Your own uninsured motorist (UM) coverage typically pays medical bills, lost wages, and other injury costs when an at-fault driver carries no insurance in Illinois. If you lack UM protection, you may need to file through MedPay, health insurance, or pursue the uninsured driver directly; however, collecting from someone without coverage often proves difficult.
Crashes with uninsured motorists happen across Southern Illinois rural highways and interstates, along Route 13 from Harrisburg to Carbondale and Murphysboro, from I-57 and I-24 near Marion, all the way down to Cairo and Metropolis.
When police reports confirm the other driver holds no liability policy, Dihle Law Firm helps injured drivers in Jackson, Williamson, Franklin, and surrounding counties secure the UM benefits, MedPay coverage, and medical liens needed to cover treatment costs and lost income while you recover. Our proven results demonstrate our commitment to clients.
Key Takeaways for Uninsured Driver Accidents in Southern Illinois
- UM coverage on your policy pays injury costs when the at-fault driver lacks insurance; UIM coverage applies when their limits fall short
- Illinois requires UM/UIM offers at liability limits unless you reject in writing
- Hit-and-run crashes qualify as UM claims if you report promptly and document the incident
How Uninsured Motorist (UM) Coverage Works in Illinois
Illinois law mandates that insurers offer UM and underinsured motorist (UIM) coverage at the same limits as your bodily injury liability policy. You must reject these protections in writing or they automatically attach to your auto policy.
UM coverage pays when the at-fault driver carries zero insurance. UIM coverage activates when the negligent driver's liability limits are too low to cover your injuries.
Both coverages reimburse medical expenses, rehabilitation costs, lost income, and pain and suffering damages up to your policy limits. You file the claim with your own insurer, not the insurer of the at-fault party. Your insurer investigates liability, reviews medical records, and determines payout just as if you were pursuing a third-party claim.
Why UM Claims Move Faster Than Lawsuits
UM and UIM claims proceed more efficiently than filing suit against an uninsured defendant because you work directly with a company that already holds your policy file. Your insurer has immediate access to coverage terms, payment procedures, and claims adjusters familiar with your account. However, insurers sometimes dispute fault or injury severity, so thorough documentation remains critical.
What UM and UIM Coverage Pays For
UM and UIM benefits address the full scope of collision-related damages when the at-fault driver lacks adequate insurance. The coverage typically includes:
- Emergency room treatment, surgery, and hospital stays
- Diagnostic imaging, specialist consultations, and rehabilitation therapy
- Prescription medications and durable medical equipment
- Lost wages during recovery and diminished future earning capacity
- Pain-and-suffering damages proportionate to injury severity
Your policy caps limit the total payout, so selecting higher UM/UIM coverage at policy inception provides stronger financial protection after serious crashes.
What Happens When You Have No UM Coverage
Drivers who rejected UM protection in writing face limited recovery options after an uninsured motorist crash. You may file through MedPay on your own policy if you purchased it. MedPay reimburses hospital bills, ambulance fees, and co-pays regardless of fault. The amount will depend on the policy you selected.

When MedPay coverage is exhausted or unavailable, your personal health insurance becomes the next layer of protection. Health plans cover treatment but impose subrogation rights, meaning they may demand repayment if you later recover compensation from the at-fault driver or any other liable party. Federal ERISA plans and state-regulated health insurers both enforce these liens, reducing your net recovery.
You retain the right to sue the uninsured driver personally, but judgments can prove difficult to collect when the defendant lacks assets or income. Many uninsured motorists carry no recoverable funds, making UM coverage the most reliable payment source after a Southern Illinois uninsured motorist crash.
Underinsured Motorist (UIM) Coverage Explained
UIM coverage pays the gap when the at-fault driver's liability policy falls short of your total damages. Illinois law treats UM and UIM as paired protections, each available at the limits you select.
UIM claims require you to settle or exhaust the at-fault driver's liability coverage first. You then present your full damage calculation to your own carrier, supported by medical records, wage documentation, and expert reports when necessary. Insurers sometimes dispute whether injuries exceed the at-fault driver's limits, so detailed treatment notes and life-care plans strengthen your position.
Filing a UM Claim After a Hit-and-Run Crash
Hit-and-run accidents qualify as UM claims under Illinois law when the at-fault driver flees without providing insurance information. You must report the crash to law enforcement promptly and cooperate fully with the police investigation.

Illinois Vehicle Code sections 625 ILCS 5/11-401, 625 ILCS 5/11-404, and 625 ILCS 5/11-407 govern the obligations to report hit-and-run accidents. Meeting these reporting obligations helps preserve UM benefits for phantom-vehicle claims.
Police reports documenting hit-and-run incidents provide essential proof for UM claims. Officers record vehicle descriptions, direction of travel, and physical evidence, such as paint transfers or tire marks. These details help insurers verify that a phantom driver was involved in the crash, rather than a single-vehicle incident.
Your insurer investigates whether independent evidence corroborates the collision. Dashboard camera footage, nearby security video, witness statements, and roadway debris all support your account. Rural highways in Jackson, Williamson, and Franklin Counties offer fewer cameras than urban intersections, so witness contact information becomes vital at the scene.
Evidence That Builds Strong UM and UIM Claims
Gathering solid evidence early strengthens your position when negotiating with your own insurer or pursuing UIM recovery after exhausting the at-fault driver's policy.
- Police crash report showing the other driver's lack of insurance or policy limits
- Photos of vehicle damage from multiple angles, plus roadway conditions and traffic control devices
- Medical records, including ER notes, diagnostic imaging, treatment plans, and therapy progress notes
- Wage documentation such as pay stubs, tax returns, employer letters, or profit-and-loss statements for self-employed drivers
- Witness statements with full contact information, recorded soon after the crash
- Insurance declarations page confirming your UM/UIM policy limits and rejection forms if applicable
Organizing these documents before filing helps your insurer process the claim faster and reduces disputes over coverage or injury severity.
FAQ for Uninsured Driver Accidents in Southern Illinois
Does My UM Coverage Pay If I'm Partially at Fault?
Illinois comparative negligence rules reduce UM payments by your percentage of fault. You remain eligible for benefits as long as your fault stays below 51 percent, but any liability assigned to you lowers the payout.
Can I Stack UM Coverage From Multiple Vehicles?
Illinois prohibits UM stacking unless your policy explicitly allows it. Most insurers offer only the highest single-vehicle UM limit, even when household members own multiple cars. Review your policy declarations or call your agent to confirm whether stacking applies.
How Long Do I Have to File a UM Claim in Illinois?
UM claims follow the same statute of limitations as third-party personal injury cases, generally two years from the date of the collision under Illinois law. Waiting too long bars recovery, so early documentation and legal consultation preserve your rights.
