Driver Fatigue and Hours-of-Service Violations in Truck Accident Litigation

Denning Law Firm, LLC Oct. 5, 2026

Driver fatigue is a serious safety concern when commercial trucks share the road with passenger vehicles. Long shifts, overnight driving, tight delivery schedules, and inadequate rest can reduce a driver's ability to respond safely to changing traffic conditions. Federal hours-of-service regulations address these risks by restricting driving time and requiring rest periods.

People injured in fatigue-related crashes can face medical expenses, lost income, physical pain, and lengthy recoveries. Determining what happened often requires reviewing driving logs, dispatch communications, vehicle data, and company records.

At the Denning Law Firm, LLC, we can help you assess liability and pursue your claim to seek fair compensation and protect your rights. Our firm serves clients throughout the Kansas City metro area in both Kansas and Missouri. Contact our truck accident attorneys today to discuss your case and explore your legal options.

Federal Hours-of-Service Rules for Commercial Drivers

Under the hours-of-service rules of the Federal Motor Carrier Safety Administration (FMCSA), property-carrying drivers generally can drive for up to 11 hours after having 10 consecutive hours off duty. They cannot drive beyond the 14th consecutive hour after coming on duty, subject to applicable exceptions. Qualifying drivers must also take a 30-minute break after eight cumulative hours of driving without a qualifying interruption.

These limits help address fatigue during demanding routes. Following a crash, we can compare electronic logs with dispatch records and delivery schedules to determine whether a driver exceeded driving limits or missed required breaks. Evidence that a trucking company encouraged unrealistic schedules can also warrant investigation.

Recognizing Driver Fatigue on the Highway

An exhausted truck driver may drift between lanes, miss traffic signals, follow vehicles too closely, or react slowly to stopped traffic. In severe cases, the driver may fall asleep at the wheel. However, similar behavior can have other causes, so investigators must examine the surrounding evidence.

These warning signs are important because fatigue isn't always obvious from the collision scene. Witness statements and camera footage can document driving behavior before impact. Work schedules, overnight routes, and prior rest periods may reveal whether exhaustion contributed to the crash. Our team can examine these details together rather than relying on a single warning sign.

Electronic Logging Devices and Logbook Falsification

Electronic logging devices automatically record a driver's driving time and help record hours-of-service information for covered commercial drivers. Their records can establish when a truck was driven, but entries and duty-status information still require scrutiny.

We can compare logs with GPS data, fuel receipts, toll records, inspection reports, and delivery documents. A recorded rest period that conflicts with evidence of vehicle movement may justify further inquiry. Comparing multiple sources can help reconstruct the driver's hours and identify inaccurate entries without assuming that every discrepancy proves falsification.

Investigating Causes of Commercial Crashes

Fatigue is one possible contributing factor in a Kansas City truck collision. Distraction, speeding, impairment, equipment problems, and unsafe company practices may also contribute. An investigation should consider these possibilities instead of treating an hours-of-service violation as a complete explanation.

According to the FMCSA, employers must conduct post-accident drug and alcohol testing of covered surviving commercial drivers following qualifying crashes, including crashes involving a fatality. Testing requirements depend on the circumstances of the crash.

Evidence may also include:

  • Vehicle data showing speed, braking, and other activity near impact.

  • Dispatch messages and delivery schedules documenting instructions or time pressure.

  • Maintenance, GPS, shipping, and inspection records establishing the truck's condition and movements.

Preserving these materials promptly can help us build a timeline and investigate potential responsibility.

Proving Liability When Hours-of-Service Rules Are Broken

An hours-of-service violation doesn't answer every liability question by itself. Evidence must still connect a driver's conduct or fatigue to the collision. Excessive driving hours may carry greater significance when witnesses also describe lane drifting, delayed braking, or other signs of impaired attention.

A trucking company may also face scrutiny if its scheduling, supervision, or dispatch practices contributed to unsafe operation. Company communications and policies may show what supervisors knew and whether they encouraged drivers to continue without adequate rest.

We can assess driver conduct, company records, and accident-related losses to identify potentially responsible parties. Depending on the evidence and applicable law, compensation may address medical expenses, lost wages, reduced earning capacity, rehabilitation costs, and pain and suffering.
