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.
