FR-44 is an insurance document showing proof of financial responsibility and verifies you have auto liability coverage. This type of document, which is not car insurance, is required after certain driving incidents like a DUI or driving with a suspended license.
You are required to carry FR-44 Insurance for a designated period of time, typically 3 consecutive years, depending on the severity of your incident. If you break your coverage, it will be reported to the state and result in your license being suspended.
