Rule
30: Know How To Recover from a Skid
What's
the best way not to get into a skid? Avoid it in the first
place! One of the best ways to avoid trouble on the road (not
just skids) is to drive smoothly. True professionals drive
so seamlessly that you do not feel anything when they shift,
turn, or brake. Plan ahead, watch carefully, and slow down,
especially if you are unfamiliar with the road. Skids almost
always happen because the vehicle was running too fast for
conditions.
Be careful when conditions might be slippery,
as this is when most skids occur. But no matter what the road's
surface condition is, skids are caused by driver error. Try
to turn too sharply, enter a turn too quickly, or use excessive
acceleration or braking, and you'll get the chance to practice
skids! Keep your brakes maintained and properly adjusted,
because a lateral imbalance in your brakes can cause or aggravate
a skid.
There are two common types of skids. "Oversteer"
(or fishtailing) occurs when your front wheels are taking
a shorter path than desired and the rear-end breaks loose
and fishtails. This is the result of power and side forces
causing loss of traction on the rear wheels; there is too
much power applied for the existing steering input and the
resulting side forces cause the rear wheels to break free,
often as a result of trying to accelerate out of a turn. "Understeer"
(or plowing) occurs when you have too much steering input
for the power you are applying (too sharp an angle between
the tires and the direction of motion), and the front wheels
skid ahead as a result.
Professional driving instructors advise
a new way of teaching skid recovery, instead of the old rule,
which was, "Turn into the skid." They say this "new"
way is more understandable to non-professionals, but either
way, they adamantly say the result is the same. This change
was made because many folks didn't clearly understand what
"turn into the skid" means.
If you find yourself in an over-steer skid,
first thing to do is get off the gas, keep your foot off the
brakes, or smoothly release brake pressure if already applied,
and if you are driving a standard shift vehicle, disengage
the clutch. Quickly turn the steering wheel in the
direction you want the front of the car to go (down
the road). Specifically, this means align your tires with
the direction of your intended travel. As your vehicle
turns back in the correct direction, you must then counter
steer in time to stop the turning and stay on your desired
path. If you do not do this promptly, the vehicle will continue
to turn past your intended direction, and you may then skid
in that direction. You may have to counter-steer more than
once to get things under control.
[Editor's Note: There are two situations
where the previous techniques could actually make the skid
recovery more difficult. When you are driving either a front-wheel
drive vehicle or a rear-wheel drive with the four-wheel
drive engaged, a quick reduction on the accelerator can
cause a result in a loss of control that mimics what happens
when the brake pedal is depressed -- namely, the front wheels
are slowed faster than the rear wheels increasing the over-steer
skid problem. What is generally recommended is to place
the vehicle into neutral (or depress the clutch) to allow
the front wheels to coast as the vehicle is turned in the
direction described above. My own experience is that control
is much easier to reacquire by applying a steady pressure
on the gas pedal as one "drives" out of the skid,
but this assumes that the driver was traveling an appropriately
slow speed to begin with. Our thanks to reader L.N. from
York, PA, for reminding us of this issue.]
For an under-steer skid, slightly reduce
your steering input while slowing (without heavy braking)
so you'll regain your directional control as the tires again
grip the road surface. In this skid, the critical issue is
to reduce speed so that you can regain a grip on the road
and complete your turn. Even just a slight decrease in steering
input, combined with the reduction in speed, may be enough
to stop the skid from progressing.
These techniques are something you need to
practice. If there are any high performance driving schools
in your area, take advantage of the "safety" course
they offer and you'll get the opportunity to practice skid
recovery under safe, controlled conditions. You'll have a
better idea of what to do, and a better idea of your own capabilities
behind the wheel. I guarantee you will be a safer driver.
Keep the shiny side up!
