Stay in the vehicle, run the engine about 10 minutes each hour, open a window slightly and keep the exhaust pipe clear of snow to avoid carbon monoxide, and signal for help.
Stay with the vehicle
The NWS says if you get stranded, stay with your vehicle and wait for help to arrive. Stay in the vehicle because wind-driven snow and cold can quickly disorient you if you leave.
Heat and carbon monoxide
Run the engine about 10 minutes each hour for heat. When running a vehicle for heat, open a window slightly for fresh air to avoid carbon monoxide poisoning, and clear snow from the exhaust pipe.
Signal for help
At night, turn on the dome light while the engine runs. Tie a bright cloth, preferably red, to the antenna or door. After the snow stops falling, raise the hood to signal that you need help.
Avoid overexertion
The NWS warns against overexertion, including pushing a car or walking in deep snow, especially if you are not in good health. Cold and hard labor can cause a heart attack, and sweating can lead to a chill and hypothermia.
Be ready before you go
Carry a winter survival kit. See our guide on the winter car kit.
