There were 156,553 large truck accidents in 2023, which caused 4807 fatalities. Given that a fully-loaded semi-truck can weigh as much as 80,000 pounds, it’s no wonder truck accidents are so dangerous. Truck drivers operate large, heavy vehicles that require alertness and quick reaction times to drive safely.
Sleep deprivation impairs these abilities and dramatically increases the risk of truck accidents. This article will examine the impacts of sleep deprivation and fatigue on truck driver performance and truck accident rates.

Causes of Sleep Deprivation in Truck Drivers
There are several factors that contribute to the prevalence of sleep deprivation among truck drivers:
- Irregular Schedules – Truck drivers often work irregular shifts, making it difficult to maintain normal sleep patterns. Overnight driving further disrupts circadian rhythms.
- Time Pressures—Truck drivers face pressure to meet tight delivery windows and drive longer than permitted, which reduces opportunities for adequate rest.
- Inadequate Sleep Environments – Sleeping in a truck cab does not provide an optimal sleep environment. Noise, vibrations, and uncomfortable bunks impair sleep quality.
- Undiagnosed Sleep Disorders – Sleep apnea and other disorders are more common among truck drivers, and those conditions lead to poor sleep. Around 30 million people suffer from sleep apnea, but only 6 million have a medical diagnosis.
These sleep-related issues, along with fatigue, can contribute to truck accidents, which may result in serious injuries or fatalities. In such cases, it is important to contact truck accident attorneys who can help victims pursue compensation for medical expenses, lost wages, and pain and suffering, ensuring that negligent parties are held responsible.
Impacts on Driving Ability
As experienced truck accident lawyers know, sleep deprivation has been conclusively shown to degrade driving performance and alertness:
- Slower Reaction Times—Drowsy drivers take longer to react to road hazards and unexpected events, which increases the chance of accidents.
- Impaired Judgment – Fatigued drivers misjudge distances, speeds, and travel paths. Their decision-making skills are also impaired.
- Reduced Alertness – Sleepy drivers experience lapses in attention and microsleeps where they nod off for a few seconds. This causes them to miss stop signs, traffic signals, and other cues.
- Mood Changes – Sleep deprivation increases irritability and moodiness, which may lead to reckless or aggressive driving.
Link to Truck Accidents
Research shows that sleep deprivation is a major contributor in truck accidents:
- The FMCSA estimates 13% of commercial truck crashes are due to fatigued driving. This amounts to over 4,000 fatigue-related truck crashes annually.
- Drowsy driving is a suspected factor in the majority of single-vehicle truck crashes where the truck drives off the road.
- Truck drivers with severe sleep apnea have a 5 times higher crash rate compared to healthy drivers.
Can Technology Help?
Driver Fatigue Monitoring Systems
These in-vehicle systems use cameras and sensors to monitor a driver’s eyes, head position, steering wheel movements, etc., and to detect signs of drowsiness. The system alerts the driver if they show signs of fatigue, prompting them to stop and rest.
Electronic Logging Devices (ELDs)
ELDs automatically track a truck’s driving time and provide records of hours driven, stops taken, and rest periods. This helps enforce compliance with legal limits on driving hours between mandatory breaks and discourages truckers from exceeding these limits and becoming dangerously fatigued.
Smart Rest Area Technology
Rest areas are implementing smart technology to promote better sleep for truckers. Reservable parking spots allow drivers to plan stops ahead of time. Lighting systems mimic natural sleep/wake cycles. Fitness centers and healthy food provide energy.
Technology makes drivers and fleet managers more accountable in the fight against fatigued trucking. Devices that monitor driver alertness in real-time and track compliance with safety regulations are major advancements to curb this risky behavior and save lives.
Reducing sleep-deprived driving provides the best opportunity to prevent a significant number of truck accidents.
