Why a Truck Crash Case Is Not a Car Crash Case

A truck case is harder, slower and worth more than a car case, and the reasons are structural. Six things change the moment the other vehicle is a tractor-trailer.

The weight is not close

A tractor-trailer can legally weigh 80,000 pounds on the Interstate System, with 20,000 pounds on any single axle and 34,000 on a tandem axle (23 CFR 658.17). Trucks at the heavier end of the range can weigh 20 to 30 times as much as a passenger car (Insurance Institute for Highway Safety, Fatality Facts: Large Trucks, 2024 data, posted June 2026). Physics decides most of the outcome before anyone hits the brakes.

The people who die are almost never in the truck

This is the single most important number on this page. Of the 5,340 people killed in large truck crashes in 2024, 62 percent were occupants of cars and other passenger vehicles. Seventeen percent were occupants of the truck. Nineteen percent were pedestrians, bicyclists or motorcyclists (IIHS, 2024 data, posted June 2026). The truck driver usually walks away. You usually do not.

A federal rulebook applies

Interstate trucking is governed by the Federal Motor Carrier Safety Regulations. Missouri adopted 49 CFR Parts 390 through 397 for commercial vehicles operating inside the state as well, and the Missouri State Highway Patrol enforces them (RSMo 307.400). That means a violation is not just bad driving. It is a documented breach of a written safety standard, and it is evidence.

There is usually more than one defendant

A car crash has a driver and an insurer. A truck crash can involve the driver, the motor carrier, the company that owned the tractor, a different company that owned the trailer, a freight broker, a shipper, whoever loaded the cargo, and a maintenance contractor. Each may carry separate insurance.

The defense starts before you do

Motor carriers and their insurers investigate serious crashes immediately. That is their job and it is not improper. It does mean that by the time you are out of surgery, someone has already photographed the scene, interviewed the driver and started building the company's version of what happened.

The evidence has a shelf life

Most of the proof in a truck case sits on the company's servers and in the company's files, and federal rules only require it to be kept for a set period. Driver vehicle inspection reports have to be retained for three months (49 CFR 396.11). Logs and ELD back-ups, six months (49 CFR 395.8, 395.22). After that, destroying them on schedule is lawful. This is why the first phone call matters more in a truck case than in any other kind of crash.

What to Do After a Truck Accident in Kansas City

If you are reading this from a hospital bed or on behalf of someone who is, start at step two. Nothing here has to happen today.

1. Call 911 and let officers document the scene. If the crash happened inside the Kansas City limits, the Kansas City Police Department almost always investigates and holds the report, and that includes crashes on I-70, I-435, I-35, I-29, I-670 and Bruce R. Watkins Drive within the city. The Missouri State Highway Patrol works highways outside municipal limits, in unincorporated Jackson, Clay, Platte and Cass counties, and in smaller cities that ask for help. Which agency it was decides where you request the report.
2. Get medical care the same day, even if you feel alright. Adrenaline hides injuries. Kansas City has three Level I trauma centers for adults: University Health Truman Medical Center at 2301 Holmes Street, Research Medical Center at 2316 East Meyer Boulevard, and Saint Luke's Hospital of Kansas City at 4401 Wornall Road. Children's Mercy Hospital at 2401 Gillham Road is the region's Level I pediatric trauma center (Missouri Department of Health and Senior Services trauma center designations). A gap between the crash and your first visit is the first thing an adjuster will point at.
3. Photograph what you safely can. The tractor and trailer, the company name and USDOT number on the door, the license plates, the damage, the road, the weather, your injuries. The USDOT number alone lets a lawyer pull the carrier's federal safety record.
4. Get names. Witnesses leave. A phone number written down at the scene is worth more than a police report six weeks later.
5. Do not give the trucking company's insurer a recorded statement. You are not required to. More on this below.
6. Request the crash report. From the Kansas City Police Department, reports become available to the public 20 business days after the incident, through the department's online report request portal, in person at a patrol division station with photo ID, or by mail to KCPD, Attn: Criminal Records Section, 1125 Locust, Kansas City, MO 64106. Call KCPD Criminal Records at 816-234-5100 to confirm a report exists before you drive there, and be aware that mail and online turnaround currently runs several months. From the Missouri State Highway Patrol, wait ten days from the date of the crash investigation, then request it through the Patrol's records portal or by writing to the Patrol Records Division, Attention: Traffic Crash Reports, P.O. Box 568, Jefferson City, MO 65102. The fee is $6.00 per basic crash report.
7. Call a lawyer before the evidence clock runs out. Preserving records is time-sensitive in a way that has nothing to do with the filing deadline.

