Philadelphia Drivers License Practice Test

What type of headlights should you use in fog, snow, or heavy rain?

1. High beam lights

2. Low beam lights

3. Parking lights

4. Fog lights

The correct answer is: Low beam lights

Using low beam lights in fog, snow, or heavy rain is the most effective choice because they provide adequate illumination without causing excessive glare that can impair visibility. High beam lights can reflect off the water droplets and create a blinding effect, making it more difficult to see. Parking lights do not provide enough illumination for driving conditions, and although fog lights can enhance vision in foggy conditions, they are not always equipped on all vehicles and should be used in conjunction with low beams when necessary. Low beam headlights ensure that you can see the road clearly while also being considerate of any other drivers on the road.
