Proving Fatigue in an Hours of Service Violation Truck Crash
Truck driver fatigue is one of the leading causes of devastating highway collisions. To combat this issue, the federal government enforces strict regulations limiting how many consecutive hours a commercial motorist can drive without taking a rest break. These regulations are known as the Hours of Service (HOS) rules.
Unfortunately, because trucking companies pay drivers by the mile rather than by the hour, motorists are financially incentivized to violate these limits. An hours of service violation truck crash is a direct result of corporate greed overriding public safety guidelines.
Under federal HOS rules, a commercial property-carrying driver is allowed to drive a maximum of 11 hours after 10 consecutive hours off duty. Additionally, they cannot drive past the 14th consecutive hour of being on duty, and they must take a 30-minute break after 8 hours of driving.
How Attorneys Prove HOS Violations
Commercial drivers are legally required to log their status using Electronic Logging Devices (ELDs) directly integrated into the truck's engine. To prove the driver was operating illegally, your lawyer will look for several key pieces of digital evidence:
- ELD Data Audits: We will cross-reference the ELD log files with GPS tracking data, toll booth receipts, and fuel purchases. Drivers who try to fake their logs are easily caught when a fuel receipt shows they were active 100 miles away from their logged rest location.
- Black Box Telematics: The truck's engine computer records the exact ignition times, speed history, and movement patterns. This data provides an undeniable timeline of when the driver was actually operating the vehicle.
- Coercion Records: We will investigate the communication history between the driver and their dispatcher. If the dispatcher threatened to fire the driver unless they delivered a load on a timeline that required violating HOS rules, the trucking company faces severe punitive liability.
The Danger of Fatigued Driving
Scientific studies show that driving after being awake for 18 consecutive hours is equivalent to operating a vehicle with a blood alcohol concentration (BAC) of 0.05%. Driving after 24 hours of wakefulness is equivalent to a 0.10% BAC—well over the legal limit. A fatigued truck driver has slow reaction times and can easily fall asleep, causing high-speed rear-end collisions without ever applying the brakes.
