Insurance Policy Limits in Illinois: How a $25,000 Cap Changes Everything About Your Case

Here’s a scenario that plays out in our office more often than it should. A client comes in after a serious car accident. They have documented injuries—a herniated disc, a fracture, months of physical therapy. Their medical bills are already past $30,000. And then we pull the at-fault driver’s insurance declaration page and see the number: $25,000. That’s the per-person liability limit. That’s all the money that exists on that side of the case, no matter how badly our client was hurt.

Illinois requires drivers to carry only $25,000 per person in bodily injury liability coverage. That amount hasn’t kept pace with the cost of medical care, and it doesn’t go far when someone is seriously hurt. And for anyone with injuries that exceed that threshold—which doesn’t take much—the policy limit becomes the defining constraint of the entire case.

What Policy Limits Mean in Practice

A liability insurance policy limit is the maximum amount the at-fault driver’s insurer will pay for your injuries. If the at-fault driver carries $25,000 in coverage and your damages are $80,000, you don’t get $80,000 from their policy. You get $25,000. The insurer has no obligation to pay more than the policy limit, regardless of how clear the liability is or how serious the injuries are.

This is the fundamental reality that most people don’t understand until they’re living it. The at-fault driver’s insurance doesn’t scale to your injuries. It’s a fixed cap, chosen by the at-fault driver (or their insurance agent) when they bought the policy—usually long before the accident happened and without any thought about the people they might one day hurt.

Under Illinois law (625 ILCS 5/7-317), the minimum required liability coverage is $25,000 per person and $50,000 per accident. A significant number of Illinois drivers carry exactly the minimum. Some carry no insurance at all, despite the legal requirement. When you’re the person on the other side of that collision, the policy limit—not the severity of your injuries—becomes the ceiling.

When the At-Fault Driver’s Policy Isn’t Enough

In cases where the injuries exceed the at-fault driver’s policy limits, we look at every available source of coverage. This is where a personal injury attorney earns their fee—not just by negotiating one claim, but by identifying and pursuing every applicable policy.

Underinsured motorist (UIM) coverage. Under Illinois law (215 ILCS 5/143a), every auto liability policy issued in this state must include UM/UIM coverage. And here’s the important part: if you didn’t specifically reject UIM coverage in writing when you bought the policy, you’re presumed to have it at the same level as your liability limits. UIM kicks in when the at-fault driver’s insurance isn’t enough to cover your damages. It fills the gap between what you collected from the at-fault driver and the full value of your injuries, up to your own UIM limit. The UIM insurer subtracts (or “sets off”) whatever you already received from the at-fault driver. So if you have $100,000 in UIM coverage and already collected $25,000 from the at-fault driver’s policy, your UIM carrier can pay up to $75,000 on top of that. This is why we consistently advise clients to carry UIM limits that match their liability limits—it’s the single most important protection you can buy. Our guide to filing a UM/UIM claim in Illinois walks through the process step by step.

Umbrella policies. Some at-fault drivers carry umbrella or excess liability policies that sit on top of their auto coverage. Not every driver carries one, but when they exist, they can provide significant additional coverage above the auto policy limits. We always investigate whether the at-fault driver has umbrella coverage, because it’s not always disclosed upfront.

Multiple vehicles, multiple policies. In Illinois, if the at-fault driver had multiple vehicles on their policy, there may be opportunities to stack UM/UIM coverage across vehicles to increase the available limits. The rules on stacking are complex—some policies explicitly anti-stack, and the case law is nuanced—but it’s always worth investigating.

Other liable parties. Was the at-fault driver working at the time of the accident? Their employer may be vicariously liable and carry a separate commercial auto policy with higher limits. Was the driver operating a borrowed vehicle? The vehicle owner’s policy may also apply. Were road conditions a contributing factor? A government entity’s negligent road maintenance can open a separate claim with its own coverage.

What Happens When You Tender the Policy Limits

When the at-fault driver’s policy limit is clearly insufficient, the standard approach is to “tender” the policy—demand the full limit and get it paid out, then move on to the next source of recovery. But even this step has important procedural requirements in Illinois.

