windshield wipers to clear rain, snow, or sleet. It also says parking lights and daytime running lights are not a replacement for headlights. For high beams, the manual says to be considerate and requires low beam when you are close to an oncoming vehicle or one ahead. That supports low beam as the proper headlight setting in rain rather than high beam, parking lights, or no lights.

Why the other answers are wrong

Remember it

If your wipers are on, your headlights should be on, and keep them on low beam around other traffic.
