What type of headlights should be used when driving in fog?

When driving in fog, using low beam headlights is essential for safety and visibility. Low beam headlights provide a wider and shorter beam of light that is less likely to reflect off the fog, rain, or snow back into the driver's eyes, which can happen when high beams are used. This reflection creates a glare, making it more difficult to see the road ahead clearly and increasing the risk of accidents.

Low beam headlights are designed to illuminate the road directly in front of the vehicle while minimizing light that goes upward and creates glare. This visibility is crucial in foggy conditions, where the atmosphere reduces overall sight distance. Therefore, using low beams allows drivers to see the road and any obstacles while not dazzling themselves or other drivers.

Fog lights, which are another option for driving in fog, are designed specifically for such conditions; however, using them in combination with low beams can enhance safety without causing glare. Parking lights are not adequate for driving since they do not provide sufficient illumination.
