Marcus was T-boned at an intersection on Route 66 near Springfield. The other driver ran a red light. Marcus broke his femur, spent three days in the hospital, and missed ten weeks of work. His medical bills totaled $67,000. The other driver carried Illinois minimum coverage: $25,000 per person. That is all the insurance company will pay. Marcus is on his own for the remaining $42,000.
Marcus's medical bills vs. the at-fault driver's insurance:
| Treatment | Cost |
|---|---|
| Ambulance (12-mile transport) | $2,400 |
| Emergency room | $4,800 |
| Broken femur surgery | $38,000 |
| 3-day hospitalization | $12,600 |
| Physical therapy (16 weeks) | $9,200 |
| Total medical bills | $67,000 |
| Other driver's entire policy limit | $25,000 |
| Gap Marcus must bridge | $42,000 |
Marcus did nothing wrong. He had the green light. But Illinois law only requires the at-fault driver to carry $25,000 in coverage per person - less than the cost of a single surgery.
Why This Matters to You
The $25,000 Problem
Illinois requires every driver to carry at least $25,000 per person / $50,000 per accident in bodily injury liability coverage, plus $20,000 in property damage coverage. This is commonly written as 25/50/20. These numbers are set by the Illinois Vehicle Code (625 ILCS 5/7-601) and have not been updated to reflect the reality of modern medical costs.
$25,000
Per person bodily injury
The most you can collect per person
$50,000
Per accident bodily injury
Split among all injured people
$20,000
Property damage
Vehicle repair or replacement
To put these numbers in context: the average emergency room visit costs approximately $3,300. A single ambulance ride costs $2,000 to $2,500. An inpatient hospitalization averages $57,000. A broken bone requiring surgery commonly exceeds $40,000. The $25,000 per-person minimum was designed for a time when these costs were a fraction of what they are today.
The result is a coverage gap that affects thousands of Illinois accident victims every year. When the at-fault driver carries minimum coverage, their entire insurance policy may not cover even one major medical procedure - leaving the injured person responsible for the rest.
Four States Raised Their Minimums. Illinois Didn't.
In 2025, four states recognized that their insurance minimums were dangerously low and passed legislation to raise them. California doubled its per-person minimum from $15,000 to $30,000. North Carolina and Virginia raised theirs to $50,000 per person. Utah increased from $25,000 to $30,000. Illinois, which shared the same $25,000 minimum as Utah, made no change.
| State | Old Minimum (per person) | New Minimum (2025) | Increase |
|---|---|---|---|
| California | $15,000 | $30,000 | +100% |
| North Carolina | $30,000 | $50,000 | +67% |
| Virginia | $30,000 | $50,000 | +67% |
| Utah | $25,000 | $30,000 | +20% |
| Illinois | $25,000 | $25,000 | 0% |
Before these increases, Illinois was in line with several states. Now it lags behind. A driver who causes a crash in Virginia carries double the per-person coverage of a driver in Illinois. A crash victim in California now has 20% more insurance to claim against than an identical victim in Illinois.
The Per-Accident Limit Matters Too
What $25,000 Actually Buys in 2026
The gap between Illinois's $25,000 minimum and the real cost of accident injuries is not a close call. A single moderate injury can exhaust the entire policy. Here is how quickly $25,000 disappears.
| Medical Service | Average Cost | % of $25K Policy |
|---|---|---|
| Ambulance transport | $2,000 - $2,500 | 8 - 10% |
| Emergency room visit | $3,300 | 13% |
| MRI scan | $2,500 - $4,000 | 10 - 16% |
| Broken bone surgery | $16,000 - $42,000 | 64 - 168% |
| 1-day hospitalization | $4,200 | 17% |
| Spinal fusion surgery | $80,000 - $150,000 | 320 - 600% |
| 12 weeks physical therapy | $6,000 - $9,000 | 24 - 36% |
| Air ambulance / helicopter | $40,000 - $50,000 | 160 - 200% |
A typical moderate car accident injury - an ambulance ride, an ER visit, an MRI, and a course of physical therapy with no surgery - costs roughly $14,000 to $19,000. That alone consumes 56% to 76% of the at-fault driver's entire policy. Add any surgical procedure and the policy is exhausted before the first follow-up appointment.
