Final answer:
Using high beam lights in foggy, rainy, or snowy conditions can reduce visibility due to glare. Drivers should use low beam lights or fog lights instead.
Step-by-step explanation:
Using high beam lights when it is foggy, raining, or snowing is not recommended because it can create glare and reduce visibility. The high beams reflect off the water particles in the air and can make it even harder to see. Instead, drivers should use low beam lights or fog lights if their vehicle is equipped with them.
