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.
Driving in the Rain
I
Rain and wet roads can mean driving trouble. On a wet road you can't stop,
accelerate or turn as well because your tire-to-road traction isn't as good as
on dry roads. And, if your tires don't have much tread left, you'll get even
less traction. It's always wise to go slower and be cautious if rain starts to
fall while you are driving. The surface may get wet suddenly when your
reflexes are tuned for driving on dry pavement.
The heavier the rain, the harder it is to see. Even if your windshield wiper
blades are in good shape, a heavy rain can make it harder to see road signs
and traffic signals, pavement markings, the edge of the road, and even
people walking.
