Quick Answer
Start the car and let it run, but crack a window for ventilation to prevent carbon monoxide poisoning. This will also help you stay warm, but be cautious of the wind and your visibility. Move to the center of the back seat if possible.
Engine and Ventilation
If you’re stranded in a car during a blizzard, it’s crucial to start the engine and let it run. However, it’s equally important to take steps to prevent carbon monoxide (CO) poisoning. Open a window, but not fully, to allow for proper ventilation. A 1-2 inch gap is sufficient to allow CO to escape while keeping the cold air out. This will also help to reduce the risk of hypothermia.
Staying Warm
Staying warm is essential in extreme cold weather. The American Red Cross recommends keeping your body temperature above 95°F (35°C) to avoid hypothermia. You can achieve this by wearing warm clothing, using blankets, or turning up the car’s heating system. However, be cautious not to overexert yourself by trying to fix the car or venture out into the blizzard.
Visibility and Safety
Visibility is critical when stranded during a blizzard. Keep the windshield wipers on intermittent mode to reduce the risk of ice buildup. If you’re unable to see the road, do not attempt to move. Instead, wait for the storm to pass or until help arrives. Keep your phone charged and use it to call for assistance or send a distress signal. If you have a portable charger, use it to keep your phone powered up.
