Defensive Driving
The best advice anyone can give about driving is:
Drive defensively.
Please start
with a very important safety device in your
vehicle: Buckle up. (See “Safety Belts”
in the Index.)
Defensive driving really means “be ready for anything.”
On city streets, rural roads or freeways,
it means
“always expect the unexpected.”
Assume that pedestrians or other drivers are going
to be
careless and make mistakes. Anticipate what they might
do. Be ready for their mistakes.
Here
you’ll find information about driving on different
kinds
of roads and in varying weather conditions. We’ve
also included many other useful tips
on driving. Rear-end
collisions are about the most preventable
of
accidents. Yet they are common. Allow enough
following distance. It’s the best defensive driving
maneuver,
in both city and rural driving. You never
know when the vehicle
in front of you is going to brake
or turn suddenly.

Death and injury associated with drinking and driving
is a national tragedy. It’s the number one contributor to
the highway death toll, claiming thousands of victims
every year.
Alcohol affects four things that anyone needs to
drive a vehicle:
Judgment
Muscular Coordination
0 Vision
0 Attentiveness.
Police records show
that almost half of all motor
vehicle-related deaths involve alcohol. In most cases,
these deaths are the result of someone who was drinking
and driving. In recent years, some
18,000 annual motor
vehicle-related deaths have been associated with the use
of alcohol, with more than
300,000 people injured.
Many adults
-- by some estimates, nearly half the adult
population
-- choose never to drink alcohol, so they
never drive after drinking. For persons under
21, it’s
against the law
in every U.S. state to drink alcohol.
There are good medical, psychological and
developmental reasons for
these laws. The
obvious way to solve this highway safety problem
is for people never
to drink alcohol and then drive. But
what if people
do? How much is “too much” if the
driver plans to drive? It’s
a lot less than many might
think. Although
it depends on each person and situation,
here is some general information on the problem.
The Blood Alcohol Concentration (BAC)
of someone
who is drinking depends upon four things:
0 The amount of alcohol consumed
0 The drinker’s body weight
0 The amount of food that is consumed before and
during drinking
0 The length of time it has taken the drinker to
consume the alcohol.
According
to the American Medical Association, a
180-lb. (82 kg) person who drinks three 12-ounce
(355 ml) bottles of beer in an hour will end up with a
BAC of about
0.06 percent. The person would reach the
same BAC by drinking three 4-ounce (120 ml) glasses
of wine or three mixed drinks if each had 1-1/2 ounces
(45 ml) of a liquor like whiskey, gin or vodka.
4-2

Downloaded from www.Manualslib.com manuals search engine It’s the amount of alcohol that counts. For example, if
the same person drank three double martinis
(3 ounces
or
90 ml of liquor each) within an hour, the person’s
BAC would be close to
0.12 percent. A person who
consumes food just before or during drinking will have
a somewhat lower BAC level.
There is a gender difference, too. Women generally have
a lower relative percentage of body water than men. Since alcohol
is carried in body water, this means that a
woman generally will reach a higher BAC level than a
man of her same body weight when each has the same
number of drinks.
The law in many
U.S. states sets the legal limit at a BAC
of 0.10 percent. In a growing number of U.S. states, and
throughout Canada, the limit
is 0.08 percent. In some
other countries, it’s even lower. The BAC limit for all
commercial drivers in the United States is
0.04 percent.
The BAC will be over
0.10 percent after three to six
drinks (in one hour). Of course, as we’ve seen, it
depends on how much alcohol is in the drinks, and how
quickly the person drinks them.
But the ability to drive is affected well below a BAC
of
0.10 percent. Research shows that the driving
skills of many people are impaired at a BAC
approaching
0.05 percent, and that the effects are worse
at night. All drivers are impaired at
BAC levels above
0.05 percent. Statistics show that the chance of being
in a collision increases sharply for drivers who have a
BAC of
0.05 percent or above. A driver with a BAC level
of
0.06 percent has doubled his or her chance of having a
collision. At a BAC level
of 0.10 percent, the chance of
this driver having a collision is 12 times greater; at a level
of
0.15 percent, the chance is 25 times greater!
4-3

