1. A spare tire

2. Triangle reflectors (to place on the road and indicate to other drivers that you are having a little car trouble)

3. Tools (a jack, bolt loosener / tightener, WD40, screwdrivers, extra lightbulbs, fuses, a flashlight, portable tire pump, extra air valves for tires)

4. Security measures (This can be anything from a taser to anything licensed by the police for your own personal protection from robberies and what not.)

5. Car manual (It’s doubtful that you know every square inch of your vehicle. Don’t leave home without this.)

6. A spare battery (only if you have the budget and the extra space in the trunk)

7. An emergency fire blanket

8. Miscellaneous oils and greases (brake fluid, engine oil, extra gas in a gas can, power steering fluid, engine coolant)

9. Cleaning solutions (car wax, glass cleaning liquids, a spray can, clean and dry rags)

10. Emergency light (A flashing bright light, like a strobe, is definitely something you may need especially if you are one who drives long distances at night. This will grab the attention of anybody within range.)