These Numbers Don't Include Lost Wages or Pain and Suffering
Closing the Gap: 5 Illinois Legal Tools
When the at-fault driver's $25,000 policy does not cover your injuries, Illinois law provides several paths to recover the difference. Most accident victims do not know all of these options exist.
File a UM/UIM Claim on Your Own Policy
Illinois requires every auto insurance policy to include uninsured motorist (UM) bodily injury coverage at minimum levels of $25,000/$50,000. This coverage pays when the at-fault driver has no insurance at all.
Underinsured motorist (UIM) coverage is different - it kicks in when the at-fault driver has some insurance but not enough to cover your injuries. In Illinois, UIM coverage is automatically included in your policy if you purchase UM limits above the state minimum. If you carry only the 25/50 minimum UM, you may not have UIM protection.
Your UIM coverage pays the difference between what the at-fault driver's policy pays and your UIM limit. If you carry $100,000 in UIM and the at-fault driver's $25,000 policy pays out, your UIM coverage can pay up to an additional $75,000.
Sue the At-Fault Driver Personally
Illinois is a fault-based state with no caps on pain and suffering damages in car accident cases. When the at-fault driver's insurance is not enough, you can file a personal injury lawsuit for the full amount of your damages.
If you obtain a judgment that exceeds the insurance policy limit, you can pursue the driver's personal assets. Illinois law allows wage garnishment (up to 15% of gross earnings for non-consumer debts), bank account levies, and property liens. Illinois also allows post-judgment discovery, meaning you can compel the defendant to disclose all assets, income, and property.
The statute of limitations for filing a car accident lawsuit in Illinois is 2 years from the date of the accident. Waiting too long means losing this option permanently.
Use MedPay Coverage
Medical payments coverage (MedPay) is an optional add-on in Illinois that pays your medical bills regardless of who caused the accident. It typically covers $1,000 to $25,000 in medical expenses and pays immediately - no waiting for a settlement or lawsuit.
MedPay is inexpensive to add - often just a few extra dollars per month. It covers you, your passengers, and sometimes your family members. It pays on top of other coverage sources, so it does not reduce your settlement. If you do not currently carry MedPay on your Illinois policy, consider adding it before your next renewal.
Leverage Illinois's Made-Whole Doctrine
When your health insurance pays your accident-related medical bills, the insurer has a subrogation right - meaning they can seek reimbursement from your settlement. However, Illinois follows the made-whole doctrine, which provides critical protection for accident victims.
Under the made-whole doctrine, your health insurer cannot collect subrogation reimbursement until you have been fully compensated for all of your damages. If your total damages are $100,000 and you settle for $50,000, your health insurer cannot claim any of that $50,000 because you have not been "made whole." This means more of your settlement stays in your pocket.
Treat Under a Letter of Protection (LOP)
If you do not have health insurance and the at-fault driver's coverage is too low to pay for treatment, a letter of protection (LOP) allows you to receive medical care now and pay the provider from your settlement later.
Your attorney sends a letter to the medical provider guaranteeing payment from the settlement proceeds. The provider agrees to treat you without requiring payment up front. LOPs are common in Illinois personal injury cases and allow you to get the care you need while your claim is pending. The provider's charges are then subject to the Health Care Services Lien Act protections described below.
Calculate Your Illinois Settlement Value
The 40% Rule: Illinois's Medical Lien Cap
One of the most important protections in Illinois personal injury law is one that most accident victims have never heard of. The Illinois Health Care Services Lien Act (770 ILCS 23/) limits how much hospitals and medical providers can take from your settlement.
How the 40% Cap Works
- 1Total liens cannot exceed 40% of your settlement, judgment, or award. If your settlement is $50,000, the maximum all medical providers combined can claim is $20,000.
