Key Takeaways
- Illinois drivers no longer file their own crash report. That requirement was repealed on 20 August 2021.
- The $1,500 figure still matters, but for a different duty: notifying police immediately, under 625 ILCS 5/11-407.
- It drops to $500 where a vehicle that should carry liability insurance does not.
- The 10-day deadline is the officer’s, not yours. It is the period for police to forward their report to the state.
- In a truck crash the threshold is almost always irrelevant. A loaded tractor-trailer clears $1,500 on contact.
- The deadline that does matter is the carrier’s evidence, including an accident register the carrier keeps for only three years.
The short answer
The $1,500 figure is real and current, but it does not mean what most articles say it means. It is the point at which you must notify police, not the point at which you must file a report yourself.
Illinois used to require every driver in a qualifying crash to file a written report. 625 ILCS 5/11-406 was repealed by Public Act 102-560, effective 20 August 2021. If you are reading a checklist that tells you to file a driver’s crash report within ten days, it is describing a duty that no longer exists.
What the law requires now
The surviving obligation is in 625 ILCS 5/11-407(a). Where no police officer is present, the driver must give notice of the crash “by the fastest available means of communication” to the local police department, the county sheriff or the Illinois State Police. Notice is required if the crash:
| Trigger | Detail |
|---|---|
| Injury or death | Any personal injury to or death of any person |
| Property damage over $1,500 | Damage to the property of any person, including the driver |
| Over $500 if uninsured | Where a vehicle involved is subject to Section 7-601 but is not covered by a liability insurance policy |
| School bus involved | Any property damage, personal injury or death, however caused |
| Within 50 feet of a school bus | Injury or death to someone boarding or just off the bus |
Two things follow. The duty is immediate, not a countdown. And it is discharged by calling the police, which in practice happens at the scene of any truck crash anyway.
Where the ten days actually comes from
This is the detail that trips people up, because the ten-day period is real. It just is not yours.
Under 625 ILCS 5/11-408, a law enforcement officer who investigates a crash for which a report is required, or who prepares a written report, must forward that report to the Administrator “within 10 days after investigation of the motor vehicle crash.” That is a police obligation and a police deadline. Nothing in it asks anything of you.
Worth knowing about the resulting report: under 625 ILCS 5/11-412, required written crash reports are confidential and are for the use of the Department and the Secretary of State, subject to the exceptions the section sets out.
Why the threshold barely matters in a truck case
A federal tractor-trailer combination can run to 80,000 pounds. Any contact serious enough to be worth reading about has already cleared $1,500 in damage, so the question of whether the threshold is met is essentially never the live issue in a commercial vehicle case.
Treating $1,500 as a decision point is the real error. It is a police-notification trigger, not a measure of whether a claim is worth pursuing, and it says nothing at all about injuries, which are what actually determine the value of a truck case.
The same reasoning applies to the repair estimate itself. Commercial collisions routinely produce frame and mechanical damage that a first estimate misses, so a figure near the threshold usually understates what happened rather than describing it. But the reason to look harder is the injury picture, not the paperwork consequence, because there is no longer a form whose availability turns on the number.
What the repeal changed, and what it did not
Because the old rule is still repeated widely, it is worth being precise about the boundary.
| Duty | Status |
|---|---|
| Driver files a written crash report | Repealed, 20 August 2021 |
| Driver gives immediate notice to police | Current, 625 ILCS 5/11-407 |
| Driver stops at the scene, gives information and renders aid | Current, 625 ILCS 5/11-401 and 11-403 |
| Police forward their report within 10 days | Current, 625 ILCS 5/11-408, and not a driver duty |
The scene obligations are the ones with teeth. Under 625 ILCS 5/11-401 a driver involved in a crash resulting in injury or death must stop immediately and remain until the requirements of 11-403 are met, and 11-403 requires giving name, address, registration and owner details, exhibiting a license on request where available, and rendering reasonable assistance to anyone injured, including arranging transport for treatment where it is apparently necessary or requested.
The deadlines that do matter
Meanwhile, evidence that decides truck cases is disappearing on its own schedule.
