when the three control systems (brakes, steenng and
acceleration} don't have enough Inction where the lires
mset the road to do what the driver has asked.
tn any emergency, don’t give up. Keep trying to steer
and constantly seek an escapo route or area ot
less danger
Skidding
fri a skid, a driver can lose control of The vehicle.
Deiensive drivers avoid most skids by lahirtg reasonable
care suited toeiristing conditions, and by not "overdriving"
those conditions. But skids are always possibieb
Tho throe types of skids correspond to yotrr vehicle's
three corrirol systems, In the braking skid, your wheels
aren't rolling^ In the ottering or сото ring skid, too rouch
speed or steering in a curve causes Tires to slip and lose
cornering force. And in the acceleration skid, loo much
throttle causes the driving wheels lo spin,
A Cornenng skid Is host handled by easing your fool Ctf
the accelerator pedal.

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

gravet or other material is on the road. For safety, you'll
want to slow down and adfust your driving to these
conditions. It IS importani to slow down on slippery
surfaces because stopping distance will bq tongor end

While driving on a surface with reduced traction, iry
your best to avcud sudden steering, acceleration
or braking (including engine braking by shitting to a
lower gear). Any sudden changes could oausE the tires
tu slide. You may not realise 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 lo make a “mirrored surface" — and slow
down when you have any doubt.

avoid only the braking skid.
