Vehicle preparation and safety precautions for winter weather
Stay in your vehicle
- Disorientation occurs quickly in wind-driven snow and cold.
- Run the motor about 10 minutes each hour for heat.
- Open the window a little for fresh air to avoid carbon monoxide poisoning.
- Make sure the exhaust pipe is not blocked.
- Make yourself visible to rescuers.
- Turn on the dome light at night when running engine.
- Tie a colored cloth (preferably red) to your antenna or door.
- Raise the hood indicating trouble after snow stops falling.

- Wear a hat; half your body heat loss can be from the head.
- Cover your mouth to protect your lungs from extreme cold.
