In the unfortunate event that your car has mechanical problems during your road trip, be sure that you have the necessary tools and services at your disposal. Flat tires are a common and easy-to-address problem that drivers face while on the road. Before you leave for your trip, locate your jack and tire iron, and learn how to use them. Also make sure that your spare tire is fully inflated so you can drive on it safely. If car mechanics is not your cup of tea, you might consider subscribing to a roadside rescue service like AAA. Such companies will send someone to change your flat tire, provide a jump start, bring you gasoline if you run out, and open your car if you become locked out.
It's also a good idea to carry a basic toolkit to fix simple problems you may encounter. Some good items to include are a hammer, a rubber mallet, an adjustable wrench, screwdrivers, wire cutters, a pair of needle-nose pliers, some baling wire, a can of WD-40 and a rag.
