Your first aid kit for your car should include temporary fixes that you can use in case of an emergency.  The first part to this is with your tires.  One of the most caused break downs with cars is when a tire goes flat.  If you want to prevent this, you can make sure that your tires are filled with air before you drive.  If a problem does happen, you will want to make sure that you have a spare tire, jack to lift the car and a lug nut wrench in order to take off the hub cap and protective area on the tire. 

The second set of essentials for your car are just in case fluids.  It is always good to have a couple of extra quarts of oil, fluids for the engine, anti-freeze and even washer fluid.  If your car starts to over heat or something doesn't sound right while you are driving, you will have the ability to re-fill in order to get you to the next best point to stop at in order to see what is happening. 

Tools shouldn't just include the basic ingredients that will help your car get to the next stop.  You will also want tools in order to maneuver what is needed for your car.  Fuses, screwdrivers, pliers, vise grips, wrenches and even duct tape will all allow you to change what is needed into a temporary position.  By putting these into your kit, you will have the capacity to ensure that you get to the next place needed without having a complete breakdown. 

By combining the basics of your tools in your car, you will ensure that you don't get stuck, stopped or miss your destination point.  Knowing the basics of what to include and how this can help you on the road will allow you to define what is needed and will be able to provide you with the best options for ensuring that you stay safe, even when you are pulled off to the side of the road.
