If trapped in a vehicle during a blizzard, what is the recommended action?

Running the engine about 10 minutes each hour is the recommended action if trapped in a vehicle during a blizzard. This practice helps to keep the engine running, which generates heat to maintain a warmer temperature inside the vehicle. Additionally, it allows occupants to stay warm without the risk of carbon monoxide buildup that can occur if the exhaust system is blocked by snow.

This action also ensures that the vehicle's battery remains charged, supporting any necessary electrical components for communication and safety lights. It is important to monitor fuel levels since running the engine uses gas, and being conservative with fuel can help maximize the duration of warmth.

The other actions—such as leaving the vehicle, opening the window for fresh air, or turning off all electronics—may increase the risk of hypothermia or leave occupants vulnerable to the elements and hazardous conditions outside, making them less suitable in such an emergency.
