How to Follow Other Vehicles When Driving in Foggy Weather?

There are three key precautions for driving in foggy conditions: 1. Use low beams: Many drivers instinctively assume high beams provide better visibility over longer distances. However, the opposite is true in fog - low beams should be used. High beams project light upward, causing light diffusion through fog particles that creates a blinding white wall ahead. 2. Activate headlights and fog lights: When visibility drops below 1km, turn on all vehicle lights (except high beams) including parking lights, width indicators, and hazard lights to alert surrounding vehicles. 3. Frequent horn usage: Drivers should use the horn more frequently in fog to enhance safety awareness.
When driving in foggy conditions, I like to imagine myself as slow as a snail. It's essential to reduce speed, generally not exceeding 50 kilometers per hour, because heavy fog makes it hard to see ahead, leaving little time to react in emergencies. Increase your following distance—if you normally leave 50 meters in clear weather, make it at least 150 meters in foggy conditions, so you can stop safely if the car ahead brakes suddenly. Don't forget to turn on your front and rear fog lights—they help you see the road better and make your car more visible to others, but avoid using high beams, as the light reflects and worsens visibility. Crack the window slightly to listen for surrounding sounds, which can help you gauge your position. In bad weather, stay calm—don't rush, arriving safely is what matters most. Keep some anti-fog spray handy and apply it to the windshield in advance to minimize condensation.
