What should you do when driving in fog?

When driving in fog, using low-beam headlights is crucial because they are designed to illuminate the road immediately in front of your vehicle while reducing the amount of light that reflects off the fog and back towards your eyes. High-beam headlights can create a wall of light that reflects off the water droplets in the fog, causing visibility to decrease and potentially blinding the driver. Additionally, driving at a higher speed in foggy conditions can be dangerous due to significantly reduced visibility and the increased risk of accidents. Keeping headlights off would make it extremely difficult to see the road and any potential hazards, resulting in a dangerous situation. Therefore, utilizing low-beam headlights is the safest and most effective option for maintaining visibility while navigating through foggy conditions.
