Many  everyday vehicle problems can be resolved with a little proactive prevention and preparation.  For instance it is wise to never let your vehicle get below a quarter of a tank before filling it up.  This will help you should you find yourself stuck in bumper to bumper traffic, or on a long trip in the middle of nowhere.  You will not have to worry about running out of fuel.  Keeping a spare key hidden in your house will save you a lot of money and aggravation if you should lose yours.  It can be less costly to get a duplicate key made from an existing key rather than having a locksmith make a trip out and create a key.  Ensuring that your spare is inflated at all times and you have a basic tire repair kit both can save headaches.  Of course all your emergency repair items should be maintained and in good working order.
