Your vehicle should also have a first aid kit with gloves, bandages, pain relievers, saline solution for washing contaminants out of your eyes, ointment, disinfectant, a digital thermometer, and other basic supplies. If you take prescription medication, keep 1-2 doses in your vehicle in case you become stranded. Hot and cold packs that you can bend to activate will help you stay comfortable while waiting for help. An easy-to-follow first aid manual will help you and your passengers understand what to do in an emergency.
