CAUTION
I
Wet brakes can cause
accidents. They won't work
d l 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 vehicle wash,
apply your brake pedal lightly until
your brakes work normally.
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're going fast enough. When
your vehicle is hydroplaning, it has little
or no contact with the road.
You might not be aware of hydroplaning.
You could drive along for some time
without realizing your tires aren't in
constant contact with the road. You
could find out the hard way: when you
have to slow, turn, move out to pass-or
if you get hit by a gust of wind. You could
suddenly find yourself out of control.
Hydroplaning doesn't happen often. But
it can if your tires haven't 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 isn't a hard and fast
rule about hydroplaning. The best
advice is to slow down when it is
raining, and be careful.
