Drive with lights on LOW beam. High beams will reflect off the fog, creating a "white wall" effect.

Reduce your speed - and watch your speedometer. Fog creates a visual illusion of slow motion when you may actually be speeding.

Avoid crossing traffic lanes.

Travel with the driver’s window partially open. Listen for traffic.

Watch for CHP pace cars to guide you.

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 lifts.
