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.
In
any
emergency, don't give up. Keep trying to steer and constantly seek an
escape route or area of less danger.
In a skid, a driver can lose control of the vehicle. Defensive drivers avoid
most skids by taking reasonable care suited to existing conditions, and by
not "overdriving" those conditions. But skids are always possible.
The three types of skids correspond to your vehicle's three control systems.
In
the braking skid your wheels aren't rolling. In the steering or cornering
skid, too much speed or steering in a curve causes tires to slip and lose
cornering force. And in the acceleration skid too much throttle causes the
driving wheels to spin.
H
cornering skid and an acceleration skid are best handled by easing your
foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the accelerator pedal and
quickly steer the way you want the vehicle to go. If you start steering
quickly enough, your vehicle may straighten out. Always be ready for a
second skid if it occurs.
Of course, traction is reduced when water, snow, ice, gravel, or other
material is on the road. For safety, you'll want to slow down and adjust your
driving to these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and vehicle control more
limited.
While driving
on a
surface with reduced traction,
try
your best to avoid
sudden steering, acceleration, or braking (including engine braking by
shifting
to
a lower gear). Any sudden changes could cause the tires to slide.
You may not realize the surface is slippery until your vehicle is
skidding.
Learn to recognize warning clues
-
such as enough water, ice or packed
snow on the road to make a "mirrored surface"
-
and slow down when you
have any doubt.
Remember: Any anti-lock brake system (ABS) helps avoid only the braking
skid.
