Control Of A Vehicle; Braking - Chevrolet 2011 Corvette Coupe Owner's Manual

For persons under 21, it is against
the law in every U.S. state to drink
alcohol. There are good medical,
psychological, and developmental
reasons for these laws.
The obvious way to eliminate the
leading highway safety problem is
for people never to drink alcohol
and then drive.
Medical research shows that
alcohol in a person's system
can make crash injuries worse,
especially injuries to the brain,
spinal cord, or heart. This means
that when anyone who has been
drinking driver or passenger
in a crash, that person's chance of
being killed or permanently disabled
is higher than if the person had not
been drinking.

Control of a Vehicle

The following three systems
help to control the vehicle while
driving brakes, steering, and
accelerator. At times, as when
driving on snow or ice, it is easy to
ask more of those control systems
than the tires and road can provide.
Meaning, you can lose control of
the vehicle. See

Adding non dealer accessories can
affect vehicle performance. See

Braking

See
.
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time.
Driving and Operating
Average reaction time is about
three fourths of a second. But
that is only an average. It might be
less with one driver and as long as
two or three seconds or more with
another. Age, physical condition,
alertness, coordination, and
eyesight all play a part. So do
alcohol, drugs, and frustration.
But even in three fourths of a
second, a vehicle moving at
and
100 km/h (60 mph) travels
20 m (66 feet). That could be a lot
of distance in an emergency, so
keeping enough space between
the vehicle and others is important.
And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition
of the road, whether it is wet, dry,
or icy; tire tread; the condition of the
brakes; the weight of the vehicle;
and the amount of brake force
applied.
