Chicago underride accident lawyers at Abels & Annes, P.C. represent victims and families affected by some of the deadliest truck crashes on the road. When a passenger vehicle slides beneath the rear or side of a commercial trailer, the crash often causes catastrophic injury or death.
An underride collision shears off the roof of the smaller vehicle or crushes the occupant compartment entirely, bypassing every safety system designed to protect the people inside. Federal regulations require most trailers to be equipped with rear underride guards, and when those guards are missing, damaged, or poorly maintainedthe crash may involve negligence by the trucking company, trailer owner, maintenance provider, or guard manufacturer.
We handle underride accident claims throughout Chicago and Cook County, tracing liability through the truck driver, trucking company, trailer owner, maintenance contractors, and any party responsible for a failed or non-compliant underride guard.

How Our Chicago Underride Accident Lawyers Investigate Truck and Trailer Liability
Underride cases are among the most technically demanding truck accident claims. They require a detailed understanding of trailer safety equipment, federal guard standards, maintenance records, and crash dynamics.
When you hire Abels & Annes, P.C., our team takes over immediately to:
- Examine the underride guard and trailer equipment. We arrange for the rear impact guard, trailer frame, and related components to be inspected and documented before the trucking company or its insurer repairs or disposes of the equipment, which is critical to proving trucking company liability.
- Evaluate compliance with federal safety standards. We determine whether the trailer's rear impact guard met the requirements of FMVSS 223 and 224, whether it was properly maintained, and whether it performed as designed at the time of the crash.
- Preserve electronic and documentary evidence. ECM data, maintenance logs, inspection reports, and dispatch records may all establish how the truck was operating and whether the carrier knew about guard or equipment deficiencies.
- Engage crash reconstruction and engineering professionals. When needed, we work with professionals who analyze impact dynamics, guard performance, trailer visibility, and vehicle intrusion patterns to determine why the underride occurred and who bears responsibility.
- Document catastrophic injuries and lifetime costs. Underride crashes cause devastating injuries. We work with medical and financial professionals to project the full cost of care, lost earning capacity, and non-economic harm across the victim's lifetime.
Every step of this process is designed to show how driver error, equipment failure, or safety violations caused the underride and to build a claim against every liable party.

What Is a Truck Underride Accident?
An underride accident occurs when a passenger vehicle collides with a commercial truck or trailer and slides beneath the larger vehicle's body. Because the undercarriage of a trailer sits well above the hood and windshield of most cars, the smaller vehicle may pass beneath the trailer's frame rather than making contact with the rear or side surface at bumper level.
The result is often fatal or permanently disabling. The roof and upper structure of the passenger vehicle may be sheared off or crushed, exposing occupants directly to the trailer's undercarriage. Standard vehicle safety features, including airbags, crumple zones, and seatbelt systems, are not designed to protect against this type of intrusion.
Underride accidents fall into two primary categories, and each involves different equipment, different regulatory standards, and potentially different liable parties.
Rear Underride Accidents and Rear Guard Failures
A rear underride crash occurs when a vehicle strikes the back of a trailer and slides beneath it. This may happen when a truck stops suddenly, is traveling significantly slower than surrounding traffic, is stopped on a roadway without adequate warning, or is poorly visible due to missing or non-functioning rear lights and reflectors.
Federal law requires most trailers and semitrailers manufactured after January 26, 1998 to be equipped with rear impact guards designed to prevent or reduce underride in rear collisions. These guards, sometimes called Mansfield bars, must meet the performance standards set by FMVSS 223 and the installation requirements of FMVSS 224. When a rear impact guard fails to prevent underride, the question becomes whether the guard met federal standards, whether it was properly maintained, and whether it performed as intended.
Side Underride Accidents and Unsafe Trailer Side Exposure
A side underride crash occurs when a vehicle strikes the side of a trailer and passes beneath it, typically during a truck's turn, lane change, or while the truck crosses an intersection. Side underride crashes are particularly dangerous because the sides of most trailers offer no structural barrier between the trailer's undercarriage and an approaching vehicle.
There is currently no federal rule requiring side underride guards on most commercial trailers, even though NHTSA has studied the issue, and side protection technology is available.
The absence of a federal mandate does not eliminate liability. When a trucking company or trailer owner fails to install readily available side protection, and a side underride crash results, negligence arguments may still apply.
What Causes Chicago Truck Underride Accidents?
Chicago's expressway system funnels heavy commercial trailer traffic through some of the most congested corridors in the Midwest. Routes like I-90/I-94, I-55, and I-80 carry a constant stream of tractor-trailers moving between intermodal yards, distribution centers, and industrial zones. Slower-moving or stopped trailers merging from warehouse access roads, idling on shoulders, or navigating congested ramps create exactly the conditions where underride crashes are most likely to occur.
Other factors that may contribute include:
- Failed or inadequate rear impact guards. A rear underride guard that is corroded, damaged from a prior impact, improperly mounted, or built to outdated standards may collapse or break away on contact rather than preventing underride. Maintenance failures and deferred inspections are common contributing factors.
- Missing or absent side protection. Most trailers on the road today have no side underride guard. When a truck makes a wide turn or crosses an intersection and a vehicle strikes the exposed side of the trailer, there is nothing to prevent underride.
- Poor trailer visibility. Missing, damaged, or non-functioning rear lights, reflectors, and conspicuity tape may make a trailer difficult to see, particularly at night, in rain, or in construction zones. A trailing vehicle that cannot see the trailer in time may be unable to avoid a rear underride collision.
- Sudden stops or slow-moving trucks. A truck that stops abruptly on a highway, travels well below the speed of traffic, or is parked on a roadway without adequate warning creates an underride hazard for vehicles approaching from behind.
