DRIVING YOUR VEHICLE
78J00-03E
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 the headlamps light up far
less of a roadway when you are in a turn or
curve. Keep your eyes moving; that way, it
is easier to pick out dimly lighted objects.
Just as the headlamps 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 are not even aware
of it.
Driving in Rain and on Wet Roads
1527470
Rain and wet roads can mean driving trou-
ble. On a wet road, you cannot stop, accel-
erate, or turn as well because your tire-to-
road traction is not as good as on dry
roads. And, if your tires do not have much
tread left, you will get even less traction. It
is always wise to go slower and be cau-
tious if rain starts to fall while you are driv-
ing. 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.
It is wise to keep your windshield wiper and
washer system in good shape and keep
your windshield washer fluid reservoir filled
with washer fluid. Replace your windshield
wiper inserts when they show signs of
streaking or missing areas on the wind-
shield, or when strips of rubber start to
separate from the inserts.
Driving too fast through large water pud-
dles or even going through some car
washes can cause problems, too. The
water may affect your brakes. Try to avoid
puddles. But if you cannot, try to slow
down before you hit them.
Hydroplaning
Hydroplaning is dangerous. So much
water can build up under your tires that
they can actually ride on the water. This
can happen if the road is wet enough and
you are going fast enough. When your
vehicle is hydroplaning, it has little or no
contact with the road.
Hydroplaning does not happen often. But it
can if your tires do not have much tread or
if the pressure in one or more is low. It can
happen if a lot of water is standing on the
road. If you can see reflections from trees,
telephone poles, or other vehicles, and
raindrops dimple the water’s surface, there
could be hydroplaning.
Hydroplaning usually happens at higher
speeds. There just is not a hard and fast
rule about hydroplaning. The best advice is
to slow down when it is raining.
WARNING
Wet brakes can cause accidents.
They may not work as well in a quick
stop and may cause pulling to one
side. You could lose control of the
vehicle. After driving through a large
puddle of water or a car wash, apply
the brake pedal lightly until the
brakes work normally.
