Your
Driving
and
the
Road
~
~
Driving
in
Fog,
Mist
and
Haze
1
AN459006
Fogcanoccurwithhighhumidityorheavyfrost.Itcanbe
so
mildthatyou
can see through
it for several hundred feet (meters). Or
it
might be
so
thick
thatyoucanseeonlyafewfeet(meters)ahead.Itmaycomesuddenly
to
an otherwise clear road. And
it can be a major hazard.
When you drive
into a
fog patch, your visibility will be reduced quickly. The
biggest dangers are striking the vehicle ahead or being struck by the one
behind. Try
to
“read” the fog density
down
the road.
If
the vehicle ahead
starts to become
less clear
or,
at night,
if
the taillights are harder to see, the
fog is probablythickening.Slowdowntogivetrafficbehindyouachance
to
slow down. Everybody then has a better chance
to
avoid hitting the vehicle
ahead.
A
patch
of
dense fog may extend only
for a fewfeet(meters)orformiles
(kilometers); you can’t really
tell whileyou’re in
it.
You canonlytreatthe
situation with extreme care.
One common
fog condition-sometimes
called mist or ground
fog-can
happen in weather
that seems perfect, especially at night or
in the early
morning in valley and
low, marshy areas. You
can
be suddenly enveloped
in
thick, wet haze
that may even coat your windshield. You can often spot
these
fog patches
or
mist
layers with your headlights. But sometimes they can be
waiting for you
as you come over a hill
or
dip
into a shallow
valley.
Start
your
windshield wipers and washer to help clear accumulated road dirt. Slow
down carefully.
