Your car is likely one of the most expensive things you own. Insurance protects your investment and guarantees you a way of coping with the expense of accidents, vandalism or theft. It also secures your financial responsibility to the institution lending you money to buy your vehicle.
When you drive you are responsible for the safety of your passengers, your fellow drivers, other peoples property, pedestrians and yourself. Insurance helps ensure your ability to cover the costs of potential damages or injuries.
You are also required to be financially responsible by state laws, which are best satisfied through your insurance coverage. In most states insurance is a prerequisite to registering your car. So if you want to drive your own vehicle, you must be insured.
