ALWAYS be careful about poisonous fumes in or near your car. Follow ALL manufactures’ warning and other best practices when running engines, using candles and other sources of heat in or near your vehicle.
Cars are a great source of protection from the elements when equipped with as many essential items as space and circumstance permit. Remember, to always have medication for yourself and for those who travel with you.
With a little planning, your car can provide you with a warm, dry and safe location to ride out certain events. Due to the radio and power it provides to smart devices (remember to have chargers and cords for them), it also provides news updates and light. Depending on state or provincial laws, you may also be able to have a firearm and ammunition with you.
Make sure headlights, parking lights and any interior dome lights are off when vehicle is not running. They can drain a car battery very quickly. Same for the radio and any phones or tablets you may have plugged in. If you are stuck in a snowstorm, always remember to keep the car exhaust area free of snow and always keep brushing off rear and front headlights so people can see you if needed. Keep doors and windows free of ice and snow as well.
Have in your car at all times a bag with a change of clothing. Clothing should be changed out per season and be similar to hiking or rugged wear. Keep the colors plain as you do not want to stand out. So greys, browns, tan work fine but just no bright reds or yellows and of course no camo. Only time you would think of camo is if you are considering or being forced to go trooping through fields and bush. You also want good hiking boots, hiking socks, comfortable underwear, hat, gloves, jacket and raingear.
Water in a car in cold climes can be an issue. You can purchase small packs of water used for survival situations and they are usually good down to minus forty degrees Fahrenheit. You can also use bottled water but only if you empty some of the water out so when they freeze up, the water has room to expand! Take a bottle and empty about one inch of water, tighten cap back on and pop in your freezer and see if it is ok when frozen. Adjust water levels until you know you have the correct level when they are frozen and then store in upright position.
If space permits, try having at least 8 liters of water with you in the car at all times and keep in a tote or similar bag. This is in addition to what is in your 12, 24 or 72 hour car bag.
