In the United States, an SR-22 (sometimes referred to as a certificate of insurance[a] or a financial responsibility filing)[1][2] is a vehicle liability insurance document required by most state departments of motor vehicles (DMV) offices[b] for "high-risk" insurance policies.
[4] A DMV may require an SR-22 from a driver to reinstate his or her driving privileges following an uninsured car accident or conviction of another traffic-related offense, such as a DUI.
[4][7] Some states accept an SR-22 as an alternative to a deposit in cash or security as proof of financial responsibility.
In Arizona, for instance, a driver seeking reinstatement under specific circumstances may submit an SR-22 in lieu of depositing $40,000 in cash or certificates of deposit.
[8] The same applies in Washington State where you may submit an SR-22 instead of a liability bond of at least $60,000 from any surety or bonding company that is licensed to operate in Washington.