- 2No single provider can claim more than 20% if multiple providers have liens. A hospital with a $30,000 lien and a surgeon with a $15,000 lien would each be capped at 20% of your settlement.
- 3You keep at least 60% of your settlement even if your medical bills exceed the total amount. The remaining 60% is yours (minus attorney fees if applicable).
Example: How the 40% cap protects Marcus
| Without Lien Cap | With 770 ILCS 23/ | |
|---|---|---|
| Settlement amount | $50,000 | $50,000 |
| Hospital lien | $38,000 | $10,000 (20%) |
| Surgeon lien | $15,000 | $10,000 (20%) |
| Marcus keeps | -$3,000 | $30,000 |
Without the lien cap, Marcus would owe more than his settlement. With it, he keeps at least $30,000. This is why understanding Illinois lien law is critical when dealing with underinsured at-fault drivers.
Lien Notice Requirements
Why Downstate Illinois Faces Higher Risk
The $25,000 coverage gap hits harder outside the Chicago metro area. Several factors make downstate and rural Illinois accident victims especially vulnerable to underinsured drivers.
More Minimum-Coverage Drivers
Median household incomes in rural Illinois counties are significantly lower than in the Chicago suburbs. Drivers in areas with lower incomes are more likely to carry only the state minimum coverage to keep premiums affordable. The Insurance Research Council estimates that approximately 12-14% of Illinois drivers are uninsured entirely, and many more carry only the minimum.
Longer Ambulance Transport Distances
Rural accidents often require longer ambulance rides to reach a hospital. A 30-mile ambulance transport costs significantly more than a 5-mile urban trip. In severe cases, helicopter transport to a Level I trauma center - which may be 50 or more miles away - costs $40,000 to $50,000 on its own. That single helicopter ride can exceed the at-fault driver's entire policy limit by double.
Higher Speed Limits on Rural Roads
Speed limits on rural Illinois highways are 55-65 mph compared to 25-45 mph in urban areas. Higher speed crashes produce more severe injuries - and more expensive medical bills. A rear-end collision at 60 mph on I-55 near Bloomington causes far more damage than the same collision at 30 mph in a Peoria neighborhood.
Fewer Trauma Centers
Most Level I and Level II trauma centers in Illinois are concentrated in the Chicago area and a handful of downstate cities. Accident victims in rural areas may need to be transferred to a major medical center, adding transfer costs and delays in treatment. These transfers often require a second ambulance ride or helicopter transport.
Winter Driving Conditions
Illinois winters bring black ice, heavy snowfall, and reduced visibility across the state. Winter driving conditions contribute to a seasonal spike in accidents, particularly on interstate highways like I-55, I-57, and I-72. Multi-vehicle pileups during winter storms can involve dozens of vehicles and spread the $50,000 per-accident coverage among many injured people.
Farm Equipment Is a Factor Too
5 Steps to Protect Yourself Before an Accident
You cannot control whether the driver who hits you carries minimum coverage. But you can take steps now to protect yourself from the $25,000 coverage gap.
Check your UM/UIM limits right now
Pull up your auto insurance declarations page and look for "Uninsured Motorist" and "Underinsured Motorist" lines. Most Illinois drivers do not know their UIM limits - or whether they even have UIM coverage. If your UM limits are at the $25,000/$50,000 minimum, you likely do not have UIM protection. Call your insurer and ask specifically about your UIM coverage.
Increase your UM/UIM coverage to at least 100/300
Raising your UM/UIM limits from 25/50 to 100/300 typically costs $30 to $60 more per month. This gives you $100,000 per person in underinsured motorist protection. If a minimally insured driver causes $80,000 in damages, your UIM pays the $55,000 gap instead of you paying it out of pocket.
Add MedPay coverage
MedPay is the most underused coverage in Illinois. For a few extra dollars per month, you get $5,000 to $25,000 in immediate medical bill coverage that pays regardless of fault. MedPay pays on top of everything else - it does not reduce your settlement or your UM/UIM payout. It covers ambulance rides, ER visits, and initial treatment while you wait for the at-fault driver's insurance to respond.
