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.
Driving in the Rain
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

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.
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.
Some Other Rainy Weather Tips
Turn on ybur low-beam headlights - not just your parKing lights - to
help make
you more visible to others.
Besides slowing down, allow some extra following distance. And be
especially careful when you pass another vehicle. Allow yourself more
clear room ahead, and be prepared to have your view restricted by road
spray.
Have good tires with proper tread depth. (See “Tires” in the Index.)
City Driving
One of the biggest problems with city streets is the amount of traffic on
them. You’ll want to watch out for what the other drivers are doing and pay
attention to traffic signals.
Here are ways
to increase your safety in city driving:

Run your engine only as long as you must. This saves fuel. When you run
the engine, make it
go a little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the heat that you get and it keeps
the battery (or batteries) charged.
You will need a well-charged battery (or
batteries) to restart the vehicle, and possibly for signaling later on with your
headlights. Let the heater run for awhile.
If you have a diesel engine, you may have to run it at a higher speed to get
enough heat. Then, shut the engine
off and close the window almost all the
way to preserve the heat. Start the engine again and repeat this only when
you feel really uncomfortable from the cold. But do it as little as possible.
Preserve the fuel as long as you can.
To help keep warm, you can get out of
the vehicle
and do some fairly vigorous exercises every half hour or so until
help comes.
Power Winches
If you wish to use a power winch on your vehicle, only use it when your
vehicle is stationary or anchored.
NOTICE:
When operating a power winch on your vehicle, always leave the
transmission in “N” (Neutral). Leaving a automatic
transmission in “P”(Park) while using a power winch may \
damage the transmission. Also, leaving a automatic or manual
transmission in gear while using an power winch may damage
the transmission.
Use the regular brakes, set the parking brake, or block the wheels to keep
your vehicle from rolling.
