Driver fatigue is one of the most underreported — and most deadly — contributing factors in commercial truck accidents across Missouri. A fatigued truck driver behind the wheel of an 80,000-pound semi is not just a tired person. Reaction time slows, judgment fails, and in the worst cases, the driver falls asleep entirely. When that happens at highway speed on I-70 or US-63 near Columbia, the results are catastrophic for everyone in the way.
Drowsy driving among fatigued truck drivers dramatically increases the risk of crashes. Research consistently shows that a fatigued driver behind the wheel has impairment levels comparable to someone at or above the legal limit for alcohol — yet there is no roadside test for fatigue, which means fatigued driving often goes undetected at the scene. For truck accident victims, this makes the evidence inside the truck's systems more important than anything else.
If you were hurt in a truck accident and suspect driver fatigue played a role, the evidence that proves it exists — but it disappears fast. Bur Oak Injury Law handles truck accident cases throughout central Missouri. No fee unless we win. Call (573) 499-0200 for a free consultation.
Why Driver Fatigue Is So Dangerous in Commercial Trucks
Commercial truck drivers spend long hours on the road, often under pressure from trucking companies and dispatchers to meet tight delivery schedules. The trucking industry runs on tight margins and tight timelines — and that pressure pushes fatigued drivers to push past their safe limits. A drowsy driver operating a commercial vehicle cannot stop as quickly, cannot react to road hazards, and cannot maintain lane position the way a rested driver can.
Research from the National Transportation Safety Board has identified fatigue as a major contributing factor in a significant percentage of large truck crashes. Fatigued driving is especially difficult to detect because it is invisible at the scene — unlike drunk driving, there is no test, no obvious physical sign, and no immediate evidence. The proof is hidden in data: the hours the driver worked, the miles they logged, and whether they violated the federal regulations designed to keep tired commercial drivers off the road.
Federal Hours of Service Rules for Commercial Drivers
The Federal Motor Carrier Safety Administration (FMCSA) sets hours of service regulations that govern how long commercial drivers can operate without rest. Under these service regulations, a truck driver may drive no more than 11 hours after 10 consecutive hours off duty, and cannot drive beyond the 14th hour after coming on duty regardless of breaks taken. Drivers are also limited to 60 or 70 hours on duty over seven or eight days, depending on their schedule.
These federal regulations exist specifically because the research is clear: driver fatigue increases crash risk sharply after certain consecutive hours of driving. Violating the hours of service rules — driving beyond the legal limit, skipping required rest breaks, or falsifying logs — is direct evidence of negligence. In many truck driver fatigue accident cases, that is exactly what happened.
Electronic Logging Devices and Your Case
Since December 2017, federal regulations have required most commercial truck drivers to use electronic logging devices — known as ELDs — to automatically record their hours of service. Unlike paper logbooks, which drivers could manipulate to conceal fatigue, electronic logging devices create a tamper-resistant, time-stamped record of when the truck was moving and for how long.
After a truck accident, ELD data is among the first evidence we request. It can show whether the driver exceeded their legal driving hours, skipped required rest periods, or had been behind the wheel for consecutive hours well beyond what safety rules allow. Trucking companies know this data is damaging — which is why it must be preserved immediately after a crash through a formal legal hold letter sent to the company before data is overwritten or the vehicle is repaired.

The Truck Driver
A fatigued driver who chooses to keep driving — knowing they are exhausted — has made a negligent decision. Personal responsibility includes recognizing when rest periods are necessary and pulling over rather than continuing past the point of safe driving. Medical conditions such as sleep apnea, which dramatically increase fatigue risk, also create individual responsibility when a driver fails to disclose or treat the condition before getting behind the wheel of a commercial vehicle.
The Trucking Company
Trucking companies bear substantial responsibility for the conduct of their commercial drivers. Under the legal doctrine of respondeat superior, trucking companies are directly liable for the negligent acts of their employed drivers while on the job. Beyond vicarious liability, a company that set a delivery schedule that made hours of service compliance impossible, pressured a driver to skip rest breaks, or failed to monitor ELD data for violations bears independent liability for the resulting crash.
The insurance company for the trucking company will typically move quickly after a crash to limit exposure — sometimes contacting injured parties within hours. These early conversations are designed to minimize what the insurer pays, not to fairly compensate you. Having legal representation in place before speaking with any insurance adjuster is one of the most important steps you can take.
Evidence in a Truck Driver Fatigue Case
Building a truck driver fatigue accidents case requires moving fast. Key evidence includes ELD records and driver logs, dispatch communications and delivery schedules, cell phone records showing driver communications while driving, witness testimony from other motorists who observed the truck's behavior before the crash, and black box data — the truck's event data recorder — which captures speed, braking, and throttle position in the seconds before impact.
Our firm sends a spoliation letter to the trucking company immediately after being retained, demanding preservation of all this data. Without a formal legal hold in place, evidence can be overwritten or destroyed within days — leaving you without the proof needed to establish that fatigue caused your crash. Fatigue-related accidents are only proven through data, and that data has a short shelf life.
Injuries in Fatigued Truck Driving Accidents
Fatigue-related accidents often involve catastrophic injuries because a driver who has fallen asleep provides no pre-impact braking. When a fully loaded commercial truck strikes a passenger vehicle at highway speed with no warning and no braking, the force of impact is devastating. Victims of truck driver fatigue accidents commonly suffer traumatic brain injuries, spinal cord damage and paralysis, multiple fractures, internal organ injuries, and severe burns and lacerations. In the most serious cases, fatigued driving results in wrongful death.
The size and weight of commercial vehicles means even a lower-speed impact can cause injuries that require years of treatment and rehabilitation. Damages in these cases include medical expenses, lost income, future earning capacity, pain and suffering, and in cases involving reckless disregard for safety rules, potentially punitive damages.

Steps to Take After a Truck Accident in Columbia, Missouri
The steps you take immediately after a fatigued driving truck crash directly shape the strength of your legal claim.
- Seek medical attention immediately — even if you feel fine. Adrenaline masks serious injuries including internal bleeding and traumatic brain injuries, and a gap in treatment will be used against your claim.
- Call 911 and remain at the scene until law enforcement documents the crash, the vehicles involved, and the driver's condition and behavior.
- Document everything you can — photograph all vehicles, road conditions, skid marks (or their absence), the truck's DOT number, license plate, and the trucking company's name.
- Collect witness contact information from anyone who saw the crash or observed the truck's behavior — erratic lane changes or inconsistent speed — before impact.
- Do not give a recorded statement to the trucking company's insurance adjusters without first speaking to a truck accident attorney. Anything you say will be used to minimize your claim.
- Contact Bur Oak Injury Law immediately at (573) 499-0200. Sending a spoliation letter to preserve ELD data, black box records, and driver logs is often the single most time-critical action in the entire case.
