Here are some tips on night driving.
D
Drive defensively.
D
Don't drink and drive.
D
Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.
D
Since you can't see as well, you may need to slow
down and keep more space between you and
other vehicles.
D
Slow down, especially on higher speed roads. Your
headlamps can light up only so much road ahead.
D
In remote areas, watch for animals.
D
If you're tired, pull off the road in a safe place
and rest.
No one can see as well at night as in the daytime. But as
we get older these differences increase. A 50
driver may require at least twice as much light to see the
same thing at night as a 20

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
headlamps, but they also make a lot of things invisible.
You can be temporarily blinded by approaching
headlamps. 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
headlamps), slow down a little. Avoid staring directly
into the approaching headlamps.
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 headlamps 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 headlamps should be checked
regularly for proper aim, so should your eyes be examined
regularly. Some drivers suffer from night blindness
