In Illinois, UM coverage is tied to your policy language and the facts of the crash—not just what you believe happened. In practical terms, UM coverage often matters when:
- The other driver is uninsured or can’t be traced.
- The other driver’s insurance doesn’t satisfy the required coverage terms.
- Your insurer disputes whether your losses fall within UM provisions.
Because the UM claim is filed through your policy, the insurer may focus on two questions early:
- Did the crash happen the way you say it did?
- Do your medical records support that the injuries were caused by the crash?
