On
a
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 Suggestions
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,
making the pupils of your eyes contract repeatedly. You might even want
to
keep a cloth and some glass cleaner
in your vehicle if you need to clean
your glass frequently.
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.
