Driving is a privilege, but it comes with a price tag. There's the cost of the vehicle itself, maintenance, repairs, fuel and auto insurance. Many states require you to carry a basic, minimum level of auto insurance. It's a way of sharing the risks of driving.  You pay premiums to an insurance company for coverage. In return, your coverage will protect you against most financial losses that might otherwise be your responsibility to pay. 

Auto insurance is more than a matter of insuring your vehicle for loss or repairs after an accident.

These are usually called assigned risk plans, joint underwriting associations or reinsurance facilities (see Assigned Risk, above).

Bodily Injury Liability.  Coverage that protects you against financial loss and pays legal defense costs when you are legally liable for injuring other persons in an auto accident.

Subject to a deductible.

Coverage.  Indicates the type of coverage and/or the protection your insurance policy will provide.

Deductible.  The amount you must pay before your insurance coverage begins paying.

However, if the loss were less than or equal to $250, you would pay the entire amount and the insurance company would pay nothing.

Depreciation.  The decrease in the value of your car or its parts due to age and general wear-and-tear.