- Unsafe lane changes and turns. A truck that changes lanes or turns across traffic without adequate clearance may expose the side of the trailer to oncoming vehicles, creating the conditions for a side underride crash.
Each of these causes truck accident may point to negligence by the driver, the trucking company, the trailer owner, or the party responsible for maintaining the trailer and its safety equipment.
Who May Be Held Liable for a Chicago Underride Accident?
Underride cases frequently involve multiple liable parties. Identifying each of them is critical because the severity of injuries in these crashes demands that every available source of compensation be pursued.
- The truck driver, who may have stopped suddenly, failed to use hazard lights, made an unsafe lane change or turn, or was operating the truck in a manner that created the underride hazard
- The trucking company may be liable for poor driver training, unsafe operating practices, failure to inspect or maintain trailer safety equipment, and broader FMCSA compliance failures
- The trailer owner which may be a different entity than the trucking company. The party that owns the trailer bears responsibility for ensuring its safety equipment, including the rear impact guard, is maintained and functional.
- Maintenance providers responsible for inspecting and repairing the trailer's rear impact guard, lighting, reflectors, and structural components. A maintenance provider that missed or ignored guard damage or deterioration may share liability.
Our truck accident attorneys trace liability through the ownership, maintenance, and operational chain to build claims that reach each party whose negligence contributed to the underride crash.
Compensation in a Chicago Underride Truck Accident Case
Underride crashes produce some of the most severe injuries in all of motor vehicle litigation. The compensation available reflects the catastrophic nature of these collisions.
Economic Damages
Economic damages cover the measurable financial losses that follow an underride crash, like:
- Medical expenses for emergency care, trauma surgery, hospitalizations, rehabilitation, medications, and all future treatment related to the crash
- Lost wages from time away from work during recovery
- Reduced earning capacity when injuries permanently limit the victim's ability to work
- Out-of-pocket costs, including transportation, home modifications, adaptive equipment, and in-home care
The lifetime cost of catastrophic underride injuries, including traumatic brain injuries, spinal cord damage, amputations, and severe disfigurement, can be enormous.
Non-Economic Damages
Non-economic damages address the harm that does not carry a dollar figure but profoundly affects the victim's quality of life, including:
- Pain and suffering from the crash itself, surgeries, rehabilitation, and ongoing physical limitations
- Emotional distress, including PTSD, anxiety, depression, and the psychological impact of catastrophic injury
- Loss of enjoyment of life when permanent disabilities prevent participation in activities, relationships, and daily routines that defined life before the crash
The severity of underride crash injuries often supports substantial non-economic damage awards.
Wrongful Death Damages
When an underride crash proves fatal, Illinois' Wrongful Death Act allows the personal representative of the deceased's estate to pursue a claim on behalf of surviving family members for loss of financial support, loss of companionship, and the grief and emotional suffering experienced by the family.
Can the Trucking Company Blame the Car Driver in an Underride Case?
This is one of the most common defense strategies in underride cases. Trucking companies and their insurers frequently argue that the driver of the smaller vehicle caused the crash by following too closely, driving too fast, or failing to see the trailer.
Under Illinois' modified comparative negligence statute (735 ILCS 5/2-1116), the defense may argue that the driver of the smaller vehicle shares responsibility for the crash. If some fault is assigned, compensation is reduced proportionally. If the victim's share reaches 51% or more, recovery after truck accident may be barred entirely.
Comparative fault does not eliminate the trucking company's liability. It distributes it. In many underride cases, the evidence shows that the guard was missing, damaged, non-compliant, or structurally inadequate. That means the trucking company's negligence turned what might have been a survivable rear-end collision into a catastrophic or fatal truck crash.
At Abels & Annes, P.C., our underride crash lawyers work with accident reconstruction professionals as needed to separate the cause of the initial contact from the cause of the catastrophic outcome. Even when the driver bears some responsibility for the collision itself, the trucking company may bear substantial liability for the severity of the result.
FAQs for Chicago Underride Accident Attorneys
Are side underride guards required on commercial trucks?
There is currently no federal requirement for side underride guards on commercial trailers, although NHTSA has studied the issue and some manufacturers have begun voluntarily installing them. The absence of a federal mandate does not eliminate liability. When readily available side protection could have prevented the crash, negligence arguments may still apply.
What is a Mansfield bar, and why does it matter in an underride case?
A Mansfield bar is a common name for the rear impact guard mounted on the back of a trailer, named after actress Jayne Mansfield, who died in a rear underride crash in 1967. Federal law requires these guards to meet specific strength and performance standards. When a Mansfield bar fails on impact, the question becomes whether the guard met federal standards and whether it was properly maintained.
What evidence is most important in an underride accident case?
The trailer's rear impact guard, its mounting hardware, and the trailer's maintenance and inspection records are critical. ECM data, crash scene photographs, police reports, and reconstruction analysis also play important roles. Because trucking companies may repair or dispose of the trailer quickly, contacting an attorney early is essential to preserving this evidence.
Can families file a wrongful death claim after a fatal underride accident in Illinois?
Yes. When an underride crash proves fatal, Illinois' Wrongful Death Act allows the personal representative of the deceased's estate to pursue a claim on behalf of surviving family members for loss of financial support, loss of companionship, and the grief and emotional suffering experienced by the family. Because underride crashes so often involve fatalities, preserving evidence quickly is critical. Underride guard condition, maintenance records, and truck data may all be altered or lost without prompt legal action.
How long do I have to file an underride accident lawsuit in Illinois?
Illinois generally allows two years from the date of injury to file a personal injury lawsuit under 735 ILCS 5/13-202. For wrongful death claims, the two-year period begins on the date of death rather than the date of the crash, which may differ in cases where a victim survives for a period before succumbing to injuries.
