Truck Accident Causes
Injured in a Truck Accident?
Key Takeaways
- A property-carrying truck driver may drive no more than 11 hours within a 14-hour window that begins after 10 consecutive hours off duty, under 49 CFR 395.3.
- Texting and hand-held phone use (49 CFR 392.80 and 392.82), inspection and maintenance (Part 396), and cargo securement (Part 393) each leave a federal record trail after a truck crash.
- Driver qualification rules in 49 CFR Part 391 and drug testing and Clearinghouse checks in Part 382 set the screening a trucking company must do before a driver takes the wheel.
Common Truck Accident Causes
Truck crashes in Kentucky and nationwide commonly trace back to driver fatigue, distracted driving, FMCSA hours-of-service violations, overloaded or improperly secured cargo, brake failure, speeding, and negligent hiring by motor carriers. Underrides, tire blowouts, and unsecured loads cause preventable crashes as well.
Federal regulation creates a paper trail behind most of these causes, so a truck crash investigation looks different from a standard car crash investigation. Electronic logging device records, maintenance files, driver qualification files, and black box data preserved after a crash can establish each cause.
Driver Fatigue and FMCSA Hours-of-Service Violations
Fatigue slows reaction time the way alcohol does: according to the CDC’s National Institute for Occupational Safety and Health, impairment after 17 consecutive hours awake is equivalent to a blood alcohol content of .05. The FMCSA hours-of-service regulations limit driving time to manage that risk. Under 49 CFR 395.3, a property-carrying driver may not drive without first taking 10 consecutive hours off duty, may not drive after 14 consecutive hours on duty, and may drive a total of 11 hours within that window. ELD records and logbooks document violations of these limits, and a violation can be evidence of negligence.
Federal law allows a gross vehicle weight of up to 80,000 pounds on the Interstate System under 23 CFR 658.17, so a fraction of a second of lost reaction time at highway speed on I-65 or I-75 can decide whether a crash happens. When a carrier’s dispatch records show a driver was pushed beyond legal limits, that pressure becomes part of the negligence case against the carrier as well as the driver.
Federal Rules on Distraction, Brakes, and Cargo
Three sets of federal regulations govern common driver-conduct and equipment failures behind truck crashes:
Negligent Hiring, Training, and Carrier Oversight
Motor carriers have an independent duty to screen, hire, train, and supervise their drivers. Under 49 CFR Part 391, a carrier must keep a driver qualification file for each driver, including motor vehicle records from each licensing authority (49 CFR 391.51). Under 49 CFR 382.301, a driver must pass a pre-employment controlled substances test, and under 49 CFR 382.701, the carrier must query the FMCSA Drug and Alcohol Clearinghouse before the driver performs safety-sensitive functions. When a carrier hires a driver with a history of violations, failed drug tests, or disqualifying medical conditions and that driver causes a crash, the carrier can face a negligent hiring claim, and keeping a driver with a documented violation history on the road without added oversight can support a negligent retention claim.
The FMCSA Safety Measurement System (SMS) ranks carriers by percentile in safety categories using roadside inspection, crash, and investigation data. An SMS percentile is not a safety rating, which FMCSA issues only after an investigation, but a carrier’s record of out-of-service violations and crashes can show what the company knew about the risk its fleet presented.
Building a Multi-Cause Truck Accident Case
Serious truck crashes frequently involve more than one contributing cause, such as a fatigued driver operating a poorly maintained truck under pressure to meet a delivery deadline set by dispatch. Investigating each potential cause separately, instead of settling on the first apparent explanation, often reveals the fuller picture of what happened and who bears responsibility.
Injured in a Crash With a Commercial Truck?
Hours-of-service logs, ELD data, maintenance files, and driver qualification files show why a truck crashed, and the trucking company controls most of them. A claim built on every cause names every company behind the truck.

Frequently Asked Questions
1How is driver fatigue proven in a truck accident case?+
Electronic logging device data, dispatch records, and the driver’s hours-of-service logs are reviewed together to establish whether the driver exceeded the driving limits in FMCSA hours-of-service regulations, including the 11-hour driving limit in 49 CFR 395.3.
2Can a trucking company be held liable for a crash caused by overloaded cargo?+
Yes. Cargo securement is governed by 49 CFR Part 393, and 49 CFR 392.9 bars a carrier from requiring or permitting a driver to operate a truck whose cargo is not properly distributed and secured.
3What records does an attorney request after a truck crash?+
Driver qualification files, hours-of-service logs, ELD data, maintenance and inspection records, drug and alcohol testing records, and the trucking company’s history in the FMCSA Safety Measurement System are among the records commonly requested.
4Does brake failure create liability for the trucking company?+
It can. 49 CFR 396.3 requires every motor carrier to systematically inspect, repair, and maintain its vehicles, so a brake failure traced to skipped inspections or an unrepaired defect can make the company responsible alongside or instead of the driver.
5What is negligent hiring in a trucking case?+
Negligent hiring is a trucking company placing a driver behind the wheel despite red flags such as prior safety violations, failed drug tests, or disqualifying medical conditions that the screening required by 49 CFR Part 391 and Part 382 should have caught.
