What should you NOT do when driving in fog?

Using high-beam headlights in fog is not advisable because the light can reflect off the fog droplets, creating a glare that actually reduces visibility. This reflection can cause a blinding effect, making it difficult for the driver to see ahead. Instead, low-beam headlights are recommended in foggy conditions as they provide better visibility without the excessive glare. This understanding of how light interacts with fog is crucial for maintaining safety while driving in such conditions.

Maintaining safe driving practices such as using turn signals, slowing down, and keeping a safe following distance are all vital for ensuring safety during reduced visibility scenarios like fog.
