A collision involving an 80,000-pound commercial tractor-trailer, semi-truck, or heavy freight carrier on a busy St. Louis County highway is devastating. When massive commercial vehicles collide with standard passenger cars, occupants in smaller vehicles face severe, life-altering trauma.
Litigating a commercial truck crash is fundamentally different from a standard auto accident. Commercial motor carriers are backed by team-based corporate defense firms, rapid-response claims investigators, and multi-layered commercial liability insurance policies. Furthermore, proving liability requires an immediate technical investigation into Federal Motor Carrier Safety Administration (FMCSA) safety regulations, driver logbook compliance, and electronic telemetry data.
At The Cagle Law Firm, our personal injury trial attorneys bring the legal resources and technical expertise necessary to hold negligent trucking companies and corporate insurers accountable. While our main law office is located in downtown St. Louis, we routinely represent crash victims and families across Hazelwood, Florissant, Bridgeton, and North St. Louis County.

Hazelwood serves as a major Midwest logistics and distribution hub in North St. Louis County. Situated adjacent to St. Louis Lambert International Airport and anchored by major industrial parks—such as the Hazelwood Logistics Center off North Lindbergh Boulevard and Park 370—heavy commercial truck traffic is constant. Severe tractor-trailer crashes frequently occur along key local corridors:
Interstate 270 (I-270) Beltway: Heavy commuter traffic, rapid lane merging near the N. Lindbergh Boulevard (US-67) and McDonnell Boulevard exits, and high concentrations of freight traffic create frequent rear-end and multi-vehicle pileups.
Interstate 70 (I-70) Corridor: A primary interstate freight route running past airport cargo hubs where high speeds and sudden traffic slowdowns lead to devastating override and rollover collisions.
Missouri Route 370 (MO-370): A major commercial bypass connecting Hazelwood to St. Charles County, heavily utilized by long-haul freight carriers and industrial delivery fleets.
North Lindbergh Boulevard (US-67 / MO-67): Dense commercial stretches carrying heavy tractor-trailers to and from local fulfillment centers, where wide turns and sudden stops lead to severe broadside crashes.
McDonnell Boulevard & Tradeport Drive: Industrial feeder routes where heavy shift-change commuter traffic meets accelerating freight trucks.
Commercial trucking companies and interstate drivers must adhere to strict federal safety rules under Title 49 of the Code of Federal Regulations (49 CFR), enforced by the Federal Motor Carrier Safety Administration (FMCSA).
Winning a commercial truck accident claim requires an attorney who knows how to uncover systemic regulatory violations, including:
Hours of Service (HOS) Compliance (49 CFR Part 395): Federal law limits commercial drivers to strict driving hours to prevent driver fatigue. We subpoena Electronic Logging Device (ELD) records to prove if a driver exceeded mandatory shift limits.
Driver Qualification Files (49 CFR Part 391): Motor carriers must maintain thorough Driver Qualification Files (DQF). We investigate whether a company failed to conduct mandatory background checks, verified medical certifications, or reviewed past traffic violation records.
Vehicle Inspection & Maintenance Records (49 CFR Part 396): Fleet operators must perform routine safety inspections and brake maintenance. We analyze fleet service logs to uncover neglected braking systems, worn tires, or ignored safety recalls.
Electronic Control Module (ECM) “Black Box” Telemetry: Commercial trucks store digital telemetry data regarding speed, brake application, throttle position, and steering inputs prior to impact. We act quickly to issue spoliation letters to prevent trucking companies from wiping this critical proof.
The 6-Month Destruction Loophole: Under federal law, motor carriers are legally allowed to destroy or overwrite daily driver communication logs and dispatch records after just six (6) months if no active legal claim is filed.
The moment a crash occurs on a Eastern Missouri highway, the trucking company dispatches an accident reconstruction team directly to the scene to build a corporate defense. To prevent them from destroying vital electronic evidence, our office immediately issues a formal Spoliation Letter. This legal notice commands the carrier to preserve:
The truck’s Black Box (Event Data Recorder) logs showing exact pre-impact speeds, braking times, and steering angles.
Post-accident mandatory DOT drug and alcohol screening results.
Detailed fleet maintenance and pre-trip inspection reports.
