Your Driving and the Road
Steering Tips-Driving on Curves
It’s important to take curves at a
reasonable speed.
A lot of the “driver lost control”
accidents mentioned on the news
happen on curves. Here’s why:
Experienced driver or beginner, each of
us
is subject to the same laws of physics
when driving on curves. The traction of
the tires against the road surface makes
it possible for the vehicle to change its
path when you turn the front wheels. If
there’s
no traction, inertia will keep the
vehicle going in the same direction. If
you’ve ever tried to steer a vehicle
on
wet ice, you’ll understand this.
The traction you can get in a curve
depends on the condition
of your tires
and the road surface, the angle at which
the curve
is banked, and your speed.
While you’re in
a curve, speed is the one
factor you can control.

Suppose you’re steering through a
sharp curve. Then you suddenly apply
the brakes. Both control systems-
steering and braking-have to do their
work where the tires meet the road.
Unless you have four-wheel anti-lock
brakes, adding the hard braking can
demand too much at those places. You
can lose control.
The same thing can happen
if you’re
steering through a sharp curve and you
suddenly accelerate. Those two control
systems-steering and acceleration-
can overwhelm those places where the
tires meet the road and make you lose
control.
What should you do if this ever
happens? Let up on the brake or
accelerator pedal, steer the vehicle the
way you want it to go, and slow down. Speed limit signs near curves
warn that
you should adjust your speed. Of
course, the posted speeds are based on
good weather and road conditions.
Under less favorable conditions you’ll
want to
go slower.
If you need to reduce your speed
as you
approach a curve, do it before you enter
the curve, while your front wheels are
straight ahead.
Try to adjust your speed
so you can “drive” through the curve.
Maintain a reasonable, steady speed.
Wait to accelerate until you are out
of
the curve, and then accelerate gently
into the straightaway.
When you drive into a curve at night,
it’s harder to see the road ahead of you
because it bends away from the straight
beams
of your lights. This is one good
reason to drive slower.

Your Driving and the Road
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 ‘/4
turn until the right front tire contacts
the pavement edge. Then turn your
steering wheel to go straight down the
roadway.
If the shoulder appears to be about four
inches (100 mm) or more below the
pavement, this difference can cause
154
problems. If there is not enough room
to pull entirely onto the shoulder and
stop, then follow the same procedures.
But
if the right front tire scrubs against
the side
of the pavement, do not steer
more sharply. With too much steering
angle, the vehicle may jump back onto
the road with
so much steering input
that it crosses over into the oncoming
traffic before you can bring it back
under control. Instead, ease
off again on
the accelerator and steering input,
straddle the pavement once more, then
try again.
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:
“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.
