FMCSA Regulations

Driver Fatigue: The Most Preventable Cause of Truck Crashes

6 min read May 17, 2026

Driver Fatigue and Truck Accident Liability

Driver fatigue is the leading cause of commercial truck accidents. When a trucking company knowingly allows fatigued drivers to operate vehicles, they are liable for resulting injuries.

FMCSA Fatigue Rules

The FMCSA Hours of Service (HOS) rules exist specifically to prevent driver fatigue:

  • Maximum 11 hours of driving per 14-hour work day
  • Minimum 10 hours off-duty between shifts
  • No more than 60 hours per 7-day period
  • Mandatory rest on the 8th day

Signs of a Fatigued Driver

Accidents involving fatigued drivers typically show:

  • Drifting between lanes
  • Failure to brake or slow down
  • Reduced reaction time
  • Jackknife or rollover patterns

Proving Negligence

Your attorney will obtain:

  • ELD records showing HOS violations
  • Driver logbook entries
  • Company dispatch records
  • Expert analysis of accident mechanics

Settlement Values

Fatigue-related accidents result in substantial settlements because companies are required by federal law to prevent them.
