SR-22 insurance, or an SR-22, is a certification issued by your car insurance company showing proof that you are carrying the minimum liability coverage required by your state. If you have been involved in an accident and were not carrying minimum car insurance, most state DMVs will require you to hold an SR-22. SR-22s can also be required for other types of traffic offenses.
While each state has its own requirements, examples of circumstances that frequently require an SR-22 include the following:
DUI or DWI or any serious moving violation
At-fault accidents while driving without insurance
Repeat traffic offenses or getting too many tickets in a short time period
To reinstate a suspended or revoked license