Downloaded from www.Manualslib.com manuals search engine The body takes about an hour to rid itself of the alcohol
in one drink.
No amount of coffee or number of cold
showers will speed that up. “I’ll be careful” isn’t the
right answer. What
if there’s an emergency, a need to
take sudden action, as
when a child darts into the street?
A person with even a moderate BAC might not be able
to react quickly enough
to avoid the collision.
There’s something else about drinking and driving that
many people don’t know. Medical research shows
that
alcohol in a person’s system can make crash injuries
worse, especially injuries
to the brain, spinal cord or
heart. This means that
when anyone who has been
drinking
-- driver or passenger -- is in a crash, that
person’s chance of being killed or permanently disabled
is higher than
if the person had not been drinking.
Drinking and then driving is very dangerous.
Your reflexes, perceptions, attentiveness and
judgment can be affected
by even a small amount
of alcohol. You can have a serious
-- or even
fatal
-- collision if you drive after drinking.
Please don’t drink and drive
or ride with a driver
who has been drinking. Ride home in
a cab; or if
you’re with
a group, designate a driver who will
not drink.

Downloaded from www.Manualslib.com manuals search engine Control of a Vehicle
You have three systems that make your vehicle go where
you want
it to go. They are the brakes, the steering and
the accelerator. All three systems have
to do their work
at the places where the tires meet the road.
Sometimes,
as when you’re driving on snow or ice, it’s
easy to
ask more of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle.
Braking
Braking action involves perwption time and
reaction time.
First, you have to decide to push on the brake pedal.
That’s
perception time. Then you have to bring up
your foot and do
it. That’s reaction time.
Average reaction time is about 3/4 of a second. But
that’s only an average.
It might be less with one
driver and
as long as two or three seconds or more
with another. Age, physical condition, alertness,
coordination and eyesight all play
a part. So do alcohol,
drugs and frustration. But even
in 3/4 of a second, a
vehicle moving at 60 mph (100 km/h) travels 66 feet
(20 m). That could be a lot of distance in an emergency,
so keeping enough space between your vehicle and
others is important.
And, of course, actual stopping distances vary greatly
with the surface of
the road (whether it’s pavement or
gravel); the condition of the road (wet, dry, icy); tire
tread; and the condition
of your brakes.
4-5

Downloaded from www.Manualslib.com manuals search engine Avoid needless heavy braking. Some people drive in
spurts -- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This
is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes
will wear out much
faster if
you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking. That
means better braking and longer brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump
your brakes. If you do, the
pedal may get harder to push down.
If your engine
stops,
you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brakes
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent
a braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself.
You may
hear a momentary motor or clicking noise while this test
is going on. This is normal.
If there’s
a problem. with
the anti-lock brake system,
this warning light will stay
on. See “Anti-Lock Brake
ANTI -
LOCK
4-6

Downloaded from www.Manualslib.com manuals search engine The anti-lock system can change the brake pressure
faster than any driver could. The computer
is
programmed to make the most of available tire and
road conditions.
Here’s how anti-lock works. Let‘s say the road
is wet.
You’re driving safely. Suddenly
an animal -jumps out in
front of you.
You slam on the brakes. Here’s what happens with ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer
will
separately work the brakes at each front wheel and at the
rear wheels.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
4-7

Downloaded from www.Manualslib.com manuals search engine Remember: Anti-lock doesn’t change the time you need
to get your foot up to the brake pedal or always decrease
stopping distance.
If you get too close to the vehicle in
front of you, you won’t have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal
down and let anti-lock work for you. You may feel the
brakes vibrate, or you may notice some noise, but this
is normal.
Braking in Emergencies
Use your anti-lock braking system when you need to.
With anti-lock,
you can steer and brake at the same
time. In many emergencies, steering can help
you more
than even the very best braking.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system
is not functioning, you can steer but
it will take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s why:
Experienced driver or beginner, each
of us is subject to
the same laws of physics when driving on curves. The
traction of the tires against the road surface makes
it
possible for the vehicle to change its path when you turn
the front wheels.
If there’s no traction, inertia will keep
the vehicle going in the same direction.
If you’ve ever
tried to steer a vehicle
on wet ice, you’ll understand this.
