If you become stuck in a heavy snowstorm, what should you attach to your antenna or door handle?

Answer: C — Red cloth

Attaching a red cloth to your antenna or door handle is an effective way to signal your distress when you are stuck in a heavy snowstorm. The color red is universally recognized as a signal for danger or a need for assistance. This is particularly important in severe weather conditions where visibility is low, and rescuers may have difficulty finding you. A bright and noticeable color like red stands out against the snowy background, making it easier for others to spot your vehicle from a distance. This simple action can significantly improve the likelihood of receiving help in a timely manner when you're in a precarious situation.