The Evidence That Disappears, and the Letter That Stops It

A truck carries proof that a passenger car simply does not have. Almost all of it belongs to the trucking company, and almost all of it has an expiration date written into federal law.

What exists in a truck case

• Engine control module and event data recorder downloads: speed, brake application, throttle position and hard-braking events in the seconds before impact
• Electronic logging device records and records of duty status, showing how long the driver had been working
• Dashcam and in-cab camera footage
• GPS and telematics data tracking the truck's route and stops
• Bills of lading, dispatch records and trip envelopes
• The driver qualification file: application, motor vehicle record, road test, annual review, medical certificate
• Post-crash drug and alcohol test results
• Maintenance records, annual inspections and driver vehicle inspection reports
• Weigh station and roadside inspection records
• The tractor and trailer themselves, before they are repaired, sold or scrapped

How long the rules require the company to keep it

Read that table next to the Missouri filing deadline. You have five years to file a personal injury suit (RSMo 516.120). The inspection report that would show the brakes were written up the week before can be gone in three months. Waiting to hire a lawyer does not cost you the lawsuit. It can cost you the proof.

What a preservation letter does

A preservation letter, sometimes called a spoliation letter, is a written demand sent to the motor carrier and its insurer identifying the specific records, data and physical evidence that must be kept and not destroyed, altered or repaired. It converts routine document destruction into a decision the company has to make knowingly. Missouri does not recognize a separate lawsuit for destroying evidence, but Missouri courts do recognize an adverse inference against a party that intentionally destroys evidence in bad faith, following Brown v. Hamid, 856 S.W.2d 51 (Mo. banc 1993). A letter on file is what turns a shrug into a problem.

What the Trucking Company Is Doing While You Recover

None of what follows is illegal. All of it is normal. You should just know it is happening.

Investigators go to the scene

Large motor carriers and their insurers respond to serious crashes quickly, often with a team that includes an adjuster, an investigator and defense counsel. They photograph the scene, measure it, download the truck's electronic data, take the driver's account while it is fresh and secure the vehicle. By the time you have been discharged, the company has a documented version of events and you have a hospital bracelet.

An adjuster calls, and sounds helpful

The call usually comes within days. It is friendly. There may be an offer to cover your rental, or a check for your car. What is being built is a record, and a relationship in which you talk to them directly rather than through a lawyer.

The recorded statement

You are not required to give the other side's insurer a recorded statement. What sounds like a courtesy is a deposition without a lawyer present. Innocent answers become problems later: "I'm fine" said on day two, before the disc herniation showed on imaging, gets read back to a jury on day 700.

The early offer

An offer that arrives before you finish treatment cannot account for what treatment will cost. FMCSA puts the average comprehensive cost of a fatal commercial vehicle crash at $15,216,588, and an injury crash at $330,946 in 2023 dollars (FMCSA Crash Cost Methodology, 2025 update, published February 2026). Early offers are rarely in that neighborhood, and once you sign a release, it is over.

The blanket medical authorization

A broad authorization lets the insurer pull your entire medical history, not just records related to this crash. That is how a twenty-year-old back complaint becomes their explanation for your injury.

Who Can Be Held Responsible for a Truck Crash

Finding every responsible party is most of the work in a truck case, because each one may carry separate insurance.

What about a defective part?

