Which type of beams should be used when traveling in fog, rain, or snow?

Answer: A — Low

Using low beams while traveling in fog, rain, or snow is the appropriate choice for several critical reasons. Low beams are designed to cast a shorter, wider light on the road, which helps to illuminate the immediate area in front of your vehicle without creating glare. In challenging weather conditions like fog, rain, or snow, high beams can reflect off moisture, creating a blinding effect and further reducing visibility. This can be particularly dangerous, as it can lead to an inability to see both the road and other vehicles clearly. Low beams provide better visibility under these conditions, allowing drivers to see obstacles and road signage while minimizing glare that can impair their vision. Utilizing low beams is a standard recommendation in safe driving practices during inclement weather, contributing significantly to overall road safety.
