Driving in fog can be extremely dangerous. Driving in fog
at night is even more hazardous. If it is foggy outside
consider postponing your trip untill it clears. Many freeway
pileups occur during foggy conditions. Most are caused by
drivers driving faster than their ability to recongnize
and stop for traffic ahead.
Don't drive with high beams because
the light will reflect back and cause glare. If you must
drive in fog, then slow down and turn on your low-beam headlights.
The right edge of
most roads is marked by white line called a "fog line".
Use the fog line to guide you during foggy conditions and
avoid being distracted by oncomming headlights The centerline
doesn't show up as well in the fog and may not be clearly
defined (ie. dashed line). Be sure to use your defroster
and wipers to keep your windsheild as clear as possible
and reduce your speed to a point where you can avoid stopped
traffic ahead. If the fog greatly reduces your visibility,
pull over and wait it out. Be sure to get as far away from
traffic as you can, such as at a rest area or parking lot.
