A study by the National Association of Insurance Commissioners says Iowa still has the lowest car insurance rates in the country. Angela Burke-Boston of the Iowa Insurance Division says the rank is based on a variety of factors. They consider our population, repair cost, theft rates, and the number of registered vehicles. Under the system used by the study, Iowa’s average premium was just over 596-dollars. Burke-Boston says Iowa likely has fewer claims than other states, which also helps the ranking. She says she can’t tell that from the study, but it’s probably safe to say that we have fewer bodily injury claims. She says the competition among companies in Iowa keeps the cost of insurance down. She says we have over 350 companies in Iowa that offer auto insurance. New Jersey topped the list with an average auto insurance premium of nearly 12-hundred dollars. Iowa ranked first in the survey last year with a combined average premium of 557 dollars. Burke-Boston says Iowans should shop around to find the lowest rate available.
