Why is the average cost of car insurance so different from state to state? Because each state has different car insurance laws, accident rates and property crime statistics.

Also, what you pay for auto insurance may be more or less than the average rates for your state. This is because insurance companies consider several rate factors like your age, gender and what kind of car you drive to come up with your premium.