If a tire, coupling or brake component failed, that can point toward the manufacturer. Horn Law handles motor vehicle accident claims. We do not take product liability cases. In a crash where a component may have failed, we evaluate and pursue the motor vehicle claim and will tell you plainly if something falls outside what we handle, rather than sitting on it.

The same is true of a few other situations that look adjacent to a truck case. If you were the trucker and were hurt on the job, or you were injured on a loading dock rather than on the road, that is not a claim we take. Call anyway. A five minute conversation is better than guessing, and we would rather point you in the right direction than leave you without one.

The Federal Safety Rules That Decide These Cases

Here is why these rules matter to your claim. A violation is evidence. It moves the argument from "the driver was careless," which is a matter of opinion, to "the driver broke a written federal safety standard," which is a matter of record. And when the records show a pattern rather than a single lapse, that can support a claim against the company itself rather than only the driver.

How long a driver can be behind the wheel

A property-carrying driver may drive up to 11 hours after 10 consecutive hours off duty, and may not drive past the 14th consecutive hour after coming on duty. Driving is not permitted once 8 hours of driving time have passed without a 30-minute interruption of driving status, which can be off-duty time, sleeper berth time, or on-duty time that is not driving. Weekly, a driver is capped at 60 hours in 7 days if the carrier does not run every day of the week, or 70 hours in 8 days if it does, and either period can end with 34 or more consecutive hours off duty (49 CFR 395.3).

Two flexibilities sit in a different section, and both get misquoted. A driver may split the required 10 hours into two rest periods, neither shorter than 2 hours, one of them at least 7 consecutive hours in the sleeper berth, together totaling at least 10 hours (49 CFR 395.1(g)(1)(ii)). And a driver may go up to 2 hours past the limits where adverse driving conditions prevent safe completion of the run, but only where those conditions could not reasonably have been known to the driver or the dispatcher before the run began (49 CFR 395.1(b)(1), 395.2). That last qualifier is often where a fatigue case is won or lost.

The electronic logging device

Most interstate drivers who are required to keep records of duty status must record them on an electronic logging device, which synchronizes with the vehicle's engine and is far harder to falsify than a paper logbook. There are real exceptions, and one of them matters in Kansas City: a short-haul driver operating within a 150 air-mile radius who qualifies under 49 CFR 395.1(e)(1) is excepted from the logging rules altogether, so a container chassis running a short loop out of an intermodal yard may have no ELD data at all. Where records do exist, the carrier must keep records of duty status and supporting documents for at least six months (49 CFR 395.8(k)(1)), and must keep a back-up copy of ELD records on a separate device for six months (49 CFR 395.22(i)).

Whether the driver should have been hired at all

Before a driver takes the wheel, the carrier must build and keep a qualification file: the employment application, the motor vehicle record from each licensing authority, a road test certificate or accepted equivalent, the annual driving record inquiry and the note of the annual review, and proof of medical certification. For a CDL holder, which covers almost every tractor-trailer driver, the carrier now meets the medical requirement with the CDLIS motor vehicle record showing medical certification status. The file itself must be kept for as long as the driver is employed and three years after (49 CFR 391.51(c)). There is a catch worth knowing: the same rule lets the carrier purge the annual inquiries, the review notes and the medical documents three years after each one was executed, even while the driver is still on the payroll (49 CFR 391.51(d)). For a long-serving driver, the early years can be lawfully gone.

Drug and alcohol testing after a crash

Post-crash testing is mandatory, but only in defined circumstances, and the details decide whether a missing test is suspicious or simply lawful. If the crash killed someone, the carrier must test any surviving driver who was performing safety-sensitive functions, and no citation is needed. Otherwise a test is required only if the driver receives a citation for a moving traffic violation arising from the crash, and the crash either caused bodily injury to someone who immediately received medical treatment away from the scene, or left a vehicle with disabling damage that had to be towed away. The citation windows are different for each test: 8 hours for alcohol, 32 hours for drugs. The alcohol test must be attempted within 8 hours, with a written record of the reasons if it was not done within 2 hours, and the controlled substances test within 32 hours (49 CFR 382.303). Whether the test happened, and how fast, is often as revealing as the result.

