Commercial truck drivers are responsible for transporting billions of tons of freight across the United States every year. While most drivers operate their vehicles safely and professionally, fatigue remains one of the greatest safety risks in the trucking industry. Long hours behind the wheel, overnight driving, irregular sleep schedules, traffic congestion, and demanding delivery deadlines can all contribute to dangerous levels of driver fatigue.
Unlike speeding or distracted driving, fatigue is often invisible. A truck driver may not realize how impaired they have become until it is too late. Even a few seconds of microsleep while operating an 80,000-pound tractor-trailer can lead to catastrophic consequences, including serious truck accidents.
At John J. Malm & Associates, we have represented victims of serious truck accidents throughout Illinois. Understanding how fatigue affects commercial truck drivers can help accident victims recognize when negligence may have contributed to a crash and why a thorough investigation is critical.
Why Fatigue Is a Serious Problem in the Trucking Industry
Commercial truck drivers often spend 10 or more hours driving in a single day while covering hundreds of miles. Although federal regulations limit the number of hours drivers can operate, fatigue remains a common issue because drivers may experience poor sleep, changing work schedules, traffic delays, or pressure to meet delivery deadlines.
According to the Federal Motor Carrier Safety Administration (FMCSA), approximately 168,000 people were injured and more than 5,000 people were killed in crashes involving large trucks in the United States in 2022. While fatigue is only one of many contributing factors, the FMCSA and the National Transportation Safety Board (NTSB) have consistently identified driver fatigue as a major safety concern in commercial trucking.
Research from the National Highway Traffic Safety Administration (NHTSA) also shows that drowsy driving contributes to thousands of crashes each year across all vehicle types, many of which likely go unreported because fatigue is difficult to identify after an accident.
How Fatigue Affects Truck Drivers
Sleep deprivation affects the brain in ways similar to alcohol impairment. Fatigued drivers may experience:
- Slower reaction times
- Reduced concentration
- Poor decision-making
- Difficulty maintaining lane position
- Delayed braking
- Impaired judgment
- Reduced situational awareness
- Memory lapses
- Difficulty processing changing traffic conditions
In severe cases, drivers may experience microsleep, brief episodes lasting only a few seconds during which they are effectively asleep without realizing it. At highway speeds, a truck traveling 70 miles per hour can travel more than 100 feet every second. A five-second microsleep means the truck may travel the length of a football field without the driver actively controlling the vehicle.
Common Causes of Driver Fatigue
Numerous factors contribute to fatigue among commercial truck drivers. Some of the most common include:
- Long driving hours
- Overnight driving
- Irregular work schedules
- Sleep disorders such as obstructive sleep apnea
- Tight delivery deadlines
- Poor sleep quality
- Extended loading and unloading delays
- Heavy traffic
- Stress
- Poor nutrition
- Certain medications
Even drivers who comply with federal Hours-of-Service regulations may become dangerously fatigued if they are not getting adequate, restorative sleep.
Federal Hours-of-Service Rules
To reduce fatigue-related crashes, the FMCSA has established Hours-of-Service (HOS) regulations governing commercial truck drivers. Generally, property-carrying commercial drivers may:
- Drive a maximum of 11 hours after 10 consecutive hours off duty.
- Not drive beyond the 14th consecutive hour after coming on duty.
- Take required rest breaks after specified driving periods.
- Comply with weekly driving limits of 60 or 70 hours depending on the carrier’s operating schedule.
These rules are intended to reduce fatigue, but violations still occur. Some drivers or trucking companies may falsify electronic logs, pressure drivers to exceed legal limits, or fail to monitor compliance.
Warning Signs of Fatigue
Fatigue rarely occurs without warning. Common signs include:
- Frequent yawning
- Heavy eyelids
- Drifting between lanes
- Missing traffic signs
- Difficulty remembering recent miles traveled
- Delayed reactions
- Head nodding
- Trouble maintaining a constant speed
- Feeling restless or irritable
When these symptoms appear, the safest course of action is to stop driving and rest.
Fatigue Can Be as Dangerous as Alcohol
Numerous scientific studies have found that prolonged wakefulness significantly impairs driving performance. Researchers have found that remaining awake for approximately:
- 18 hours can produce impairment similar to a blood alcohol concentration (BAC) of approximately 0.05%.
- 24 hours without sleep may impair performance similarly to a BAC of approximately 0.10%, above the legal limit for most passenger vehicle drivers.
For commercial drivers, the legal BAC limit is 0.04%, reflecting the heightened responsibility associated with operating large commercial vehicles. Although fatigue and alcohol are different forms of impairment, both reduce reaction time, judgment, attention, and coordination.
