Driving in the Fog is scary for all of us. It requires your full concentration. During weather situations like heavy fog, your visibility is poor and can negatively impact your driving and personal safety.
Always:
Slow down when approaching fog and maintain a slow speed
Turn on low beams, fog lights, and warning signals
Use your windshield wipers and defroster to increase visibility
Roll down windows to hear other vehicles nearby
Keep a good distance from the vehicle ahead of you
Use your signal earlier if you plan to turn
Break early and gently so vehicles behind you have a chance to react to your driving
If really nervous, never hesitate pulling off the road as far to the right that you safely can. Do not proceed until visibility improves. Better Safe than Sorry.
