Your
Driving
and
the
Road
What you
do
in thedaytimecanalsoaffectyournightvision.Forexample,
if
you spend
the day
in bright sunshine you are wise
to
wear sunglasses. Your
eyes will have
less
trouble adjusting
to night.
But
if
you’redriving,don’twearsunglassesatnight.Theymaycutdownon
glarefromheadlights,buttheyalsomakealot
of thingsinvisiblethatshould
remain visible-such as parked cars, obstacles, pedestrians, or even
trains
blockingrailwaycrossings.
You may want
to
putonyoursunglassesafteryou
have pulled
into a brightly-lighted service
or refreshment area. Eyes shielded
from
that glare may adjust more quickly
to
darkness back on
the road. But
be sure
to
remove your sunglasses before you
leave
the service area.
You
can be
temporarily blinded by approaching
lights.
It
can
take a second or
two, or even several seconds,
for your eyes
to readjust
to
the dark. When
youarefacedwithsevereglare(asfromadriverwhodoesn’tlowerthehigh
beams, or a vehicle with misaimed headlights), slow down a
little. Avoid
staring directly
into
the approaching
lights.
If
there
is a
line
of opposing
traffic, make occasional glances over
the
line
of headlights
to
make certain
thatone
of
the vehicles
isn’t starting
to
move
into your
lane. Once you are
past
the bright
lights, give your eyes
time
to
readjust before resuming speed.
High
Beams
If
the vehicle approaching you has
its high beams on, signal by
flicking yours
to
high and
then back
to
low
beam. This
is
the usual signal
to
lower
the
headlightbeams. If theotherdriverstilldoesn’tlowerthebeams,resistthe
temptation
to
putyourhighbeamson.Thisonlymakestwohalf-blinded
drivers.
Ona
freeway, use your high beams only
in remote areas where you won’t
impair approaching drivers.
In some places,
like cities, using high beams
is
illegal.
When you
follow another vehicle on a
freeway or highway, use
low beams.
True, most vehicles now have day-night mirrors
that enable
the driver
to
reduce glare. But outside mirrors are not
of
this
type and high beams
from
behind can bother the driver ahead.
A
Few
More
Night
Driving
Suggesiions
Keep your windshield and all
the glass
on
your vehicle clean-inside and out.
Glare at night
is made much worse by dirt
on
the glass. Even
the
inside of
the glass can build
up
a
film caused by dust. Tobacco smoke also makes
inside
glass
surfaces very
filmy and can
be
a
vision hazard
if
it’s
left
there.
Dirty glass makes
lights dazzle and
flash more
than clean glass would,
makingthepupils
of
your eyes contract repeatedly. You might even want
