What to Do When Encountering Heavy Fog or Extremely Low Visibility?

When encountering heavy fog or extremely low visibility, the solution is to turn on the hazard warning lights and fog lights, and choose a safe location to park. The maintenance methods for car lights are: 1. Check the sealing of the headlights, as moisture inside the headlights will reduce the lifespan of the bulbs; 2. If the sealing ring between the lens and reflector is damaged, replace it promptly; 3. Clean the bulbs—use alcohol-soaked cotton swabs to remove dust and dirt, then let them dry without touching the bulbs with hands or cloth; 4. Clean the reflector—use clean cotton dipped in hot water to gently clean without rubbing, to avoid damaging the reflector coating.
When it comes to driving in thick fog, I believe slowing down is crucial. I remember one winter with heavy fog when I reduced my speed to below 40 km/h and turned on both front and rear fog lights, as using high beams would cause light reflection and make visibility even worse. Maintaining a safe distance is also vital—doubling the usual gap gives extra buffer time in case the car ahead brakes suddenly. Never rush to overtake or change lanes; most fog-related accidents are chain-reaction rear-end collisions caused by obstructed vision. If the fog is extremely dense with visibility under 10 meters, I’ll find a safe spot like a service area or roadside parking zone, turn on hazard warning lights, and wait for the fog to lift. I also keep a defogging spray in my car—a quick spray clears up the windshield significantly. These habits have greatly improved my driving safety, and I’ve never had any mishaps.
