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.
Tips
on
Driving in Fog
If you get caught
in
fog, turn your
headlights on low beam, even in
daytime. You’ll see
-
and be seen
-
better.
Don’t use your high beams. The light
will bounce off the water droplets that
make up fog and reflect back at you.
Use your defogger. In high humidity,
even a light buildup of moisture on the
inside
of
the glass will cut down on your
already limited visibility. Run your
windshield wipers and washer
occasionally. Moisture can build up on
the outside glass, and what seems to be
fog may actually be moisture on the
outside
of
your windshield.
Treat dense
fog
as an emergency. Try to
find a place to pull off the road.
Of
course you want to respect another’s
property, but you might need to put
something between you and moving
vehicles
-
space, trees, telephone poles,
a private driveway, anything that
removes you from other traffic.
If visibility
is
near zero and
you
must
stop but are unsure whether you are
away from the road, turn your lights on,
start your hazard warning flashers, and
sound your horn at intervals or when
you hear approaching traffic.
Pass other vehicles
in
fog only
if
you
can see far enough ahead to pass safely.
Even then, be prepared to delay your
pass
if
you suspect the fog
is
worse up
ahead. If other vehicles try to pass you,
make
it
easy for them.
