The below is from Weather.com and I thought it appropriate for this mornings commute.

Fog can be thought of as a cloud at ground level. It forms when the temperature drops to the dew point (the temperature at which air is saturated),
and invisible water vapor in the air condenses to form suspended water droplets.
Fog can reduce visibility to 1/4 mile or less, creating hazardous driving
conditions. If you can't postpone your trip until dense fog lifts -- usually by
late morning or the afternoon -- follow these tips:
* Drive with lights on low beam. High beams will only be reflected back off
the fog and actually impair visibility even more.
* Reduce your speed -- and watch your speedometer. Fog creates a visual
illusion of slow motion when you may actually be speeding.
* Listen for traffic you cannot see. Open your window a little, to hear
* Use wipers and defrosters as necessary for maximum visibility.
* Use the right edge of the road or painted road markings as a guide.
* Be patient. Do not pass lines of traffic.
* Do not stop on a freeway or heavily traveled road. If your car stalls or
becomes disabled, turn your vehicle's lights off, and take your foot off of the
brake pedal. People tend to follow tail lights when driving in fog. Move away
from the vehicle to avoid injury.
