Sharing the road with commercial trucks is part of everyday driving in Chicago, but when a crash happens, the consequences for people in passenger vehicles can be severe. The size and design of trucks mean that even a single mistake can lead to life-altering injuries for drivers and passengers in nearby cars.
Some truck accidents are especially dangerous. Underride crashes, jackknife accidents, rollovers, and wide-turn collisions often happen without warning and can involve multiple vehicles. These crashes may bypass the safety features people rely on in their cars and frequently lead to head injuries, spinal damage, or fatal injuries.
If you or someone you love was hurt in a truck crash, learning how these accidents happen can help you decide what to do next. When a collision is caused by unsafe driving, poor maintenance, or violations of federal safety rules, you may be able to pursue compensation.

Key Takeaways About Dangerous Truck Accidents
- Underride collisions rank among the deadliest types of truck crashes because the trailer bypasses a car’s safety features and intrudes directly into the passenger compartment.
- Jackknife accidents occur when a truck’s trailer swings outward, sweeping across multiple lanes and creating multi-vehicle pileups on busy roadways.
- Federal regulations limit how long truckers may drive without rest, and violations of these rules contribute to fatigue-related crashes with severe consequences.
- Illinois law generally gives injury victims two years from the date of a crash to file a lawsuit, making prompt action a wise choice.
- Liability in commercial truck collisions often extends beyond the driver to include the trucking company, cargo loaders, and maintenance providers.
Why Are Underride Accidents So Dangerous?
An underride crash occurs when a passenger vehicle slides beneath a truck trailer. The trailer bypasses the vehicle’s crumple zones and airbag sensors and enters the passenger compartment, often causing severe head and neck injuries.
The U.S. Government Accountability Office reports that underride crashes involving large trucks resulted in an average of 219 deaths per year between 2008 and 2017. While these crashes account for a small share of total traffic fatalities, they carry a high risk of fatal injury.
Rear Underride Crashes and Guard Limitations
Federal regulations require rear underride guards on newly manufactured trailers. These guards are intended to reduce the risk of vehicles sliding underneath in rear-end collisions.
Guard performance varies, and older trailers may have weaker designs. Corrosion, damage, and poor maintenance can further reduce effectiveness, increasing the risk of trailer intrusion into the passenger compartment.
Side Underride Crashes
Side underride crashes occur when a vehicle strikes the side of a trailer, often at intersections or during lane changes. Federal law generally does not require side underride guards. The open space between a trailer’s wheels can allow a vehicle to pass beneath the trailer body, leading to severe injuries.
Factors that increase the severity of underride crashes include differences in vehicle height, failure of airbags to deploy, direct contact with the trailer structure, and limited trailer visibility at night.
How Jackknife Truck Accidents Occur on Chicago Highways
A jackknife crash occurs when a trailer swings out of alignment with the cab, blocking lanes of traffic and striking nearby vehicles. On heavily traveled routes such as the Dan Ryan Expressway, the Kennedy Expressway, and Interstate 80, these crashes often involve multiple vehicles.
Common Causes of Jackknife Crashes
Sudden braking is a common cause of jackknife accidents, particularly when traction is reduced by weather conditions. Ice, snow, and wet pavement increase the risk when drivers do not adjust speed or braking.
Additional contributing factors may include uneven cargo loading, brake system problems, sharp steering maneuvers, and driver fatigue or inattention. Driver training and proper vehicle maintenance play an important role in reducing these risks.
What Causes Truck Rollover Crashes and Their Catastrophic Injuries
A rollover occurs when a truck tips onto its side or completely overturns. These crashes pose dangers not only to the truck’s occupants but to every vehicle nearby. A rolling tractor-trailer may crush cars in adjacent lanes, block the entire roadway, or spill hazardous cargo across the highway.
Rollovers frequently occur on curved highway ramps, where trucks traveling too fast lose balance and tip. The elevated interchanges connecting Chicago’s expressway system, including the Circle Interchange and the Jane Byrne Interchange, see regular truck traffic navigating tight curves.
Factors That Lead to Rollover Accidents
Speed is a primary factor in many rollover crashes. Trucks have a higher center of gravity than passenger vehicles, making them more susceptible to tipping when cornering too fast. A driver who fails to slow down before entering a curve may find the trailer leaning past its tipping point.
Cargo loading also affects rollover risk. A top-heavy load or cargo that shifts during transit raises the truck’s center of gravity and reduces stability. Federal regulations require proper load securement, but violations occur when shippers prioritize speed over safety.
