A SR 22 is a financial responsibility filing with the state of Illinois that verifies that you have an auto or non-owner auto insurance policy with at least the state minimum liability limits.
Once you are required by the State to have an SR 22 financial responsibility filing, the documentation is filed with the state by the insurance company on your behalf. If your policy cancels due to nonpayment of premium, or by your request notification will be sent to the state by the insurance company stating that your insurance policy has been canceled, which may result in a drivers license suspension.
Although requirements may vary, most SR 22's are required for the length of three years. You can check with the State of Illinois Department Of Mandatory Insurance at 217-782-3720 option 7 to verify how long you will need the SR 22
Once in SR 22 is purchased will notify the state electronically, which the state will receive the following business day. However it may take the state up to three business days after receiving the SR 22 to activate it.
