(HealthDayNews) -- A winter storm can always become more severe than forecast. If a blizzard traps you in your car, the U.S. Federal Emergency Management Agency advises you:
- Pull off the road, set hazard lights to flashing, and hang a distress flag on the radio aerial or window. And stay in your car.
- Conserve gas, but run the engine and heater about 10 minutes each hour to keep warm. Open a window slightly to prevent carbon monoxide poisoning. Exercise to maintain body heat, but don't overdo it. Huddle with other passengers and use your coat for a blanket.
- In extreme cold use road maps, seat covers, floor mats, newspapers and clothing for covering.
- Turn on the inside dome light so rescuers can see you at night. In remote areas, spread a large cloth over the snow to attract the attention of rescue planes.
- Don't set out on foot unless you can see a building nearby.
