Your anti-lock brakes improve your ability to make a hard stop on a
slippery road.
Even
though you have an anti-lock braking system, you'll
want to begin stopping sooner than
you
would on dry pavement. See
"Anti-Lock" in the Index.
Allow greater following distance on any slippery road.

Watch for slippery spots. The road might be fine until you hit a spot
that's covered with ice. On an otherwise clear road, ice patches may
appear in shaded areas where the sun can't reach: around clumps of
trees, behind buildings, or under bridges. Sometimes the surface of a
curve or an overpass may 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're actually on the ice, and avoid sudden
steering maneuvers.
If You're 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 your
hazard flashers. Tie a red cloth to your vehicle to alert police that you've
been stopped by the snow. Put on extra clothing or wrap a blanket around
you. If you have no 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.
You can run
the
engine to keep warm, but be careful.
