How to Stay Safe During Dense Fog Conditions

When a Dense Fog Advisory is in effect, it's crucial to exercise caution:

• Drive Slowly: Reduce your speed to ensure you can stop within the distance you can see.

• Use Low-Beam Headlights: High beams can reflect off the fog, reducing visibility.

• Increase Following Distance: Maintain a safe distance from the vehicle ahead to allow ample stopping time.

• Avoid Sudden Lane Changes: Only change lanes when necessary and ensure the path is clear.

• Use Fog Lights if Available: If your vehicle is equipped with fog lights, turn them on to improve visibility.

• Stay Alert for Sudden Changes: Fog can be patchy; remain vigilant for unexpected reductions in visibility. (weather.gov)
