When driving in heavy fog at night, what type of headlights should be used?

Using low beam headlights when driving in heavy fog at night is crucial for maintaining visibility and safety. Low beam headlights emit a light that is directed towards the road, which reduces the amount of light that reflects off the fog and back into the driver's eyes. This minimizes glare and helps the driver see the road conditions clearly.

In contrast, high beam headlights can be blinding in foggy conditions, as they illuminate the fog droplets and create a wall of light, making it more difficult to see ahead. Parking lights are not sufficient for driving as they do not provide adequate illumination for the road. Additionally, driving without lights is unsafe and illegal, especially in reduced visibility conditions like fog. Therefore, utilizing low beam headlights is the most effective way to navigate through heavy fog at night.
