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. SeeSafety Belts: They
Are for Everyone on page 17.
{CAUTION:
Defensive driving really means “Be ready
for anything.” On city streets, rural roads,
or expressways, 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 and be ready. Rear-end
collisions are about the most preventable
of accidents. Yet they are common. Allow
enough following distance. Defensive
driving requires that a driver concentrate
on the driving task. Anything that
distracts from the driving task makes
proper defensive driving more difficult
and can even cause a collision, with
resulting injury. Ask a passenger to help
do these things, or pull off the road in a
safe place to do them. These simple
defensive driving techniques could save
your life.

Drunken Driving
Death and injury associated with drinking and
driving is a national tragedy. It is 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
Vision
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, more
than 16,000 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 is 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 eliminate the leading highway
safety problem is for people never to drink
alcohol and then drive. But what if people do?
How much is “too much” if someone plans
to drive? It is 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:
The amount of alcohol consumed
The drinker’s body weight
The amount of food that is consumed before
and during drinking
The length of time it has taken the drinker to
consume the alcohol

ProCarManuals.com

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 liquors like
whiskey, gin, or vodka.It is 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 will when each has the same
number of drinks.
The law in most U.S. states, and throughout
Canada, sets the legal limit at 0.08 percent. In
some other countries, the limit is even lower. For
example, it is 0.05 percent in both France and
Germany. 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 have
seen, it depends on how much alcohol is in the
drinks, and how quickly the person drinks them.

ProCarManuals.com

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!
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 will be careful”
is not the right answer. What if there is 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 is something else about drinking and driving
that many people do not 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.
{CAUTION:
Drinking and then driving is very
dangerous. Your reexes, 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 do not drink and drive or ride with a
driver who has been drinking. Ride home in
a cab; or if you are with a group, designate
a driver who will not drink.

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 are driving on snow or
ice, it is easy to ask more of those control systems
than the tires and road can provide. That means
you can lose control of your vehicle. SeeTraction
Control System (TCS) on page 217and
Electronic Stability Control on page 219.
Adding non-Saturn accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 253.
Braking
SeeBrake System Warning Light on page 168.
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake
pedal. That is perception time. Then you have to
bring up your foot and do it. That is reaction time.
Average reaction time is about three-fourths of a
second. But that is 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
three-fourths 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 is
pavement or gravel; the condition of the road,
whether it is wet, dry, or icy; tire tread; the
condition of the brakes; the weight of the vehicle;
and the amount of brake force applied.

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. The brakes may not have
time to cool between hard stops. The 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 vehicle’s engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to
push down. If the 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.
Adding non-Saturn accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 253.Antilock Brake System (ABS)
Your vehicle has the Antilock Brake System (ABS),
an advanced electronic braking system that will
help prevent a braking skid.
When you start the engine and begin to drive
away, ABS will check itself. You might hear
a momentary motor or clicking noise while this test
is going on, and you might even notice that the
brake pedal moves a little. This is normal.
If there is a problem
with ABS, this warning
light will stay on.
SeeAntilock Brake
System Warning Light
on page 169.

Let us say the road is wet and you are driving
safely. Suddenly, an animal jumps out in front of
you. You slam on the brakes and continue braking.
Here is 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
wheel.ABS can change the brake pressure faster than
any driver could. The computer is programmed to
make the most of available tire and road
conditions. This can help you steer around the
obstacle while braking hard.
As you brake, the computer keeps receiving
updates on wheel speed and controls braking
pressure accordingly.