Document everything immediately after an accident
When the at-fault driver has minimum coverage, maximizing every dollar matters. Photograph the scene, the vehicles, your injuries, and any visible damage. Get the police report number. Save all medical bills, receipts, and records. Document lost wages with pay stubs and employer letters. The stronger your documentation, the stronger your claim against every available coverage source.
Do not accept the policy limit without exploring all options
When the at-fault driver's insurer offers you their full $25,000 policy limit, it can feel like the best you can do. Before accepting, explore whether you have UIM coverage, whether MedPay applies, whether a personal lawsuit against the driver is viable, and whether the made-whole doctrine protects your settlement from subrogation. Many Illinois accident victims leave tens of thousands of dollars on the table because they accept the policy limit without knowing their other options.
Frequently Asked Questions
What is the minimum car insurance required in Illinois in 2026?
Illinois requires minimum liability coverage of $25,000 per person for bodily injury, $50,000 per accident for bodily injury, and $20,000 for property damage (25/50/20), as set by the Illinois Vehicle Code (625 ILCS 5/7-601). Illinois also requires uninsured motorist bodily injury (UMBI) coverage at the same 25/50 minimum levels. These amounts have not changed in 2026, making Illinois one of the states with the lowest per-person bodily injury minimums in the country.
What happens if the other driver's insurance doesn't cover my medical bills in Illinois?
If the at-fault driver's policy limit is less than your medical bills, you have several options under Illinois law. You can file an underinsured motorist (UIM) claim on your own policy if you carry UIM coverage. You can use MedPay coverage if you have it. You can file a personal injury lawsuit against the at-fault driver for the full amount of your damages - Illinois has no damage caps in car accident cases and allows wage garnishment and asset recovery if the driver has assets beyond their insurance. Your health insurance may also cover treatment, subject to subrogation protections under the made-whole doctrine.
Does Illinois require uninsured motorist coverage?
Yes. Illinois mandates uninsured motorist bodily injury (UMBI) coverage at minimum levels of $25,000 per person and $50,000 per accident. This coverage protects you when the at-fault driver has no insurance. Underinsured motorist (UIM) coverage - which applies when the at-fault driver has insufficient insurance - is automatically included if you purchase UM limits above the state minimum. Illinois insurers are required to offer UIM coverage in all auto insurance policies.
Can I sue the other driver personally if their insurance isn't enough?
Yes. Illinois is a fault-based state, which means you can file a personal injury lawsuit against the at-fault driver for the full amount of your damages, even if it exceeds their insurance policy limit. Illinois has no caps on pain and suffering damages in car accident cases. If you obtain a judgment exceeding the policy limit, you can pursue the driver's personal assets through wage garnishment (up to 15% of gross earnings), bank levies, and property liens. The statute of limitations is 2 years from the date of the accident.
What is the Illinois Health Care Services Lien Act?
The Illinois Health Care Services Lien Act (770 ILCS 23/) allows hospitals and medical providers to place liens on your car accident settlement to recover the cost of treatment. The law caps total medical liens at 40% of your settlement, judgment, or award. If multiple providers have liens, no single provider can claim more than 20% of the settlement. This means that regardless of how high your medical bills are, you are guaranteed to keep at least 60% of your settlement.
How much car insurance should I actually carry in Illinois?
Financial advisors and personal injury attorneys generally recommend carrying at least 100/300/100 coverage ($100,000 per person, $300,000 per accident for bodily injury, $100,000 for property damage) with matching UM/UIM limits. Adding $10,000 to $25,000 in MedPay coverage provides immediate no-fault medical bill coverage. The cost difference between minimum and recommended coverage is typically $30 to $60 per month. Given that the average car accident with injuries costs $15,000 to $57,000 in medical bills alone, the extra coverage pays for itself the moment you need it.