Understanding state civil codes helps protect your legal right to full financial recovery:
Under Missouri Revised Statutes § 304.012, every person operating a motor vehicle on Missouri highways must exercise the highest degree of care. A truck driver or commercial carrier that fails to maintain safe stopping distances, speeds through construction zones, or drives while distracted breaches this statutory duty.
Under RSMo § 537.765, Missouri operates under a pure comparative fault doctrine. Even if a trucking company’s defense team claims you were partially at fault for a collision (alleging improper lane position or speeding), you can still recover financial compensation reduced proportionally by your allocated percentage of fault.
Under Missouri law (RSMo § 537.080), establishes a strict hierarchy of who can bring a wrongful death lawsuit. Class 1 claimants include the surviving spouse, children (or line descendants if the children are deceased), and the parents of the deceased. If no Class 1 individuals exist, the right moves to Class 2, which encompasses siblings and their descendants.
Under RSMo § 516.120, personal injury lawsuits resulting from a commercial motor vehicle crash carry a strict five (5) year statute of limitations from the date of the accident. However, physical evidence—such as skid mark measurements, ECM black box data, and dashcam footage—can disappear within weeks without prompt legal intervention.
Under RSMo § 537.100, you have three (3) year statute of limitations from the date of death of your loved one to file a wrongful death claim in Missouri. Failing to file a claim by this deadline permantly prevents your family from pursuing compensation.
Commercial truck collisions often result in traumatic brain injuries (TBIs), spinal cord damage, severe crush injuries, and permanent disability. Our legal team collaborates with medical specialists, vocational experts, and economic analysts to pursue full recovery under Missouri law for:
Medical Expenses: Emergency room care, trauma surgery, hospitalization, physical rehabilitation, specialized equipment, and lifetime projected medical treatment.
Lost Income & Loss of Earning Capacity: Full reimbursement for missed work days and long-term financial loss if your injuries prevent you from returning to your trade.
Pain and Suffering: Non-economic damages for physical pain, emotional trauma, disfigurement, disability, and loss of life quality.
Property Damage: Full repair costs or fair market replacement value for your motor vehicle and personal property.
Call 911 Immediately: Ensure law enforcement officers from the St Louis County Police, Hazelwood Police Department (415 Elm Grove Lane) or Missouri State Highway Patrol Troop C respond to secure the scene and document USDOT carrier numbers.
Seek Emergency Trauma Care: Adrenaline can mask severe internal bleeding or concussions. Seek immediate evaluation at nearby regional trauma centers, such as SSM Health DePaul Hospital (12303 DePaul Dr, Bridgeton), Christian Hospital (11133 Dunn Rd, St. Louis), or Northwest HealthCare (1225 Graham Rd).
Document Scene Evidence: Photograph all vehicles, USDOT and MC numbers printed on the truck cab, skid marks, road hazards, and physical injuries.
Avoid Giving Recorded Statements to Freight Adjusters: Commercial trucking insurers deploy risk managers quickly to minimize corporate liability. Speak with an attorney before making official statements.
There is no average compensation for an 18-wheeler accident in Missouri. Large truck collisions usually result in serious, costly injuries, thus more compensation is needed to cover the losses of the victim. Accidents involving 18-wheelers are often much more serious and result in costly injuries.
Truck accidents are so serious for several reasons, including:
An attorney is crucial when dealing with a truck accident case.
The amount of time a truck accident case takes varies. If you have serious injuries, your case will likely take longer simply because it takes longer for you to physically recover. Serious injuries require a great deal of medical treatment and medical experts can only assess progress and healing over time. Time and evaluation of results to physical recovery help assess your financial losses. Whether liability is clear or contested may affect the willingness of the insurance carrier to negotiate.
A case resolving quickly if you are seriously injured is often not in your best interest. Insurance companies are quick to offer a settlement before you have time to discover to extent of your injuries. They know that once an offer is accepted, you cannot make further claims regardless of what physical complications may arise. Rushing a settlement in your serious injury case is not always helpful to you. Likewise, you do not want an attorney that is passive about seeking compensation. As each person is unique, you want an attorney that leverages time and resources on your behalf to maximize deserved compensation.
We work on a contingency fee bases, which means you pay no upfront fees and your attorneys only get paid if they win. Contingency fee agreements are beneficial to the client as the attorney assumes the risks and expenses of requesting medical records, costs of investigations, expert evaluation testimony and litigation fees. Since our attorneys operate under a contingency agreement, we only get paid when we get results for our clients.
