If You're Caught in a Bli'ard 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 andyou can hike through the snow. Here are some things todo 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 stoppedby 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 tuck or under your clothing to keep warm. You can run the engine to keep warm, but be careful. cause deadly CO (carbon monoxide) gas toget 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 baseof your vehicle, especially any that is blocking your exhaust pipe. And check around again from timeto time to be sure snow doesn't collect there. Open a windowjust a little on the side of the vehicle that's awayfrom the wind. This will help keep CO out.