Inspection, repair and maintenance

Carriers must systematically inspect, repair and maintain every vehicle under their control. Maintenance records are kept for one year where the vehicle is housed, and six months after the vehicle leaves the carrier's control (49 CFR 396.3(c)). Drivers inspect at the end of each day, but they are only required to write a report if they found, or were told about, a defect in the service brakes, parking brake, steering, lighting devices and reflectors, tires, horn, wipers, mirrors, coupling devices, wheels and rims, or emergency equipment. If nothing was found, no report exists at all. Where one does exist, the carrier keeps it, the certification of repairs and the driver's review for three months (49 CFR 396.11(a)(2), (a)(4)), and since March 2026 it may be kept electronically (49 CFR 396.11(a)(6)). The absence of a report is itself a fact worth examining.

Securing the load

Cargo must be loaded and secured to prevent it from leaking, spilling, blowing or falling from the vehicle, and to prevent it from shifting inside the vehicle enough to affect stability or handling (49 CFR 393.100). Tiedowns and their attachment points must be designed, installed and maintained so the forces on them stay within their breaking strength at 0.8g of deceleration forward and 0.5g of acceleration rearward and laterally, and within their working load limit at 0.435g forward, 0.5g rearward and 0.25g laterally (49 CFR 393.102(a)). The aggregate working load limit of the tiedowns must be at least half the weight of what is secured (49 CFR 393.106(d)). A shifting load is a rollover waiting for a curve.

Weight

On the Interstate System, the maximum gross vehicle weight is 80,000 pounds, with 20,000 pounds on a single axle and 34,000 on a tandem axle, subject to the Federal Bridge Formula (23 CFR 658.17). Overweight trucks take longer to stop.

What the data says about causes

In two-vehicle crashes between a large truck and a passenger vehicle, the truck was assigned the critical reason 44 percent of the time and the passenger vehicle 56 percent. Across the whole study, covering single-vehicle and multi-vehicle crashes together, the critical reason was assigned to the truck in 77,000 of 141,000 cases, and of those it traced to the driver 87.2 percent of the time, to the vehicle 10.1 percent and to the environment 2.3 percent. Looking at all 141,000 trucks regardless of fault, brake problems were present in 29.4 percent, traveling too fast for conditions in 22.9 percent, and fatigue in 13.0 percent (FMCSA, Report to Congress on the Large Truck Crash Causation Study, March 2006). Two caveats. "Critical reason" is not the same thing as legal fault. And that study is the most detailed of its kind but it is old, so it is cited here for the shape of the problem, not for current-year rates.

Types of Tractor-Trailer Crashes We Handle

This page covers crashes involving tractor-trailers and other heavy commercial vehicles operated by motor carriers: semis, 18-wheelers, big rigs, tankers, flatbeds, car haulers, dump trucks and similar Class 7 and Class 8 vehicles subject to federal motor carrier regulation.

Injuries in Truck Crashes and What They Cost

Truck crash injuries skew catastrophic because the energy involved is an order of magnitude higher than in a car-to-car collision. The injuries below are the ones that turn a claim into a lifetime financial problem.

• Traumatic brain injury. From concussion with lasting cognitive symptoms through severe TBI requiring permanent supervised care.
• Spinal cord injury and paralysis. Paraplegia and tetraplegia bring home modification, adaptive equipment, attendant care and a shortened working life.
• Amputation. Crush injuries and underride crashes. Prosthetic replacement recurs every few years for the rest of a life.
• Burns. Fuel tank ruptures and cargo fires. Grafting, scar revision and infection risk over years.
• Internal organ damage. Often not visible at the scene and sometimes not diagnosed on the first hospital visit.
• Multiple trauma. Several serious injuries at once, where each complicates the treatment of the others.
• Death. In 2024, 5,340 people died in large truck crashes, and 62 percent of them were in passenger vehicles (IIHS, 2024 data, posted June 2026).

