What action should you take when trapped in a vehicle after a blizzard?

When trapped in a vehicle after a blizzard, it is crucial to make your vehicle as visible as possible to rescuers. Hanging a brightly colored cloth on the radio antenna serves this purpose effectively. It signals to those searching for you that you are in need of assistance and provides a clear visual indicator, especially in a setting where snow can obscure visibility.

Aside from visibility, remaining in your vehicle is often advised during severe winter conditions, as it provides shelter from the elements and increases your chances of being found. Utilizing signaling methods like a brightly colored cloth, along with other strategies like keeping the engine running intermittently to stay warm (while ensuring the exhaust pipe is clear), enhances your survival chances during such emergencies.
