An SR-22 is a form that is filed with your state to show that you are meeting your states minimum auto liability insurance requirements. It is not an insurance policy, but rather a certificate of financial responsibility required for some drivers by their state or court order. An SR-22 is added to a personal automobile liability insurance policy as an add-on or filing). It is required by most state departments of motor vehicles (DMV) offices for "high-risk" insurance policies). Not all insurance carriers offer SR-22 filings in all territories). An SR-22 may be required for three years for conviction of driving without insurance or driving with a suspended license and up to five years for a DUI). If an SR-22 should expire or be canceled, the insurance company is required to issue an SR-26 form, which certifies the cancellation of the policy). Some states accept an SR-22 as an alternative to a deposit in cash or security as proof of financial responsibility).
