Fog is a collection of water droplets that are suspended in the air just above Earth's surface. Radiation fog forms overnight when the air near the ground cools and stabilizes.  Fog forms when the cooling causes the air to reach saturation.  Radiation fog is most common during the autumn and winter.  Fog can be hazardous to drivers, boaters and aviators, especially when visibility drops to 1/4 mile or less.

HOW TO PREPARE FOR FOG
 

• Pay attention to your local weather forecast.

• Allow extra time to reach your destination.

• Consider installing fog lights on your vehicle.

​

WHAT TO DO IF DRIVING IN FOG
 

• Slow down.

• Never use your high beams in fog.  Use your low

beams and fog lights, if available.

• Allow plenty of distance between your vehicle

and the vehicle in front of you in case of

sudden stops.

• If driving in dense fog when the visibility is close to zero, turn on your hazard lights so other drivers can see your vehicle.

• If you feel unsafe driving, safely pull off the road (as far as possible) and keep your hazard lights on.