Fatigue-Related Truck Accidents Often Share Common Characteristics
Many fatigue-related truck crashes involve similar patterns. These accidents frequently occur:
- During overnight hours
- Between midnight and 6:00 a.m.
- In the early afternoon
- On long stretches of highway
- After extended periods of continuous driving
- Near the end of a driver’s shift
Fatigued drivers may fail to brake before impact, resulting in particularly severe rear-end collisions or roadway departure crashes.
Sleep Apnea and Commercial Truck Drivers
Sleep apnea is another significant concern within the trucking industry. Obstructive sleep apnea causes repeated interruptions in breathing during sleep, preventing restorative rest even when a person spends sufficient time in bed. Symptoms include:
- Loud snoring
- Daytime sleepiness
- Morning headaches
- Difficulty concentrating
- Falling asleep unexpectedly
Untreated sleep apnea substantially increases the risk of fatigue-related crashes. Trucking companies have a responsibility to ensure drivers who have been diagnosed with sleep apnea comply with prescribed treatment before operating commercial vehicles.
How Fatigue Is Investigated After a Truck Accident
Unlike alcohol impairment, fatigue cannot be confirmed with a blood test. Instead, investigators examine numerous forms of evidence, including:
- Electronic logging device (ELD) records
- Driver qualification files
- Dispatch communications
- GPS records
- Fuel receipts
- Toll records
- Cell phone records
- Surveillance footage
- Witness statements
- Driver schedules
- Delivery deadlines
- Rest break documentation
This evidence may reveal whether the driver violated Hours-of-Service regulations or had been awake for an unsafe period before the collision.
Can Trucking Companies Be Liable?
Yes. Trucking companies have legal responsibilities that extend beyond hiring qualified drivers. Potential negligence may include:
- Encouraging Hours-of-Service violations
- Unrealistic delivery schedules
- Poor supervision
- Failure to monitor electronic logs
- Negligent hiring
- Negligent retention
- Failure to investigate prior violations
- Inadequate fatigue management policies
When company practices contribute to fatigued driving, the carrier may share liability for resulting injuries.
Fatigue Is Often Combined With Other Safety Violations
Fatigue rarely exists in isolation. Investigations frequently uncover additional problems, including:
- Speeding
- Distracted driving
- Improper maintenance
- Brake defects
- Overloaded trailers
- Drug or alcohol use
- Inadequate driver training
- Improper cargo securement
A comprehensive investigation often identifies multiple contributing causes of a serious truck accident.
“Fatigue is one of the most underestimated dangers in the trucking industry. A driver who has been awake for too long may have reaction times and judgment comparable to an impaired driver. When trucking companies ignore fatigue or pressure drivers to stay on the road beyond safe limits, innocent motorists can suffer life-changing injuries. Our firm works to uncover the evidence needed to hold negligent drivers and trucking companies accountable.” — John J. Malm, Naperville semi crash lawyer
Why You Need an Experienced Illinois Truck Accident Attorney
Fatigue-related truck accident cases require far more than reviewing a police report. An experienced attorney can help obtain critical evidence, including:
- Electronic logging device data
- Driver logbooks
- Black box (ECM) information
- Dispatch communications
- Driver qualification files
- Maintenance records
- Cell phone records
- Surveillance video
- Accident reconstruction analysis
Because trucking companies often begin their own investigations immediately after a crash, accident victims should seek legal representation as soon as possible to preserve important evidence.
Frequently Asked Questions about Trucker Fatigue
What is driver fatigue?
Driver fatigue is a state of physical or mental exhaustion that reduces a driver’s ability to safely operate a vehicle. It can impair reaction time, attention, judgment, and decision-making, increasing the risk of serious crashes.
Can a truck driver be liable if fatigue caused an accident?
Yes. If a truck driver operated a commercial vehicle while dangerously fatigued or violated federal Hours-of-Service regulations, that conduct may support a claim for negligence. Liability depends on the specific facts of the case.
How do investigators determine whether fatigue contributed to a crash?
Investigators review evidence such as electronic logging device records, work schedules, dispatch records, GPS data, witness statements, surveillance footage, and other documentation to determine whether the driver may have been fatigued.
Can the trucking company also be responsible?
Yes. A trucking company may be liable if it encouraged Hours-of-Service violations, failed to monitor driver compliance, imposed unrealistic delivery schedules, or negligently hired or retained an unsafe driver.
What compensation may be available after a fatigue-related truck accident?
Depending on the circumstances, injured victims may recover compensation for medical expenses, lost wages, diminished earning capacity, pain and suffering, disability, rehabilitation costs, and other damages.
How soon should I contact an attorney after a truck accident?
Immediately. Electronic records, logbooks, onboard computer data, and surveillance footage can be lost or overwritten if they are not preserved promptly. Early legal representation can help protect valuable evidence and strengthen your claim.
