Your Driving and the Road
124
Driving at Night
Night driving is more dangerous than
day driving. One reason is that some
drivers are likely to be impaired
- by
alcohol or drugs, with night vision
problems, or by fatigue.
Here are some tips on night driving.
Drive defensively.
Don’t drink and drive.
Adjust your inside rearview mirror to
reduce the glare from headlights
behind you.
Since you can’t see as well, you may
need to slow down and keep more
space between you and other vehicles.
Slow down, especially on higher
speed roads. Your headlights can light
up only
so much road ahead.
In remote areas, watch for animals.
If you’re tired, pull off the road in a
safe place and rest.
Night Vision
No one can see as well at night as in the
daytime. But as we get older these
differences increase. A 50-year-old
driver may require at least twice as
much light to see the same thing at
night as
a 20-year-old.
What you do in the daytime can also
affect your night vision. For example, 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’re driving, don’t wear
sunglasses at night. They may cut down
on glare from headlights, but they also
make a lot of things invisible.
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
you are faced with severe glare (as from
a driver who doesn’t lower the high
beams, or a vehicle with misaimed
headlights), slow down a little. Avoid
staring directly into the approaching
lights.
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.
Dirty glass makes lights dazzle and
flash more than clean glass would,
malting the pupils of your eyes contract
repeatedly.
Remember that your headlights light up
far less of a roadway when
you are in a
turn or curve. Keep your eyes moving;
that way, it’s easier to pick out dimly
lighted objects. Just as your headlights
should be checked regularly for proper
aim,
so should your eyes be examined
regularly. Some drivers suffer from
night blindness
- the inability to see in
dim light
- and aren’t even aware of it.