The two numbers that decide the value of a serious case are future medical care and lost earning capacity, and both need expert proof rather than estimates. FMCSA's own cost model puts the average comprehensive cost of a fatal commercial vehicle crash at $15,216,588 and an injury crash at $330,946 in 2023 dollars (FMCSA Crash Cost Methodology, 2025 update, published February 2026). Those are population averages used for federal policy analysis, not a prediction about any individual case, but they show the gap between what a serious truck injury actually costs and what an early insurance offer typically looks like.

Missouri Law That Affects Your Truck Accident Claim

Who files a wrongful death claim in Missouri

Missouri sets an order. The first class is the spouse, the children or the surviving lineal descendants of any deceased children, or the parents of the deceased. If no one in that class exists, the claim passes to siblings or their descendants. If neither class exists, the court appoints a plaintiff ad litem (RSMo 537.080). Only one action may be brought against any one defendant for the death of any one person. That one-action rule is the reason families need to talk to each other, and to a lawyer, early. A settlement by one family member can foreclose the others.

Kansas City sits on a state line, and that changes things

Truck traffic here is interstate by nature, and a crash a few miles west of the state line is a different case. Where the crash happened, where the motor carrier is based and registered, and where its registered agent sits all bear on where a case can be filed and which state's law applies. Kansas rules on fault and filing deadlines are not the same as Missouri's. If your crash happened in Kansas, or the carrier is based elsewhere, that is a question to ask early rather than after a deadline passes.

Why Bigger Insurance Policies Mean a Harder Fight

Federal law requires far more of a motor carrier than Missouri requires of a driver. A for-hire carrier operating in interstate commerce and hauling non-hazardous property in a vehicle rated 10,001 pounds or more must maintain at least $750,000 in financial responsibility. Carriers hauling oil and most other listed hazardous materials must carry $1,000,000. A $5,000,000 floor applies to bulk shipments of explosives, poison gas and certain other listed materials, and to highway route controlled quantities of radioactive material in any amount (49 CFR 387.9). These are minimum financial responsibility levels, which a carrier can meet with insurance, a surety bond or self-insurance, so they are a floor rather than a policy limit. Many carriers buy layered and excess coverage well above them.

That is good news and bad news. More coverage means a serious injury can actually be paid. It also means the insurer has far more at risk, so the case is defended much harder than a fender bender: earlier investigation, defense counsel from the start, retained experts, and a willingness to try the case rather than pay it.

The MCS-90 endorsement

You may see the MCS-90 mentioned and described as a guarantee that someone will pay. It is not that, and the difference matters. The MCS-90 is an endorsement attached to a motor carrier's policy under 49 CFR Part 387 in which the insurer agrees to pay a final judgment against the insured for public liability arising from negligence in the operation, maintenance or use of vehicles subject to the federal financial responsibility rules, even if the vehicle is not described in the policy, and even if the carrier has broken the terms of its own policy. Four limits are worth knowing. It pays only up to the federal minimum, not the full policy limit. Most courts treat it as a last resort, so it is generally not triggered where other available insurance already covers the federal minimum. It operates on a final judgment rather than a settlement, and courts disagree about how strictly that applies. And the insurer has a contractual right to be reimbursed by the carrier for what it pays out. It is a safety net for the public, not a shortcut for your claim.

Kansas City Truck Traffic and Where Crashes Happen

Kansas City has more heavy truck traffic than a metro its size would otherwise carry, because it is a national freight hub. MoDOT describes Kansas City as the largest rail hub in the nation in terms of tonnage, second only to Chicago by volume of carloads. Four of North America's six Class I railroads serve the region (BNSF, Union Pacific, Norfolk Southern and CPKC), alongside regional and short-line carriers. Trucks moved 149.8 million tons of freight worth $197.4 billion through the region in 2019, and the freight industry supports more than 100,000 regional jobs (MoDOT Kansas City District Freight Plan; MARC Connected KC 2050 freight chapter, 2019 data). Rail hubs generate truck traffic. Intermodal terminals and warehouse corridors feed trucks onto the same interstates you commute on.

