The Anti-Lock Brake System (ABS) improves your
vehicle's stability when you make a hard stop
on a slippery road. Even though you have ABS,
you want to begin stopping sooner than you would
on dry pavement. See Anti-Lock Brake System
(ABS) on page 335.
•
Allow greater following distance on any
slippery road.
•
Watch for slippery spots. The road might be
fine until you hit a spot that is covered with
ice. On an otherwise clear road, ice patches
may appear in shaded areas where the
sun cannot reach, such as around clumps of
trees, behind buildings, or under bridges.
Sometimes the surface of a curve or an
overpass can remain icy when the surrounding
roads are clear. If you see a patch of ice
ahead of you, brake before you are on it.
Try not to brake while you are actually on the
ice, and avoid sudden steering maneuvers.

If You Are Caught in a Blizzard
If you are stopped by heavy snow, you could be in
a serious situation. You should probably stay with
your vehicle unless you know for sure that you
are near help and you can hike through the snow.
Here are some things to do to summon help
and keep yourself and your passengers safe:
•
Turn on the hazard flashers.
•
Tie a red cloth to your vehicle to alert police
that you have been stopped by the snow.
•
Put on extra clothing or wrap a blanket
around you. If you do not have blankets
or extra clothing, make body insulators
from newspapers, burlap bags, rags, floor
mats — anything you can wrap around
yourself or tuck under your clothing to
keep warm.
