A fully loaded commercial truck can weigh 20 to 30 times more than a passenger car. Where a passenger vehicle traveling at highway speed might come to a stop in about 300 feet, a large truck can need the length of two football fields or more.
Every second matters, and a driver’s ability to perceive a hazard and react quickly is often the difference between a safe trip and a serious accident. Fatigue is one of the things that undermines these abilities. A drowsy driver reacts more slowly, pays less attention to the road, and makes poorer judgment calls about speed, following distance, and changing road conditions.

What Causes Truck Driver Fatigue?
Several factors common to the trucking industry contribute to driver fatigue:
Long hours behind the wheel
Federal hours-of-service regulations permit driving shifts of up to 11 hours, and extended periods of continuous driving reduce alertness even when a driver remains within legal limits. In other situations, drivers may surpass these limits, which can lead to driving while fatigued.
Overnight or irregular shifts
Driving during overnight hours can confuse the body’s circadian rhythm, the period when alertness is naturally at its lowest. This means even when a driver gets enough sleep during the day, they may be unusually fatigued when driving at night.
Pressure to meet delivery deadlines
Demanding schedules and mileage-based compensation can lead drivers to continue operating when rest is needed.
Inadequate rest between shifts
Off-duty time spent loading, unloading, or waiting at facilities does not provide the restorative sleep required for safe driving. If appropriate rest isn’t taken, an accident becomes more likely once the driver starts operating the vehicle again.
Driving after multiple days of poor sleep
Insufficient sleep accumulates over consecutive days, which isn’t uncommon for truck drivers. This can result in impairment that a single rest break does not resolve. Fatigue is not always apparent from the outside.
There is no roadside test for drowsiness, and a driver may show no visible signs of impairment at the scene of a crash. This can make fatigue-related collisions more difficult to investigate.
How Is Truck Driver Fatigue Proven After an Accident?
Because there is no chemical test for fatigue, these cases are typically built on documentation that reconstructs the driver’s schedule, activity, and condition in the hours and days before the crash. Relevant evidence may include:
- Electronic logging device (ELD) data, which records driving time, on-duty status, and rest periods
- Driver logs, which can be compared against ELD data and other records for inconsistencies
- Delivery schedules, which may show whether a route could realistically be completed within legal hours-of-service limits
- Cell phone records, which can indicate activity during periods logged as rest
- Fuel and toll receipts, which establish a timeline of the truck’s location and movement
- Dispatch communications, which may reveal pressure to meet deadlines or continue driving despite fatigue
- Surveillance or dashcam footage, which can document erratic driving or the driver’s condition
- Medical records involving sleep disorders, where a diagnosed or undiagnosed condition is relevant to the driver’s alertness
Preserving this evidence early is critical. Federal regulations require motor carriers to retain certain records only for limited periods, and ELD data, dashcam footage, and dispatch communications may be overwritten or deleted in the ordinary course of business.
A timely preservation letter puts the trucking company on notice of its legal obligation to retain this material. In these cases, one of the best things you can do is to reach out to an experienced personal injury lawyer right away so they can help you get the evidence you need to prove your case.
