Driver Fatigue Truck Accident Lawyer
Driver fatigue is a leading cause of serious truck crashes. Federal hours-of-service rules limit drivers to 11 driving hours in a 14-hour window, and electronic logging devices (ELDs) record compliance. When logs show violations — or the carrier pressured drivers to break them — both driver and trucking company can be held liable.
Key Takeaways
- FMCSA research links fatigue to roughly 13% of serious truck crashes.
- Hours-of-service rules (49 CFR Part 395) cap driving at 11 hours after 10 consecutive hours off duty.
- ELD data, delivery schedules, and fuel receipts can prove a driver was over hours.
- Carriers that set impossible schedules share liability with the driver.
Why fatigued truck drivers cause catastrophic crashes
A drowsy driver's reaction time, judgment, and lane control degrade in ways that mirror alcohol impairment — the CDC equates 20 hours awake with a 0.08% blood alcohol level. Behind the wheel of an 80,000-pound tractor-trailer moving at highway speed, those lost seconds of reaction time translate into rear-end collisions, lane-departure crashes, and drift-off-road wrecks that smaller vehicles rarely survive.
Fatigue in trucking is rarely a personal failing alone. Tight delivery windows, pay-per-mile compensation, and dispatcher pressure push drivers to keep rolling past legal limits. That is exactly why federal law treats hours-of-service violations so seriously — and why juries do too.
How lawyers prove a fatigue case
Since the 2017 ELD mandate, nearly every interstate truck records driving time electronically. Your legal team compares ELD logs against GPS pings, toll records, fuel receipts, bills of lading, and delivery timestamps to expose falsified logs or off-the-books driving. The truck's engine control module (its 'black box') adds speed and braking data from the moments before impact.
A spoliation letter must go out immediately — carriers are only required to retain some records for six months, and ELD data can be overwritten. Early attorney involvement is often the difference between a provable fatigue case and a driver's word against yours.

Frequently Asked Questions
What are the hours-of-service limits for truck drivers?+
Property-carrying drivers may drive up to 11 hours after 10 consecutive hours off duty, within a 14-hour on-duty window, and no more than 60 hours in 7 days or 70 hours in 8 days (49 CFR Part 395).
Can the trucking company be sued for a fatigued-driving crash?+
Yes. Carriers are vicariously liable for their drivers and can be directly liable for negligent scheduling, pressuring drivers to violate hours-of-service rules, or ignoring falsified logs.
How do you prove the driver was fatigued?+
Through ELD logs, black box data, GPS and toll records, delivery schedules, receipts, the driver's phone records, and post-crash inspection reports — often showing the driver was over legal hours or had falsified logs.
