Use low-beam headlights and fog lights for best visibility. Turn on your lights even in the daytime fog and be alert for other drivers who may have forgotten to turn on their lights. It is important to be seen.
Turn on your four-way flashers. This will give vehicles approaching you from behind a quicker opportunity to see and notice your vehicle.
Watch out for vehicles on the side of the roadway. Seeing taillights or headlights in front of you may not be a true indication of where the road is ahead of you. The vehicle’s driver may be disoriented by the fog, and the vehicle may not be on the road at all.
Use roadside highway reflectors as guides to determine how the road may curve ahead of you.
Use wipers and defroster as necessary to maximize visibility.
Listen for traffic you cannot see.
Don’t drive faster than your vision, reaction time and stopping distance permit.
