The most expensive state is Michigan with a $2,738 average annual premium, more than double the national average of $1,325. The Michigan rate is about $450 more than second-place Montana and $800 more than third-place New Jersey, reported


On the other hand, Maine was the least expensive at $808, almost $100 less than second-place Ohio, while Wisconsin cost a little over $100 more than Maine.
