Truck Driver Fatigue Accident Cases
Studies show that driving after 18–20 hours without sleep impairs judgment and reaction time as much as a blood alcohol level of 0.05–0.10%. Federal hours-of-service rules exist specifically to prevent fatigued truck drivers — violations are direct evidence of negligence.
The Scale of the Problem
The Federal Motor Carrier Safety Administration estimates that driver fatigue is a factor in 13% of all large truck crashes — over 100,000 accidents annually. The FMCSA created the Hours of Service (HOS) regulations specifically to limit the time drivers can be behind the wheel.
Despite these rules, the competitive pressure in the trucking industry — combined with the difficulty of enforcement before Electronic Logging Devices (ELDs) became mandatory — led to widespread violations. Trucking companies and drivers who pushed past legal limits created preventable tragedies.
FMCSA Hours of Service Rules
Current FMCSA HOS regulations for property-carrying drivers include:
11-Hour Driving Limit
A driver may drive a maximum of 11 hours after 10 consecutive hours off duty.
14-Hour On-Duty Limit
A driver may not drive beyond the 14th consecutive hour after coming on duty, following 10 consecutive hours off duty.
Rest Breaks
Drivers must take a 30-minute break after 8 cumulative hours of driving without a 30+ minute break.
60/70-Hour Limit
Drivers may not drive after 60/70 hours on duty in 7/8 consecutive days. A 34-hour restart provision allows resetting the clock.
Electronic Logging Devices (ELDs)
Since December 2017, most commercial trucks are required to use Electronic Logging Devices that automatically record driving time directly from the truck's engine. ELDs:
- → Record exact driving and on-duty hours electronically
- → Are much harder to falsify than paper logs
- → Provide timestamped evidence of HOS violations
- → Can show the driver was operating when fatigued at the time of the crash
An attorney can subpoena ELD data before it is overwritten — typically within 6 months — to build a fatigue case.
Signs of Driver Fatigue in Accident Investigation
- Crash at a time when drowsiness is common (2–6 AM or 1–3 PM)
- No skid marks — fatigued drivers don't brake before falling asleep
- Single-vehicle crash (run off road, striking median)
- ELD or logbook records showing near-limit or over-limit driving hours
- Driver admissions to feeling tired
- Dispatch records showing unrealistic delivery deadlines
- Prior HOS violations in the driver's history
Carrier Liability for Fatigue Crashes
Trucking companies often know — or should know — when drivers are fatigued. They face liability for:
- Setting delivery schedules that cannot be met without HOS violations
- Failure to monitor driver compliance with HOS rules
- Encouraging or pressuring drivers to drive past legal limits
- Ignoring prior HOS violations by the same driver
- Failure to implement fatigue management programs
ELD Data Expires
Electronic logging device data is often overwritten after 6 months. Request a legal hold immediately to preserve this critical evidence.
