What should you do if driving in fog to improve visibility?

When driving in fog, using low beams and watching for road markings is the best course of action to improve visibility. Low beams are specifically designed for use in conditions of reduced visibility, such as fog, rain, or snow. They produce a light that is angled downward, which reduces glare and helps illuminate the road directly in front of the vehicle. This is crucial because fog reflects light, and high beams can create a blinding effect, making visibility even worse.

In addition to using the appropriate headlights, monitoring road markings is important for maintaining your position on the roadway and navigating through the fog safely. This combined strategy allows for better judgments regarding speed and safe maneuvering.

While pulling over until visibility improves can be a safe option in extremely dense fog, it is not always practical. Staying vigilant on the road while using low beams and focusing on road markings generally allows for safer travel. Other suggested actions, such as increasing speed or using high beams, would hinder rather than help visibility and create greater risks.
