Quick Answer
Sleeping in the car may be a viable option for short periods, but it's essential to consider factors such as vehicle preparation, clothing, and health.
Vehicle Preparation
If you’re stranded in a snowstorm, your vehicle can provide some protection from the elements. However, it’s crucial to ensure your car is ready for the situation. Check the following before attempting to sleep in your vehicle: the engine is turned off and the parking brake is engaged, the windshield and windows are clear, and the interior temperature is maintained by using the cabin heater or a portable heater (if equipped). Additionally, consider keeping a blanket, emergency blanket, or a space blanket in your vehicle for insulation.
Clothing and Personal Gear
To stay warm while sleeping in your vehicle, wear layers of clothing, including a hat, gloves, and socks. Consider keeping a change of clothes in your vehicle, including a warm hat and gloves. Bring a sleeping bag or emergency bivvy sack to retain body heat. If you have a portable heater, use it to maintain a safe interior temperature. Keep a supply of non-perishable snacks and water nearby to stay hydrated and energized.
Safety Considerations
Be aware of the potential risks associated with sleeping in a vehicle during a snowstorm: carbon monoxide poisoning from a malfunctioning heater, hypothermia from cold temperatures, and frostbite from exposure to cold surfaces. Monitor your vehicle’s exhaust system for signs of carbon monoxide buildup. If you’re experiencing any symptoms such as dizziness, headaches, or nausea, exit the vehicle immediately and seek fresh air. Limit your time in the vehicle to a maximum of 8-10 hours, and consider finding alternative shelter if possible.
