Cars driving on road in fog
 
  • Drive slowly, use fog lights if you have them, turn on wipers and the defroster to help keep the windshield clear, and carefully look for other cars.
  • Use low-beam headlights. High beams can decrease visibility by creating glare that reflects back at you.
  • Turn on the hazard flashers.
  • Turn off the radio and open the windows to listen for traffic.
  • Try to follow the road's edge or center line to ensure that you don't stray from your lane.
  • Don't stop in the road. If you must stop, pull off to the side.
