In South Dakota, an SR‑22 (Certificate of Financial Responsibility) is required for drivers who have had their license revoked or suspended because of serious offenses such as a conviction for no insurance, vehicular homicide, DUI, or a second reckless‑driving offense within a year. The state mandates that these operators provide proof of ongoing liability coverage by obtaining an SR‑22 filing from their auto‑insurance company, which the insurer submits electronically to the Department of Public Safety.
The SR‑22 must remain on file for three years from the date of conviction. To reinstate a suspended or revoked license, the driver must pay a reinstatement fee in addition to the standard application fee, and may need to complete vision and knowledge tests if the license was revoked. Failure to maintain the SR‑22 results in suspension of vehicle registration, license plates, and the driver’s license.
