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 toalert 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 yourselfor tuck under your clothing to keep warm. You can run the engine to keepwarm, but be careful. I -C L A a Snow can trap exhaust gases L under your vehicle.This can cause deadly CO (carbon monoxide) gas to get inside.CO could overcome you and kill you. You can't see it or smell it, so you might not know it was in your vehicle. Clear away snow from around the base of your vehicle, especially any that is bloclng your exhaust pipe. And check around again from time to time to besure snow doesn't collectthere. Open a window just a little on the side of the vehicle that'saway from the wind. This will help keep CO out.