The following factors frequently appear in rollover crash investigations:
- Excessive speed on curves, ramps, or uneven road surfaces.
- Improperly loaded or unsecured cargo that shifts during turns or sudden maneuvers.
- Tire blowouts that cause sudden loss of control at highway speeds.
- Overcorrection by fatigued or distracted drivers who drift off the road and jerk the wheel.
- High crosswinds on bridges and open stretches of highway that push against tall trailers.
Rollover crashes often involve significant property damage, road closures, and hazardous material spills that affect entire communities.
When Do Override Truck Accidents Occur?
An override crash is the opposite of an underride collision. It occurs when the front of a truck rides up and over a smaller vehicle ahead, crushing it beneath the cab or undercarriage. These accidents happen most often in heavy traffic or at intersections where vehicles stop suddenly.
Because of their size and weight, commercial trucks require much greater stopping distances than passenger cars. A fully loaded tractor-trailer traveling at highway speed may need the length of two football fields to come to a complete stop under ideal conditions. Wet or icy roads extend that distance even further.
Driver Fatigue and Distraction Behind Override Collisions
Distraction, fatigue, and following too closely are leading contributors to override collisions. A trucker who takes their eyes off the road to check a phone, adjust a GPS device, or reach for something in the cab may not notice slowing traffic until it is too late.
The Federal Motor Carrier Safety Administration limits how long truckers may drive before taking required rest breaks. Despite these rules, pressure to meet delivery deadlines sometimes pushes drivers and carriers to exceed legal limits. A fatigued driver has slower reaction times and may fail to brake in time to avoid a collision.
Brake maintenance also plays a role. Worn brake pads, malfunctioning air brake systems, and inadequate pre-trip inspections allow brake problems to go unaddressed until a crash reveals the failure.
How Blind Spot Collisions Lead to Serious Truck Accidents
Commercial trucks have large blind spots on all four sides where the driver has limited or no visibility. These areas, sometimes called no-zones, extend along the sides of the trailer, directly behind the truck, and in front of the cab.
When a truck driver changes lanes or merges without seeing a vehicle in a blind spot, a sideswipe collision may result. The size and weight of the truck may push a smaller vehicle off the road, into a barrier, or into oncoming traffic.
Where Truck Blind Spots Create the Greatest Danger
The right side of a tractor-trailer presents the largest blind spot, often extending across two or more lanes. A car traveling in this zone for an extended period is invisible to the driver, and a sudden lane change may catch the smaller vehicle off guard.
The rear blind spot extends approximately 30 feet behind the trailer, meaning a driver cannot see vehicles following too closely. Tailgating a truck eliminates your ability to see traffic ahead and leaves no time to react if the truck brakes suddenly.
Vehicles directly in front of a truck may also be difficult to see, especially low-profile cars sitting close to the cab. A truck that accelerates forward at a stoplight or intersection may not notice the car ahead until contact occurs.
Blind spot collisions frequently involve these dangerous scenarios:
- Lane changes without proper mirror checks or signal use.
- Merging into traffic without accounting for vehicles in adjacent lanes.
- Right turns at intersections where cyclists or pedestrians occupy the blind zone.
- Backing maneuvers in parking lots, loading docks, or construction zones.
Truckers receive training on checking mirrors and accounting for blind spots, but rushed schedules and distracted driving lead some to skip these safety steps.
Why Wide Turn Accidents Happen in Urban Areas
Tractor-trailers need extra space to complete turns, especially right turns at intersections. The trailer tracks inside the path of the cab, which means the truck must swing wide to the left before turning right. This maneuver creates a danger zone between the truck and the curb where pedestrians, cyclists, and vehicles may become trapped.
Chicago’s downtown streets, with their busy intersections and narrow lanes, present particular challenges for truckers making wide turns. The Loop, River North, and South Loop neighborhoods see heavy delivery traffic throughout the day, increasing the risk of turn-related collisions.
A turn-related crash may occur when:
- A truck driver fails to signal intentions clearly, leading other motorists to misread the maneuver.
- A vehicle attempts to pass on the right while a truck is initiating a turn.
- A pedestrian or cyclist enters the intersection without realizing the truck is about to turn across their path.
- The driver misjudges the turning radius and clips vehicles or structures in adjacent lanes.
Truckers receive training on how to execute wide turns safely, but rushed schedules and distracted driving lead some to cut corners. A truck accident lawyer may investigate whether proper procedures were followed when a wide turn collision causes injuries.
