SR-22 is not insurance itself. It's a certificate of financial responsibility your insurer files with the state that proves you have the required insurance coverage. Drivers typically need an SR-22 if they’re caught driving without insurance or a license or if they commit a DUI (driving under the influence) or other serious traffic violations.
