Trucking insurers have a financial incentive to stall. Every month a case sits unresolved is a month the carrier keeps its money working for it, not you.
Illinois law pushes back on that. Prejudgment interest in a truck accident case can add real money, sometimes tens of thousands of dollars, to a final recovery. And the clock on that interest starts the day the lawsuit is filed, not the day of the crash.
This article shares general legal information. For advice specific to your situation, talk with a licensed Illinois attorney.
How Prejudgment Interest Works Under Illinois Law
Under 735 ILCS 5/2-1303(c), prejudgment interest builds at a rate of 6% per year on damages in personal injury and wrongful death cases. That interest starts running on the day the complaint is filed. Not the day of the wreck, and not the day a jury reaches a verdict.
The statute caps that accrual at five years. Run the math and the ceiling comes out to 30% of the eventual judgment, in simple interest, no compounding.
Here’s what that looks like with round numbers. Say a truck accident victim files suit in January 2024, and the case goes to trial two years later, in January 2026. If the jury awards $500,000 in damages, prejudgment interest at 6% annually adds $60,000 to that (two years times $500,000 times 0.06). The total judgment comes to $560,000.
That $60,000 is not a bonus. It’s the price the insurer pays for taking two years to resolve a case it could have settled sooner.
The Settlement Offer Rule That Changes the Negotiation
The most tactically significant feature of 735 ILCS 5/2-1303(c) is how it treats settlement offers that fall short of the final verdict. If the defendant makes an offer and the plaintiff ends up with a judgment that beats it, interest keeps accruing from the original filing date. Not from the date of the offer.
That’s a real shift in who holds the edge in negotiations. Under older frameworks, a defendant could float a token early offer, argue that it stopped future interest from building, and push the risk of accumulating interest onto the plaintiff. Illinois closed that door.
Under the current statute, a low-ball offer does nothing to the interest clock. The insurer has to offer an amount that meets or beats the eventual judgment, or the full accrual runs from filing regardless. A carrier that offers $200,000 early and then watches a jury award $600,000 is not just short on the verdict. It owes interest on the full $600,000, calculated from the day the case was filed.

Why This Rule Matters More in Trucking Cases
Trucking cases feel the effect of delay tactics more than most. Commercial trucking insurers typically carry high policy limits. Federal minimums for freight carriers sit at $750,000, and many policies run to $1 million or higher. Bigger numbers give insurers more reason to resist an early settlement, and more financial room to fund a long fight. Cases involving catastrophic injury or wrongful death often carry years of medical documentation and expert witness preparation, which stretches the timeline even further.
The prejudgment interest statute changes that math. A $1 million case held for three years accrues $180,000 in statutory interest at 6%. That’s money a carrier cannot recover, cannot invest, and cannot write off against its litigation budget.
We’ve used the filing-date accrual rule directly in settlement demand letters, laying out for a carrier exactly what further delay costs in dollar terms.
Constitutionality and Current Status of the Statute
The statute has drawn constitutional challenges from defendants and insurers since it took effect, arguing that the 6% rate and the five-year cap overstep what the legislature can impose. It remains active law today, and it applies to personal injury and wrongful death cases filed in Illinois courts. An attorney can walk you through where a specific challenge currently stands if it matters to your case.
Retroactivity was an early flashpoint too, whether interest could apply to cases filed before the statute’s effective date. For anything filed today, that question is moot.
For a case filed today, none of that ambiguity applies. Interest accrues at 6% annually from the filing date, stops after five years, and is not tolled by an inadequate settlement offer.
What This Means If You Are Negotiating With a Trucking Insurer
If you’ve already filed suit, every month that passes without a fair settlement adds to what the insurer owes. That advantage is yours, but only once a complaint is on file and the interest clock is running.
Cases still sitting in pre-litigation demand do not accrue statutory interest. That’s one reason filing suit promptly in a serious trucking case can pay off beyond simply protecting the statute of limitations deadline.
No attorney can promise that prejudgment interest will be awarded in any specific case. Liability still has to be established, and damages still have to be proven at trial or reflected in a settlement.
But for someone whose case is headed toward litigation against a well-funded trucking insurer, that 6% accrual from the filing date is not theoretical. It’s a real, calculable part of what the claim is worth.
