An SR-22 is a certification of financial responsibility, not an actual insurance policy. In Idaho, you or your insurer file this form after certain moving violations, such as a DUI. While the SR-22 itself doesn't change your rates, the infractions necessitating it can lead to higher premiums for minimum coverage auto insurance.
For those needing minimum coverage SR-22 car insurance in Idaho, the two most affordable companies are State Farm, with an average annual rate of $233, and American National P&C, with an average annual rate of $305. For non-owner SR-22 car insurance, the two cheapest liability-coverage options are Auto-Owners, with an average annual premium of $146, and State Farm, with an average annual premium of $236.
