What Causes Fog ?
Fog is defined as a thick cloud of water droplets, 0.00039 to 0.00156 inches in diameter, suspended in the atmosphere at or near the earth’s surface and reducing visibility to below half a mile.
Off all the recommendations below, driving with low beam is the most recommended one, never drive with high beam. Your high beam headlights produce a wall of glare — a whiteout — from the light bouncing off these droplets of water. You’re being blinded by the glare of your own lights reflected off the water vapor in front of you. Similar experiences occur in rain, snow, dust, etc.
- DRIVE WITH LIGHTS on low beam. High beams will only be reflected back off the fog and actually impair visibility even more. Your lights help other drivers see your vehicle, so be sure they all work. Keep your windshield and headlights clean, to reduce the glare and increase visibility.
- SLOW DOWN – and watch your speedometer – before you enter a patch of fog. Be sure that you can stop within the distance that you can see. Fog creates a visual illusion of slow motion when you may actually be speeding. Speed is a major factor in fog-related crashes.
- WATCH OUT for slow-moving and parked vehicles. Listen for traffic you cannot see. Open your window a little, to hear better.
- REDUCE THE DISTRACTIONS in your vehicle. Turn off the radio and cell phone. Your full attention is required
- USE WIPERS AND DEFROSTERS liberally for maximum visibility. Sometimes it is difficult to determine if poor visibility is due to fog or moisture on the windshield.
- BE PATIENT. Avoid passing and/or changing lanes.
- SIGNAL TURNS well in advance and brake early as you approach a stop.
- DO NOT STOP on a freeway or heavily travelled road. You could become the first link in a chain-reaction collision. If you must pull off the road, signal (people tend to follow tail lights when driving in fog), then carefully pull off as far as possible. After pulling off the road, turn on your hazard flashers(hazard lights should only be used when you pull over to show that you are parked on the side of the road). Move away from the vehicle. Source
