What should you do if you're stuck in a blizzard to stay warm?

Running the engine for ten-minute intervals can indeed help maintain warmth in a blizzard situation. This method allows you to conserve fuel while providing heat intermittently. Keeping the vehicle's engine running generates warmth inside, which is crucial when outside temperatures are dangerously low. It's also important to ensure that the exhaust pipe is not blocked by snow to prevent carbon monoxide buildup inside the vehicle, allowing safe ventilation while still benefiting from the vehicle's heat.

In contrast, seeking shelter outside the vehicle can expose you to the elements and increase the risk of hypothermia. Staying still can conserve energy, but it does not adequately address the need for warmth. Opening the windows to let in fresh air is counterproductive in a blizzard, as it would allow cold air to enter the vehicle, lowering the internal temperature and increasing the risk of cold-related health issues. Therefore, running the engine for warmth while safely managing the conditions provides a practical approach to staying warm during a blizzard.