Before accepting the at-fault driver’s policy limits, you must notify your own UIM carrier and give them the opportunity to consent to the settlement. The UIM carrier has what’s called “subrogation rights”—the legal right to go after the at-fault driver to recover what they paid you. If you settle with the at-fault driver without your UIM carrier’s permission, you destroy their ability to do that. Under Illinois law, if you accept the liability policy limits without your UIM carrier’s written consent, you may waive your right to pursue the UIM claim entirely. Best practice—and the procedure we follow in every case—is to send written notice to the UIM carrier and obtain written consent before accepting any settlement from the at-fault driver’s insurer. This is one of the most common and most devastating procedural mistakes in personal injury law, and it’s entirely avoidable with proper legal counsel.

Once the liability policy is tendered and the UIM carrier has consented, you file your UIM claim against your own insurer. The UIM claim is essentially a new negotiation—with a new demand, a new adjuster, and sometimes a different set of challenges. Your own insurer is now on the other side of the table, and they don’t always make it easy. As we discuss in our post on when your own insurance company fights your UM/UIM claim, the dynamic changes when the insurer who sold you the policy is the one trying to minimize your payout.

How Policy Limits Affect Case Strategy from Day One

An experienced personal injury attorney identifies the available insurance coverage early—ideally within the first few weeks of taking the case. That means pulling the at-fault driver’s insurance declaration page, reviewing our client’s own auto policy for UM/UIM and MedPay coverage, and investigating whether any other parties or policies might apply.

Knowing the insurance architecture shapes every decision that follows. If the available coverage is limited, we may prioritize getting the client into treatment through their health insurance (which has negotiated lower rates) rather than leaving medical providers to bill at full chargemaster rates—because in a limited-coverage case, every dollar of medical bills matters when we’re negotiating liens against a fixed recovery.

If the coverage is more robust—say, the at-fault driver has $250,000 in limits, plus our client has $100,000 in UIM—the strategy shifts toward building the maximum case value through thorough documentation, specialist referrals, and a comprehensive demand package. The available coverage creates the playing field; the legal strategy determines how much of that field we can capture.

The Bottom Line: Your Insurance Matters as Much as Theirs

The at-fault driver’s insurance is the most visible source of recovery, but it’s often not the most important one. In a state where the minimum is $25,000 and serious injuries routinely exceed that amount, your own UM/UIM coverage is frequently the difference between an inadequate recovery and a fair one.

If you’re reading this before an accident: check your policy. Increase your UM/UIM limits to at least $100,000—ideally to match your liability limits. The cost difference is usually modest, and the protection is enormous.

If you’re reading this after an accident and you’re worried that the at-fault driver doesn’t have enough insurance: talk to an attorney before you accept any settlement. There may be sources of recovery you haven’t considered. The car accident attorneys at Parker & Parker evaluate every available policy in every case—because leaving coverage on the table is leaving money on the table.

Frequently Asked Questions

What are the minimum car insurance requirements in Illinois?

Illinois requires drivers to carry at least $25,000 per person and $50,000 per accident in bodily injury liability coverage, plus $20,000 in property damage coverage (625 ILCS 5/7-317). Uninsured and underinsured motorist coverage (UM/UIM)—which protects you when the other driver has no insurance or not enough—is not technically required but is strongly recommended. These minimums have not kept pace with the cost of medical care, which means a driver carrying minimum coverage may not have nearly enough to compensate someone they seriously injure.

What happens if the at-fault driver only has $25,000 in insurance and my injuries are worse than that?

You can recover up to the $25,000 limit from their policy, and then pursue additional recovery through your own underinsured motorist (UIM) coverage if you have it. Your attorney may also investigate whether the at-fault driver has umbrella coverage, whether other parties share liability, or whether other insurance policies apply. Without UIM coverage on your own policy, the $25,000 may be the most you can recover from insurance—regardless of how serious your injuries are.

Do I need to notify my own insurance company before accepting the at-fault driver’s policy limits?

Yes, and this is critical. Under Illinois law, you must notify your UIM carrier and obtain their consent before accepting the at-fault driver’s liability limits. If you accept without consent, you may waive your right to file a UIM claim entirely. This is one of the most important procedural steps in a limited-coverage case, and it’s a primary reason to have an attorney involved before any settlement is accepted.

How much UM/UIM coverage should I carry?

We recommend carrying UM/UIM limits that match your liability limits—at minimum $100,000 per person. The cost of increasing UM/UIM coverage is typically modest compared to the protection it provides. In our experience, UM/UIM claims are some of the most valuable recoveries our clients make, because the coverage exists specifically for the situation where the at-fault driver’s insurance is inadequate.

If you were injured by a driver without adequate insurance, the experienced Peoria personal injury lawyers at Parker & Parker can help you explore all available options for recovery.
