According to the National Weather Service (NWS):
- Fog contributes to travel accidents
- Water particles remain suspended near surfaces rather than falling like drizzle, creating hazards for drivers
Fog and Visibility
- Fog is more common in basins, deep valleys, and near bodies of water
- Light fog can quickly become dense
- In foggy conditions, low-beam headlights (not high-beam headlights) provide better visibility
Driving in Fog
- Slow down; allow extra time to reach your destination
- Use low beams and fog lights, if applicable
- Never use high-beams, which cause glare
- Engage 4-way flashers when visibility is near-zero
- Increase following distance to account for sudden stops
- Stay in the proper lane by following the lines on the road
