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 U.S. 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 1 SO-pound or 82 kg person) has
doubled his or her chance of having an accident. At a
BAC level of
0.10 percent, the chance of that driver
having 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 need to take sudden action, as when a
child darts into the street?
A person with a higher BAC
might not be able to react quickly enough to avoid the
collision.

Off-Road Recovery
You may find sometime that your right wheels have
dropped off the edge of a road onto the shoulder while
you’re driving.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly
easy. Ease off the
accelerator and then, if there is nothing in the way, steer
so that your vehicle straddles the edge of the pavement.
You can turn the steering wheel up to
1/4 turn until the
right front tire contacts the pavement edge. Then turn
your steering wheel to go straight down the roadway.

Passing
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 ov’er your shoulder and check
the blind spot.

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 man one vehicle at a time on
two-lane roads. Reconsider before passing the next
vehicle.
Don’t overtake
a slowly moving vehicle too rapidly.
Even though the brake lights are not flashing,
it may
be slowing down or starting to
turn.
If you’re being passed, make it easy for the
following driver to get ahead
of you. Perhaps you
can ease a little
to the right.
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.
0 Check your mirrors, glance over your shoulder, and
start your left lane change signal before moving out
of the right lane to pass. When you are far enough In
any emergency, don’t give up. Keep trying to steer
and constantly seek an escape route or area of less
danger.

Driving at Night
rn
.. .
0 Adjust your inside rearview mirror to reduce the
glare from headlights behind you.
Since you can’t see as well, you may need to slow down
and keep more space between you and other vehicles.
0 Slow down, especially on higher speed roads. Your
headlights can light up only
so much road ahead.
0 In remote areas, watch for animals.
0 If you’re tired, pull off the road in a safe place and
rest.
Night Vision
Night driving is more dangerous than day driving. One
reason is that some drivers are likely to be impaired
-- by
alcohol or drugs, with night vision problems, or by fatigue.
Here are some tips on night driving.
0 Drive defensively.
0 Don’t drink and drive. 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
I 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 headlights, but they also make a lot
of things invisible.
You can be temporarily blinded by approaching lights. It
can take a second or two, or even several seconds, for
175
ProCarManuals.com

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.
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 headlights 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 headlights 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 light -- and aren’t
even aware
of it.
Driving in the Rain
Rain and wet roads can mean driving trouble. On a wet
road you can’t stop, accelerate or turn as well because
your tire-to-road traction isn’t as good
as on dry roads.
And,
if your tires don’t have much tread left, you’ll get
even less traction. It’s always wise to go slower and be
cautious
if rain starts to fall while you are driving. The
surface may get wet suddenly when your reflexes are
tuned for driving
on dry pavement.

Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road is wet enough and you’re
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with
the road.
Hydroplaning doesn’t happen often. But it can
if your
tires haven’t much tread or if the pressure in
one or
more is low. It can happen if a lot of water is standing
on the road. If you can see reflections from trees,
telephone poles, or other vehicles, and raindrops
“dimple” the water’s surface, there could be
hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn’t a hard and fast rule about hydroplaning. The
best advice is
to slow down when it is raining.

Turn on your low-beam headlights -- not just your
parking lights
-- to help make you more visible to
others.
Besides slowing down, allow some extra following
distance. And be especially careful when
you pass
another vehicle. Allow yourself more clear room
ahead, and be prepared
to have your view restricted
by road spray.
Have good tires
with proper tread depth. (See
“Tires” in the Index.)
