Tips from the National Weather Service for driving in fog

  • Drive with lights on low beam.
  • Reduce speed. Allow for plenty of room between you and other cars.
  • Avoid crossing traffic unless absolutely necessary.
  • Listen for traffic you cannot see.
  • Use wipers and defroster as necessary for maximum vision.
  • Be patient! Don’t pass lines of traffic.
  • Unless absolutely necessary, don’t stop on any freeway or other heavily traveled road.
  • If your car is disabled or you can’t continue, pull well onto the shoulder and turn off lights. Move away from your vehicle.
  • Consider postponing your trip until the fog clears.
  • Be especially cautious in and near school zones. Watch for flashing yellow or red signals on school buses. Watch for children waiting for buses in the fog.
  • Also, be aware that smoke from grass and forest fires along roadways can combine with fog to rapidly drop visiblities to zero.
