1 Section 4 Your Driving and the Road
I I
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.
Defensive Driving
The best advice anyone can give about driving is: Drive
defensively.
Please start
with a very important safety device in your
Oldsmobile: 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.
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
01- turn suddenly.

Drunken Driving
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
0 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, 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 2 1, 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:
How much alcohol consumed
The drinker’s body weight
The amount of food that is consumed before and
during drinking
0 The length of time it’s taken the drinker to consume
the alcohol
According
to the American Medical Association, a
180-pound (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 nll) 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

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

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 carefbl” 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.

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 perception tir7z.e and rzaction 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 34 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 kmh)
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.
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,
4-5

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 (ABS)
Your Oldsrnobile has an advanced electronic braking
system that
will help prevent a braking skid.

ANTI-
CHECK
OABES
This light on the
instrument panel
will
come on briefly when
you start your vehicle. When you
start yo~~r vehicle, or when
you begin to drive
away, you may hear a momentary motor or clicking
noise. And you may even notice that your brake pedal
moves a little while this is going on.
This is the ABS
system testing itself.
If there’s a problem with the
anti-lock brake system, the anti-lock brake system
warning light
will stay on or flash.
See “Anti-Lock Brake System Warning Light”
in the
Index.

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.
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.
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.
Remember: Anti-lock doesn’t change the time you need
to get your foot up to the brake pedal. 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.

To Use Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
and
let anti-lock work for you. You may feel the system
working, 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 YOLI 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.
The traction you can get
in a curve depends on the
condition of your tires and the road surface, the angle at
which the curve is banked, and your speed. While
you’re
in a curve, speed is the one factor you can
control.
Suppose you’re steering through
a sharp curve. Then
you suddenly accelerate. Both control systems
--
steering and acceleration -- have to do their work where
the tires meet the road. Adding the sudden acceleration
can demand too much of those places. You can lose
control.
What should you do
if this ever happens? Ease up on the
accelerator pedal, steer the vehicle the way you want
it
to go, and slow down.
Speed limit signs near curves warn
that you should
adjust your speed. Of course, the posted speeds are
based on
good weather and road conditions. Under less
favorable conditions you’ll want to
go slower.
