. Road Signs
The road signs you see everywhere are
coded
by color, shape and symbols. It's
a good idea to know these codes so that
you can quickly
grasp the basic meaning
or intent
of the sign even before you
have a chance to
read it.
Color of Road Signs
WRONG
WAY,
Red means Stop. It may also indicate
that some movement
is not allowed.
Examples are
Do Not Enter and
Wrong Way.
Green is used to guide the driver.
Green signs
may indicate upcoming
freeway exits or show the direction you
should turn to reach a particular place.
Yellow indicates a general warning.
Slow down and be careful when you see
a yellow sign. It may signal a railroad
crossing ahead, a no passing zone, or
* some other potentially dangerous
situation. Likewise,
a yellow solid line
painted
on the road means Don't
Cross.

Corvette ASR System (CONT.)
The ASR system comes on when the
ignition is -turned
on and operates at all
speeds. When your ASR system is
operating, the
ASR ACTIVE indicator
on the Driver Information Center
(DIC)
will come on. It indicates the system
has detected excess wheel slip, like the
conditions found on slippery-roads.
Also, when ASR is active, the cruise
control
will be automaticaIly turned off
The SERVICE ASR warning light lets
you know
when there is a problem with
your ASR system. When this light is on,
you have no-automatic wheel spin
protection. Adjust your driving
accordingly, See the
Index under
Service ASR Light..
Turning the ASR System Off
To limit wheel spin, especially in
slippery road conditions, you should
always leave your ASR. system on. But
you can turn the ASR system off if you
ever need to. ASR OFF means the
controller is passive, but still
monitoring wheel
speed informauon.

Myht Vision
No one can see as well at night, as in the
daytime. But as
we get older -these
differences increase. A. 50-year-ald driver may require .at least twice as
much light to see the same thing at
night as a 20-year-old.
What you 80 in the daytime can also
&ct your night vision. For example, if
you spen-d-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 headlights, but they also
make
a lot of things invisible that
should
r.enmin visible-such as parked
cars, obstacles, pedestrians, or even
trains blocking railway
crossings.. You
may want to put on your sunglasses
after you have pulled into a brightly
lighted service or refreshment area.
Eyes shielded from that glare may
adjust more quickly to darkness back
on the road, But be sure to remove your
sunglasses before
you .leave the service
area.
You can be temporarily blinded by
approaching lights. 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
headlights),
slow down a little. Avoid
-staring directly into the approaching
lights. If there is a line of opposing
traffic, make occasional glances
over the
line of headlights to make certain that
one
of the vehicles isn’t starting to
move into your lane. Once you .are past
the bright lights, give your eyes time
to
readjust before resuming speed.
High Beams
If the vehicle approaching-you has its
high beams on, signal by fliclcing yours
to high and then back to low beam. This
is the usual signal to lower the
headlight beams. zf.the other
driver still
doesn’t lower the
beams, resist the
ternaptation to. put
your high beams on.
This only makes two ha-blinded
drivers.
On a freeway, use your high beams only
in remote axeas where you won’t impair
approaching drivers.
In some p€aces,
like cities, using high beams is illegal.
When you follow another vehicle on a
freeway
or highway, use low beams.
True, most vehicles
now have day-night
mirrors that enable the driver to reduce
glare. But outside
mirrors are not of this
type and high beams
from behind can
bother the driver ahead.

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.
