We’re all familiar with traffic lights or stop lights. Often green arrows are -
being used in the lights for improved traffic control. On some multilane
roads, green arrows light up, indicating that traffic in one or more lanes
can move or make
a turn. Green arrows don’t mean “go no matter what.’’
You’ll still need to proceed with caution, yielding the right
of way to
pedestrians and sometimes to other vehicles.
Some traffic lights also use red arrows to
signify that you must stop before
turning
on red.

ROADWAY
Many city roads and expressways, and even bridges, use reversible-lane
traffic control during rush hours.
A red X light above a lane means no
driving in that lane at that time.
A green arrow means you may drive in
that lane.
Look for the signs posted to warn drivers what hours and days
these systems are
in effect.
PAVEMENT MWNGS
Pavement markings add to traffic signs and signals. They give information
to drivers without taking attention from the roadway.
A solid yellow line
on your side of the road
or lane means “don’t cross.”

Turn and lane change signals. Always signal when you plan to turn or
change lanes.
If necessary, you can use hand signals out the window: Left arm straight

for a left turn, down for slow or about-to-stop, and up for a right turn.
Slowing down. If time allows, tap the brake pedal once or twice
in
advance of slowing or stopping. This warns the driver behind you.
Disabled. Your four-way flashers signal that your vehicle
is disabled or is
a hazard. See “Hazard Warning Flashers” in the Index.

The traffic police officer is also a source of important information. The
officer’s signals govern, no matter what the traffic lights or other signs
say.

encounter.
DEFENSIKE DmNG
The best advice anyone can give about driving is: Drive defensively.
Please start with a very important safety device in your Cadillac: 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.
Expect children to dash out from behind parked cars, often followed
by
other children. Expect occupants in parked cars to open doors into traffic.
Watch for movement in parked cars
-- someone may be about to open a
door.

Be ready to brake if necessary as you go through intersections.
You may
not have to use the brake, but
if you do, you will be ready.
If you’re driving through a shopping center parking lot where there are
well-marked lanes, directional arrows, and designated parking areas,
expect some drivers to ignore all these markings and dash straight toward
one part
of the lot.
Pedestrians can be careless. Watch
for them. In general, you must give
way to pedestrians even if you know you have the right of way.
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.
Here’s
a final bit of information about defensive driving. The most
dangerous time for driving in the
U.S. is very early on Sunday morning. In
fact, GM Research studies show that the most and the least dangerous
times for driving, every week, fall on the same day. That day is Sunday.
The most dangerous time is Sunday from
3 a.m. to 4 a.m. The safest time
is Sunday from
10 a.m. to 11 a.m. Driving the same distance on a Sunday
at
3 a.m. isn’t just a little more dangerous than it is at 10 a.m. It’s about
134 times more dangerous!

DRUNKEN DRMNG
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 takes away three things
that anyone needs to drive a vehicle:
Judgment
0 Muscular Coordination
Vision
Police records show that half
of all motor vehicle-related deaths involve
alcohol
- a driver, a passenger or someone else, such as a pedestrian,
had been drinking. In most cases, these deaths are the result
of someone
176
Page 190 of 406

Downloaded from www.Manualslib.com manuals search engine who was drinking and driving. Over 25,000 motor vehicle-related deaths
occur each year because
of alcohol, and thousands of people are injured.
Just how much alcohol is too much if a person plans to drive? Ideally, no
one should drink alcohol and then drive. But
if one does, then what’s “too
much”? It can be 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 Content
(BAC) of someone who is drinking depends
upon four things:
How much alcohol is in the drink.
0 The drinker’s body weight.
a 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.
I
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 ml) glasses of wine or three
177
Page 191 of 406

Downloaded from www.Manualslib.com manuals search engine 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 slightly lower
BAC
level.

The law in most US. states sets the legal limit at a BAC of 0.10 percent.
In Canada the limit
is 0.08 percent, and in some other countries it’s lower
than that. 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 it’s
very important to keep in mind that 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 an accident
increases sharply
for drivers who have a BAC of 0.05 percent or above. A
driver with a BAC level of
0.06 percent (three beers in one hour for a
180-pound or 82 kg person) has doubled his or her chance of having an

an accident is
six times greater; at a level of 0.15 percent, the chances are
twenty-five times greater! And, 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
person with a higher 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. That’s especially true for brain, spinal cord
-- and heart injuries. That means that if anyone who has been drinking --
driver or passenger -- is in a crash, the chance of being killed or
permanently disabled is higher than if that person had not been drinking.
And we’ve already seen that the chance
of a crash itself is higher for
drinking drivers. -
* Drinking and then driving is very dangerous. Your reflexes,
perceptions, and judgment will be affected by even a small
amount of alcohol. You could have a serious -- or even fatal --
accident 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 pup, designate a driver who will not drink
- CONTROL OF A WHICLE
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. --
