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, making 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.