The corridors

• I-70. The main east-west freight route through the metro. MoDOT's Kansas City District Freight Plan identifies I-70 as top priority for capacity upgrades. Two of Horn Law's published truck results came from I-70 crashes.
• I-435. The outer loop, and the route many carriers use to skirt downtown. MoDOT flags the south leg for freight capacity.
• I-35. The north-south corridor running from the Kansas line up through the Northland.
• I-29. North of the river toward the airport and the warehouse and distribution corridor around it.
• I-635. The short connector across the state line, heavily used by carriers moving between Missouri and Kansas terminals.
• US-71 (Bruce R. Watkins Drive). A high-speed arterial through the city with signalized intersections, a difficult combination for a loaded truck.
• The interchanges. I-70 at I-435, I-35 at I-435, I-29 at I-635, and the downtown loop where I-70 and I-670 split. Merging, weaving and heavy trucks in the same few hundred yards.

The numbers

Missouri's commercial motor vehicle fatality rate was 1.11 per 100 million vehicle miles traveled in 2025, down from 1.29 the year before, with 21 fewer CMV-involved fatalities than in 2024 (MoDOT Tracker, Fatalities Involving Commercial Motor Vehicles). Statewide, there were 136,847 traffic crashes in 2023, with 991 people killed and 50,375 injured, and Jackson County recorded the most traffic fatalities of any Missouri county at 132 (Missouri State Highway Patrol, Missouri Traffic Crashes 2023 Statistics). One honest limitation: Missouri does not publish a Jackson County or Kansas City metro figure isolating commercial motor vehicle crashes, so the statewide commercial figures above are the closest reliable data, and the Jackson County number covers all traffic fatalities, not truck crashes specifically.

Nationally, 5,837 large trucks were involved in fatal crashes and roughly 120,000 in injury crashes in 2022, both up on the prior year (FMCSA, Large Truck and Bus Crash Facts 2022, published September 2025).

How Compensation Is Calculated

Economic damages

Money already spent and money that will be spent: emergency treatment, surgery, hospitalization, rehabilitation, medication, assistive equipment, home modification, attendant care, lost wages, and lost future earning capacity. In a catastrophic case these are proved with a life care plan and an economist, not with a spreadsheet of receipts.

Non-economic damages

Pain, suffering, disfigurement, disability, and the loss of the things you used to be able to do. Missouri does not cap these in a motor vehicle case.

Punitive damages

Available where the conduct meets the statutory standard: clear and convincing evidence of intentional harm without just cause, or deliberate and flagrant disregard for the safety of others, with leave of court required to plead them (RSMo 510.261). Truck cases reach this bar more often than car cases, because logs, maintenance files and drug test records can show a company that knew and kept running anyway. Missouri's punitive damages cap at RSMo 510.265 has been held unconstitutional as applied to common law claims, but it has not been repealed, so expect the defense to raise it.

Wrongful death damages

Missouri allows the statutory class to recover the pecuniary losses suffered by reason of the death, funeral expenses, and the reasonable value of the services, consortium, companionship, comfort, instruction, guidance, counsel, training and support the deceased provided (RSMo 537.090). The claim also carries the damages the deceased suffered between the injury and the death, which includes medical expenses and conscious pain and suffering, often the largest single element in a fatal semi crash. A jury may also consider the aggravating circumstances attending the death, which is how a carrier that knowingly kept an unsafe truck on the road is punished in a death case. One limit to be clear about: Missouri does not allow recovery for grief and bereavement itself.

What we actually do

• Get a preservation letter out to the carrier and its insurer while the short retention windows are still open
• Pull the crash report from the right agency, whether that is the Highway Patrol or KCPD
• Identify every party in the chain: driver, carrier, tractor owner, trailer owner, broker, shipper, loader, maintenance contractor
• Demand the driver qualification file, the logs and ELD data, the maintenance and inspection records, and the post-crash test results
• Inspect the crash site and the vehicles
• Find every layer of coverage, not just the first policy that answers the phone
• Build the medical evidence, including future care and lost earning capacity
• Handle the adjusters, so you do not have to
