What should a driver do when driving in fog regarding headlights?

When driving in fog, utilizing low-beam headlights is essential because they are designed to reduce glare that can occur when lights are shone directly into fog, rain, or snow. High-beam headlights can reflect off the moisture in the air, creating a blinding effect that makes it even more difficult to see. Low beams, on the other hand, provide adequate illumination of the roadway without causing excessive glare that can impair the vision of both the driver and other road users.

Turning off the headlights is not advisable, as it severely reduces visibility, making it hard to see the road and be seen by others. Relying solely on daytime running lights may also not provide sufficient illumination in foggy conditions, as these lights are typically less bright than standard low beams and are not designed for nighttime driving or fog situations.

In foggy conditions, ensuring that your low-beam headlights are activated is key to enhancing safety for everyone on the road.
