Truck Accidents
When a collision with a commercial truck leaves you facing uncertainty, we're here to help you take the next step.
Semi-trucks and commercial tractor-trailers are the largest and most dangerous vehicles on the road. Due to their size, weight, and stopping distance, collisions involving these vehicles can result in catastrophic injuries, permanent disabilities, or fatalities.
While federal and state regulations govern trucking safety, serious accidents continue to occur when drivers, trucking companies, maintenance providers, or equipment manufacturers fail to meet their responsibilities.
In some cases, collisions involve not only negligent driving but also failures in vehicle safety systems, defective components, or inadequate crash avoidance technology.
At Casey & Devoti, we represent individuals and families affected by serious trucking collisions. Our St. Louis truck accident lawyers investigate every aspect of a crash to determine what happened, identify all responsible parties, and pursue accountability for the devastating harm caused by these accidents.
How Do Truck Accidents Happen?
According to data from the National Safety Council, 120,724 large trucks were involved in crashes resulting in an injury in 2024. Commercial truck drivers operate under demanding schedules and strict delivery deadlines. While federal regulations limit driving hours and establish safety requirements, violations and unsafe practices continue to contribute to serious crashes.
Due to the size and weight of commercial vehicles, even a momentary lapse in judgment can lead to catastrophic consequences for occupants of passenger vehicles.
Common causes of trucking accidents include:
- Driver fatigue and hours-of-service violations
- Distracted or inattentive driving
- Speeding or aggressive driving behavior
- Improper truck maintenance
- Brake failures and mechanical defects
- Overloaded or improperly secured cargo
- Inadequate driver training or supervision
- Unsafe lane changes and merging practices
As trucking technology continues to evolve, some collisions involve more factors than driver negligence alone. Modern commercial vehicles may be equipped with advanced driver-assistance systems (ADAS), collision mitigation technology, automatic emergency braking systems, lane departure warnings, and other crash avoidance systems designed to reduce the risk of accidents.
When these systems fail to operate as intended, or when a trucking company fails to properly maintain or update critical safety equipment, questions of product liability and vehicle safety system performance may become central to the investigation.
Investigating Trucking Accident Cases
Truck accident claims in eastern Missouri and southern Illinois are more complex than standard motor vehicle crashes because multiple parties may share responsibility for a crash.
Liability may extend beyond the driver to include:
- Trucking companies
- Fleet operators
- Maintenance contractors
- Cargo loading companies
- Vehicle manufacturers
- Component and equipment manufacturers
Our truck crash attorneys conduct detailed investigations designed to uncover the full cause of a collision. This process may include reviewing:
- Driver logbooks and hours-of-service records
- Electronic logging device (ELD) data
- Maintenance and inspection records
- Trucking company safety policies
- Federal Motor Carrier Safety Administration compliance records
- Black box and event data recorder information
- Driver qualification files
- Witness statements
- Accident reconstruction reports
We may also analyze electronic vehicle data, crash avoidance system performance, braking system operation, onboard safety technology, and maintenance histories to determine whether a vehicle technology failure contributed to the crash.
These investigations usually uncover evidence that is not immediately apparent in the days following an accident and can be critical to establishing negligence and liability.

How to Build a Strong Truck Accident Injury Claim
Truck accident injury cases frequently involve catastrophic damages and life-changing consequences for victims and their families.
Since the stakes are so high, these claims require extensive medical documentation, expert testimony, accident reconstruction analysis, and detailed financial projections regarding future losses.
Our attorneys regularly handle cases involving:
- Multi-vehicle highway collisions
- Jackknife accidents
- Rollover crashes
- Underride collisions
- Rear-end crashes involving commercial vehicles
- Cargo-related accidents
- Catastrophic injury claims
- Wrongful death claims
Insurance companies representing trucking carriers deploy investigators immediately after a crash occurs. Their goal is frequently to limit liability and minimize payouts.
Early legal involvement can help preserve evidence, protect driving and maintenance records, and make sure that victims have a strong advocate working on their behalf from the beginning.

Compensation in Truck Accident Cases
Truck accident claims are intended to address both the financial losses and personal hardships caused by a serious injury. Depending on the circumstances, compensation may include:
- Emergency medical treatment
- Hospitalization and surgery
- Ongoing medical care
- Rehabilitation and therapy
- Lost wages
- Reduced future earning capacity
- Pain and suffering
- Emotional distress
- Loss of quality of life
- Long-term disability expenses
- Funeral and burial costs in wrongful death cases
The value of a claim depends on the severity of injuries, the extent of financial losses, and the long-term impact on the victim and their family.
