What should you do when driving in foggy conditions?

When driving in foggy conditions, using low beams is the best practice because it minimizes the amount of light that is reflected back at you, improving visibility. High beams can actually worsen visibility in fog, rain, or snow since the light can reflect off the particles in the air, creating a glare that can obscure your view.

In fog, it's crucial to rely on low beams because they project light closer to the ground where it is needed most, allowing you to see both the road and objects nearby more clearly. Maintaining a constant speed is risky in fog as it can lead to potential hazards due to reduced visibility. Additionally, driving without headlights is not only unsafe but against traffic laws, as it completely obstructs your ability to see and be seen. Therefore, using low beams is the most effective choice to ensure safe driving in foggy conditions.
