A Financial Responsibility Insurance Certificate (SR-22) is proof or verification the holder is maintaining vehicle liability insurance in the required amounts. It is not a type of insurance—it is a form filed with the state’s department of public safety (DPS), department of transportation (DOT), or department of motor vehicles (DMV) and may also be referred to as an SR-22 Bond or SR-22 Form.

An SR-22 can be issued by most insurance providers, who will notify the state’s department of public safety or department of motor vehicles when an SR-22 is cancelled, terminated, or lapses.

The state will often require a driver whose license has been suspended following an arrest for DUI/DWI to provide an SR-22 in order to get their occupational or restricted license or to have their driver’s license reinstated.

In Idaho, an SR-22 is a certificate of financial responsibility required by the state to verify that an individual is maintaining the minimum vehicle liability insurance required by law. This certificate is not an insurance policy but a form that the insurance company files with Idaho's transportation department. It is typically required for drivers who have had their licenses suspended or revoked due to serious traffic violations such as DUI/DWI. The insurance provider is responsible for notifying the Idaho Department of Motor Vehicles (DMV) if the SR-22 is canceled, terminated, or lapses. Drivers may need to maintain an SR-22 for a set period, often three years, to have their driving privileges reinstated or to obtain a restricted or occupational license.
