Dense fog can create dangerous conditions on the road. The safest thing to do is pull over into a parking area until the fog clears. If you must continue your trip, keep in mind these tips for driving in fog:
Minimize distractions. Turn off your cell phone and the stereo.
Reduce your speed. Because you can't see the road or other vehicles, a low speed can help you react safely.
Roll down your window to listen for cars.
Use roadside reflectors as a guide. The markings can help you navigate twists and turns.
Turn off cruise control for more control of your vehicle.
Use windshield wipers and defrosters to limit excess moisture on the window.
Drive with low beams and fog lights. High beams can worsen visibility because they reflect off the fog.
If you can pull over to a safe area, make sure to do the following:
Use your turn signal. Other drivers may be using your taillights as a guide, so alert them that you're pulling off the road.
Pull off away from the road. If drivers can't see the shoulder, they likely won’t see your vehicle either.
Turn on your hazard lights to help other drivers know you're stopped. Avoid using flashing lights while driving.
