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 or turn suddenly.
Defensive Driving
The best advice anyone can give about driving is:
Drive defensively.

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
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 17,000 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:
The amount of alcohol consumed
0 The drinker’s body weight
0 The amount of food that is consumed before and
during drinking
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
(I 20 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.

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!

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.

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.
Braking
Braking action involves perception 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 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; the condition of your brakes; the weight
of the
vehicle and the amount
of brake force applied.
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.
