The driver of a vehicle about to pass another on a
two-lane highway waits for just the right moment,
accelerates, moves around the vehicle ahead, then goes
back into the right lane again. A simple maneuver?
Not necessarily! Passing another vehicle on a two-lane highway is a potentially dangerous move, since the
passing vehicle occupies the same lane as oncoming
traffic for several seconds. A miscalculation, an error in
judgment, or a brief surrender to frustration or anger can
suddenly put the passing driver face to face with the
worst of all traffic accidents
-- the head-on collision.
So here are some tips for passing:
0 “Drive ahead.” Look down the road, to the sides and to
crossroads for situations that might affect your passing
patterns.
If you have any doubt whatsoever about
making a successful pass, wait for a better time.
Watch for traffic signs, pavement markings and lines.
If you can see a sign up ahead that might indicate a
turn or an intersection, delay your pass. A broken
center line usually indicates it’s
all right to pass
(providing the road ahead is clear). Never cross a solid
line on your side of the lane or a double solid line,
even if the road seems empty of approaching traffic.
0 Do not get too close to the vehicle you want to
pass while you’re awaiting an opportunity. For one
thing, following too closely reduces your area of
vision, especially if you’re following a larger
vehicle. Also, you won’t have adequate space
if the
vehicle ahead suddenly slows or stops. Keep back a
reasonable distance.
0 When it looks like a chance to pass is coming up,
start to accelerate but stay in the right lane and
don’t get too close. Time your move
so you will be
increasing speed as the time comes to move into the
other lane. If the way is clear to pass, you will have
a “running start” that more than makes up for the
distance you would lose by dropping back. And
if
something happens to cause you to cancel your pass,
you need only slow down and drop back again and
wait for another opportunity.
If other cars are lined up to pass a. slow vehicle, wait
your turn. But take care that someone isn’t trying to
pass you as you pull out to pass the slow vehicle.
Remember to glance over your shoulder and check
the blind spot.

of the right
lane to pass. When you are far enough
ahead of the passed vehicle to see its front in your
inside mirror, activate your right lane change signal and move back into the right lane. (Remember that
your right outside mirror is convex. The vehicle you
just passed may seem to be farther away from you
than it really is.)
Try not to pass more than one vehicle at a time
on two-lane roads. Reconsider before passing the
next vehicle.
Don’t overtake a slowly moving vehicle too rapidly.

Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don’t have enough friction where
the
tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to steer and
constantly seek an escape route or area of less danger.
Skidding
In a skid, a driver can lose control of the vehicle. Defensive
drivers avoid most
skids by taking reasonable care suited to
existing conditions, and by not “overdriving” those
conditions. But
skids are always possible.
The three types of skids correspond to your vehicle’s
three control systems. In the braking skid, your wheels aren’t rolling. In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip and
lose cornering force. And in the acceleration skid, too
much throttle causes the driving wheels to spin.
A cornering skid is best handled by easing your foot off
the accelerator pedal.
Remember: Any traction control system helps avoid
only the acceleration skid.
If your traction control system is
off, then an
acceleration skid is
also best handled by easing your
foot
off the accelerator pedal.

Downloaded from www.Manualslib.com manuals search engine Here are some tips on night driving.
0 Drive defensively.
0 Don’t drink and drive.
Since you can’t see as well, you may need to slow
down and keep more space between you and
other vehicles.
Slow down, especially on higher speed roads. Your
headlamps can light up only
so much road ahead.
0 In remote areas, watch for animals.
If you’re tired, pull off the road in a safe place
and rest.
Night Vision
No one can see as well at night as in the daytime. But as
we get older these differences increase.
A 50-year-old
driver may require at least twice as much light to see the
same thing at night as a 20-year-old.
What you do in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes
will have less trouble adjusting to night. But if you’re
driving, don’t wear sunglasses at night. They may cut
down
on glare from headlamps, but they also make a lot
of things invisible. You
can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to readjust to the dark. When you
are faced with severe glare (as from a driver who
doesn’t lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean
-- inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it’s easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim,
so should your eyes
be examined regularly. Some drivers suffer from night
blindness
-- the inability to see in dim li,ght -- and
aren’t even aware of it.

Downloaded from www.Manualslib.com manuals search engine City Driving Here are ways to increase your safety in city driving:
Know the best way to get to where you are
going. Get
a city map and plan your trip into an
unknown part of the city just as you would for a
cross-country trip.
Try to use the freeways that rim and crisscross most
large cities. You’ll save time and energy. (See the
next part, “Freeway Driving.”)
One
of the biggest problems with city streets is the
amount
of traffic on them. You’ll want to watch out for
what the other drivers are doing and pay attention to
traffic signals.
Treat a green light as a warning signal. A traffic
light is there because the comer is busy enough to
need it. When
a light turns green, and just before you
start to move, check both ways for vehicles that have
not cleared the intersection or may be running the
red light.

Mile for mile, freeways (also called thruways, parkways,
expressways, turnpikes or superhighways) are the safest
of all roads. But they have their own special rules.
The most important advice on freeway driving is: Keep
up with traffic and keep to the right. Drive at the same
speed most
of the other drivers are driving. Too-fast or
too-slow driving breaks a smooth traffic flow. Treat the left lane on a freeway as a passing lane. At
the entrance, there is usually a ramp that leads to the
freeway.
If you have a clear view of the freeway as you
drive along the entrance ramp, you should begin to
check traffic. Try
to determine where you expect to
blend with the flow.
Try to merge into the gap at close to
the prevailing speed. Switch on your turn signal, check
your mirrors and glance over your shoulder
as often as
necessary. Try to blend smoothly with the traffic flow.
Once you
are on the freeway, adjust your speed to the
posted limit or to the prevailing rate if it’s slower. Stay
in the right lane unless you want to pass.
Before changing lanes, check your mirrors. Then use
your turn signal.
Just before
you leave the lane, glance quickly over your
shoulder to make sure there isn’t another vehicle in your
“blind” spot.
Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect
to move
slightly slower at night.
When you want to leave the freeway, move to the proper lane well
in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.

Downloaded from www.Manualslib.com manuals search engine The exit speed is usually posted.
Here are some things you can check before a trip:
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go.
If it needs
service, have
it done before starting out. Of course,
you’ll find experienced and able service experts in
Cadillac dealerships all across North America. They’ll
be ready and willing to help if you need it.

Downloaded from www.Manualslib.com manuals search engine Highway Hypnosis
Is there actually such a condition as “highway hypnosis”?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch
of road with
the same scenery, along with the hum
of the tires on the
road, the drone of the engine, and the rush
of the wind
against the vehicle that can make you sleepy. Don’t let it
happen to you!
If it does, your vehicle can leave the
road in
less than a second, and you could crash
and be injured.
What can you do about highway hypnosis? First, be
aware that
it can happen.
Then here are some tips:
0 Make sure your vehicle is well ventilated, with a
comfortably cool interior.
0 Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and your
instruments frequently.
0 If you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.
