Survival Guide: Staying Warm in a Car During a Blizzard
Being stranded in a vehicle during a winter storm is one of the most dangerous scenarios a commuter or traveler can face. When the temperature drops and visibility hits zero, your car becomes your only life pod. Here is how to manage your body heat and resources to survive until help arrives.
1. Immediate Actions: Insulate Your Shelter
Your vehicle is a metal box that loses heat rapidly. To slow this process:
- Seal the Windows: Stuff clothing, floor mats, or newspapers into the gaps between the seats and the doors.
- Conserve Space: If you are alone, move to the backseat and hang blankets or coats over the front seats to create a smaller “cabin” to heat with your body.
- Stay Dry: Wet clothes are the fastest way to hypothermia. If your clothes are damp from trying to push the car, change into dry spares immediately.
2. The Engine & Carbon Monoxide Rules
You can run the engine for heat, but you must do it safely.
CRITICAL SAFETY: Before starting the engine, ensure the exhaust pipe is completely clear of snow. A blocked tailpipe will send deadly carbon monoxide into the cabin.
- Run the engine for only 10–15 minutes every hour.
- While the engine is running, turn on the heater and keep a dome light on so rescuers can see you at night.
- Crack one window slightly on the downwind side to allow fresh air circulation while the engine is running.
3. Essential Gear for Your Winter Car Kit
The difference between discomfort and disaster often comes down to what you have in your trunk. We recommend these specific items for every winter emergency kit:
- Mylar Emergency Blankets: These reflect 90% of your body heat back to you and are windproof and waterproof.
- Rechargeable Hand Warmers: Much more effective than disposable ones for long durations.
- Wool Blankets: Unlike cotton or synthetics, wool retains heat even when wet.
- Emergency Candles: A simple “Survival Candle” can actually raise the temperature inside a car by several degrees.
4. Body Heat Management
If you are traveling with others, huddle together. If alone, perform light exercises (moving your arms and legs) to stimulate circulation, but do not overexert yourself to the point of sweating.
Pro Tip: Keep a high-calorie “emergency food” stash in your glove box. Your body needs fuel to generate heat; high-fat items like peanut butter or energy bars are ideal.
5. Signal for Help
Do not leave the vehicle to walk for help unless you can see a building within 100 yards. In a blizzard, it is incredibly easy to lose your orientation and perish just feet from safety.
- Tie a bright cloth (ideally red or orange) to your antenna or window.
- Keep your phone charged using a portable power bank.
Stay safe. Stay prepared.
