Final answer:
When driving in adverse weather conditions like rain, snow, or fog, using high beam headlights is not recommended because it can create glare for other drivers, making conditions more dangerous.
Step-by-step explanation:
When driving in adverse weather conditions such as rain, snow, or fog, you should not always use your high beam headlights. The correct answer to the question is 2) No, because it can cause glare for other drivers. High beams can reflect off precipitation and fog, which intensifies the glare and can diminish the visibility for both the driver using the high beams and other drivers on the road. In light rain, oil and gasoline on the road can create slippery conditions, reducing vehicle control, and the glare from high beams can exacerbate this danger. In heavy rain, visibility is already reduced, and the high beams can make it worse, so it's recommended to use low beams in such conditions.
