Auto insurance protects you against financial loss if you have an accident. It is a contract between you and the insurance company. You agree to pay the premium and the insurance company agrees to pay your losses as defined in your policy. Auto insurance provides property, liability and medical coverage:

1. Property coverage pays for damage to or theft of your car.
2. Liability coverage pays for your legal responsibility to others for bodily injury or property damage.
3. Medical coverage pays for the cost of treating injuries, rehabilitation and sometimes lost wages and funeral expenses.

An auto insurance policy comprises six kinds of coverage. Most countries require you to buy some, but not all, of these coverages. If you're financing a car, your lender may also have requirements. Most auto policies are for six months to a year.

In the United States, your insurance company should notify you by mail when it’s time to renew the policy and to pay your premium.
