When rain, snow, or fog reduces daytime visibility, which headlights should you use?
Correct answer: B – Low-beam headlights
Rhode Island requires vehicle lights when windshield wipers are being used because of unfavorable weather and whenever visibility is insufficient to see clearly for 500 feet. The driver’s manual directs motorists to use low beams during rain, snow, fog, and other conditions that reduce visibility. High beams may reflect from the precipitation and shorten the driver’s effective viewing distance.