- The carrier’s accident register: three years. Under 49 CFR 390.15(b) a motor carrier must maintain an accident register for three years after each accident, recording the date, location, driver name, number of injuries, number of fatalities and whether hazardous materials were released.
- Electronic logging and engine data, which is retained on the carrier’s own retention cycles rather than yours.
- Dashcam and facility video, commonly overwritten in one to two weeks.
- The vehicles themselves, before repair or salvage.
A preservation letter sent early is worth more than any reporting form. We go through the sequence in our post on when to file after a truck collision.
Three investigations, only one of which is yours
After a serious truck crash, several records are being created at once, by parties with different interests.
- The police investigation. Produces the crash report forwarded under 11-408. Useful, but written quickly and from limited information, and an officer’s conclusion about fault does not bind anyone in a civil case.
- The carrier’s own investigation. Often begins within hours. Trucking companies and their insurers dispatch people to serious crashes precisely because the evidence is perishable, which means the other side may be gathering it while you are still in hospital.
- Your investigation. The one that starts last, unless somebody sends a preservation letter early.
That asymmetry, rather than any reporting threshold, is the practical reason to get advice quickly after a commercial vehicle collision. The carrier is not waiting for a form.
Federal rules are Illinois rules
The reason a truck case reaches evidence a car case never touches is that Illinois has adopted the federal safety regime as state law. 625 ILCS 5/18b-105(b) adopts by reference, “as though they were set out in full,” a list of Title 49 parts including:
- Part 382, controlled substances and alcohol testing
- Part 391, qualifications of drivers
- Part 392, driving of motor vehicles
- Part 393, parts and accessories necessary for safe operation
- Part 395, hours of service of drivers
- Part 396, inspection, repair and maintenance
Each of those generates records: qualification files, testing results, logs, inspection and repair history. That is the material a truck case is actually built from, and it is why who ultimately pays is often a different question from who was driving.
What to do at the scene and after
- Call the police. This discharges the 11-407 duty and produces the report that follows.
- Photograph everything, including the tractor and trailer markings, the USDOT number, and the placards.
- Get medical attention, because injuries rather than repair estimates determine what a truck claim is worth.
- Do not give a recorded statement to the carrier’s insurer before you understand what is in their file.
- Get a preservation letter out, which is the only step on this list with a genuine clock on it.
Frequently Asked Questions
Do I still have to file a crash report in Illinois?
No. The requirement for a driver to file a written crash report came from 625 ILCS 5/11-406, which was repealed by Public Act 102-560 effective 20 August 2021. What survives is a duty to notify police immediately in the situations set out in 625 ILCS 5/11-407, which is discharged by calling them.
What does the Illinois $1,500 crash threshold actually mean?
It is the property damage level at which a driver must give immediate notice of the crash to police under 625 ILCS 5/11-407(a), where no officer is already present. It is not a reporting form, not a deadline, and not a measure of whether a claim is worth bringing.
Is the threshold ever lower than $1,500?
Yes. It is $500 where a vehicle involved is subject to Section 7-601, the mandatory insurance provision, but is not covered by a liability insurance policy. Notice is also required for any injury or death, for any crash involving a school bus, and for injuries to someone boarding or just leaving a school bus within 50 feet of it.
Where does the 10-day deadline come from?
625 ILCS 5/11-408, and it applies to law enforcement rather than to you. An officer who investigates a crash or prepares a written report must forward it to the Administrator within 10 days after the investigation. Advice telling drivers to meet a 10-day filing deadline is describing the repealed requirement.
Does the $1,500 threshold matter in a truck accident?
Rarely. A loaded tractor-trailer can weigh up to 80,000 pounds, so any collision worth asking about has already exceeded $1,500 in damage. The threshold decides whether police must be notified, not whether a claim is worth pursuing, and it says nothing about injuries.
What deadlines should I actually worry about after a truck crash?
The evidence ones. A motor carrier must keep an accident register for three years under 49 CFR 390.15(b), but dashcam and facility video is often overwritten within one to two weeks, and vehicles get repaired or salvaged. A written preservation request sent early matters more than any reporting form.
