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.

Tips on Driving in Fog (CONT.)
something between you and moving
vehicles-space, trees, telephone poles,
a private driveway, anything that
removes you
from other trafic.
If visibility is near zero and you must
stop but are unsure whether you are
away
from the road, turn your lights on,
start your hazard warning flashers, and
sound your horn at intervals or when
you hear approaching traffic.
Pass other vehicles in fog only if you
can see far enough ahead to pass safely.
Even then, be prepared to delay your
pass if you suspect the fog is worse up
ahead. If other vehicles try to pass you,
make it easy for them.
City Driving
One of the biggest problems with city.
streets
is the amount o€ traffic on them.
You’ll want to watch
out for what the
other drivers are doing
and pay
attention
to traffic signals.
Here are ways to increase your safety in
city driving:
* Know the best way to get to where
you-are going.
Try not to drive around
trying to pick out a familiar street or
landmark. Get a city map
and plan
your trip into an unknown part of the
city
just .as you would for a cross-
country trip.
9 Try to use the freeways that rim and
crisscross
most large cities. You’ll
save time
and energy. (See the next
section,
Freeway Driving.)
Treat a green light as a warning
.signal, A traffic light is there because
the corner
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.
Obey all posted speed limits. But

and visibility conditions. You

Freeway Driviing
Mile--for mile, .freeways (also called
thruways,
parkways, -expressways,
turnpikes,'
or superhighways) are the
safest of all roads. But they have their
own specid rules.
The most important advice on freeway
driving is: Heep.up with tretffic and keep
to the right. Drive at the same speed
most of the ,ot.her drivers are driving-.
Too-fast :or too-slow driving breaks a
mo'oth traffic flow. Treat the left €me
on a :freeway as :a passing lane.

Entering the Freeway
At the entrance 'there' is usually a ramp

clear view of the h.my as you drive
along thr: entrance ramp, you .shmild

as necessary. 'Try to blend smoothly

DrJvfng on the Freeway
Once you are on the freeway, adjust
your speed
to the posted limit or to,the
prekbg rate if it's slower. Stay in
right fane unless you want to pass. If
you are ma two-lme freeway; treat the
right lane as the sbw lane and the,left
lane the passing lane.
If you are on a thee-lane freeway, treat
the right-
lane as the. slower-speed
through lane, the middle €ane as the
higherdpeed through lane, and the left
lane -as the passing .. lane.
Before changing lanes, check your
rearview minors. Then use YOU turn

Driving a Long Distance
Although most long trips today are
made on freeways, there are still many
made
on regular highways.
Long-distance driving
on freeways and
regular highways is the same in some
ways. The trip has to be planned and
the vehicle prepared, you drive at
higher-than-city speeds, and there are
longer turns behhd the wheel. You’ll
enjoy your
trip more if you and your
vehicle
are in good shape. Here are
some.fips for
a successful long trip.
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 Chevrolet dealerships all
across North America. They’ll be ready
and willing to help if you need it. Here
&e some
things you can check
before
a trip:

On She Road
Uidess you are the -only driver, it is good
to share the driving task with others.
Limit turns behind
the wheel to about
100 miles (160 km) Or two hours at a
sitting.-Then, either change drivers ar
stop for some rdreshment like coffee,
tea or
soft drinks and some limbering
up.
But do stop and move around. Eat
lightly along the way. Heavier meals
tend to
mdke some people sleepy.
On two-lane highways or
undivided
multilane highways that do not have
controlled .access,.you’ll
wmt to watch
for some situations :not usustlly found
on freeways. Examples: are: stop signs
and signals, shopping tenters with
direct access
to the highway, no passing
zones and school zones, vehicles
turning
le& and- right off the-road,
pedestrians, cyclists, parked vehicles, and even a&&.
Highway Hypnosis
Is thete-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:
4 Make sure your vehicle is well
ventilated,
with a comfortably cool
interior.
Keep your eyes moving. Sca.n the road
ahead and
-to the sides. Check your
rearview mirrors frequently and your
instruments from time to time. This
can help you avoid
a fixed stare.
Wear good sunglasses in bright light.
Glare can cause drowsiness. But
don’t
wear sunglasses at night. They will.
drastically reduce-your,overall.~sion
at the very time you need all the.
seeing power
you have.
If you get sleepy, pull off the road into
a rest, service, &‘parking area and
take a nap, get so.me exercise, or both.
For safety, treat drowsiness on the
highway
as an emergency.
As in any driving situation, keep pace
with traffic and allow adequate
foIlowing distances.
