Skidding
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 the vehicle’s three control
systems. In the braking skid, the
wheels are not 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.
If the 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,
the 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,
slow down and adjust your
driving to these conditions. It is
important to slow down on slippery
surfaces because stopping
distance is 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 reducing vehicle
speed by shifting to a lower gear.
Any sudden changes could cause
the tires to slide. You might not
realize the surface is slippery until
the 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 Antilock Brake
System (ABS) helps avoid only the
braking skid.
Driving at Night
Night driving is more dangerous than
day driving because some drivers
are likely to be impaired — by alcohol
or drugs, with night vision problems,
or by fatigue.
Night driving tips include:
• Drive defensively.
• Do not drink and drive.
• Reduce headlamp glare by
adjusting the inside rearview
mirror.
• Slow down and keep more space
between you and other vehicles
because headlamps can only
light up so much road ahead.
• Watch for animals.
• When tired, pull off the road.
• Do not wear sunglasses.
• Avoid staring directly into
approaching headlamps.
