Our 4 Person Standard Car Survival Kit supports 4 people for 3 days. This kit includes all the emergency food, water, shelter, sanitation, first aid, lighting, and communication supplies necessary for car emergency preparedness. Remember, after a disaster, stores will be closed! Roads will be down! And you may have to get out of your car and travel great distances by foot to get to a safe or familiar location. You need to be self-sufficient.
