OKC Injury Lawyer Explains How Trucker Fatigue Causes Serious Accidents
A fully-loaded semi-truck weighs up to 80,000 pounds. Trucks take twice as long to stop as cars and they cause severe injuries and fatalities when they crash into regular passenger vehicles. When the person behind the wheel of a big rig truck is exhausted, the consequences can be devastating.
Ray Maples, Rilee Harrison, and Christian Zeaman are experienced truck accident lawyers in OKC. Maples Harrison Zeaman PLLC has extensive experience holding truck drivers liable for their reckless driving and Hours of Service violations that have caused our clients harm.
Driver Fatigue and Commercial Trucking
At 65 miles per hour, a truck can travel the length of a football field in about three seconds. If a driver “nods off” even briefly, they can plow into stopped traffic, construction zones, or smaller vehicles without ever touching the brakes.
Fatigue is more than just feeling tired. In the trucking industry, it can mean:
- Slowed reaction times
- Impaired judgment
- Drifting between lanes
- Missing traffic signals
- Delayed braking
- Micro-sleep episodes lasting several seconds
Federal Hours of Service Rules for Truckers
To combat fatigue, the federal government enforces strict Hours of Service laws through the Federal Motor Carrier Safety Administration (FMCSA). These FMCSA Hours of Service (HOS) rules limit how long commercial drivers can operate without rest.
Under current Hours of Service laws, most property-carrying drivers must follow these limits:
- 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 cannot drive beyond the 14th consecutive hour after coming on duty, even if they took breaks.
- 30-minute break requirement: After 8 cumulative hours of driving, a driver must take a 30-minute break.
- 60/70-hour weekly cap: Drivers may not drive after 60 hours on duty in 7 consecutive days or 70 hours in 8 consecutive days.
Using Data to Prove Negligence
Today, most commercial trucks use Electronic Logging Devices (ELDs). These devices automatically record driving time, engine hours, vehicle movement, and miles driven. When the data does not match the driver’s claimed rest periods, it can reveal violations of HOS rules.
In a fatigue-related crash, we immediately seek the following types of information:
- ELD data
- Paper logbooks (if applicable)
- Fuel receipts
- Toll records
- GPS data
- Dispatch communications
- Cell phone records
Trucking companies that knowingly encourage violations of Hours of Service laws may share liability. In some cases, trucking companies set unrealistic delivery schedules that practically require drivers to exceed legal limits. Text messages and internal communications may show drivers being pushed to “make up time” or ignore rest requirements.
Trucking Companies May Be Liable
Under federal trucking regulations, fatigue compliance is a corporate responsibility. Companies must maintain safety management systems, review logs, and ensure drivers are qualified and properly rested.
When they cut corners to increase profits, innocent motorists pay the price. Trucking companies may be found liable for injuries caused by trucker fatigue when they:
- Fail to monitor driver hours
- Ignore prior safety violations
- Hire drivers with a history of fatigue-related incidents
- Pay drivers in a way that encourages excessive hours
Reason to See a Lawyer Right Away
After a crash, trucking companies may deploy rapid response teams to protect their interests. Critical evidence may be lost or destroyed. Black box data can be overwritten. Paper records can be misplaced. Electronic data can be altered or lost.
A truck accident lawyer can start investigating the accident right away and take active steps to protect evidence. Maples Harrison Zeaman PLLC can send a spoliation letter demanding that all evidence is preserved. We work with accident reconstruction professionals and industry specialists to analyze compliance with fatigue standards according to federal trucking regulations.

Frequently Asked Questions
What is truck driver fatigue, and why is it so dangerous?
Truck driver fatigue occurs when a commercial driver operates a vehicle while physically or mentally exhausted. Fatigue can slow reaction times, impair judgment, reduce awareness, and even cause drivers to fall asleep behind the wheel. Fatigue-related truck accidents often result in severe injuries or fatalities due to the size and force of these vehicles.
What causes truck driver fatigue?
Several factors contribute to truck driver fatigue. Long driving hours, tight delivery deadlines, overnight shifts, irregular sleep schedules, and inadequate rest breaks all play a role. Even though federal regulations limit driving hours, some drivers exceed those limits due to pressure from employers or financial incentives tied to mileage.
Are there laws that limit how long truck drivers can drive?
Yes. Federal Hours of Service (HOS) regulations enforced by the Federal Motor Carrier Safety Administration (FMCSA) strictly limit how long commercial drivers can operate without rest. These rules set daily driving limits, mandatory break requirements, and weekly caps on total driving hours. Violations of these rules can be important evidence in a truck accident claim.
How can you prove a truck driver was fatigued at the time of the crash?
Proving fatigue often requires a detailed investigation. Evidence may include electronic logging device (ELD) data, driver logbooks, black box information, dispatch records, fuel receipts, and GPS tracking data. Witness statements, dashcam footage, and accident reconstruction findings may indicate signs of fatigue, such as delayed braking or lane drifting before impact.
Can the trucking company be held responsible for a fatigue-related accident?
Yes. In many cases, liability extends beyond the driver. Trucking companies are responsible for monitoring driver hours, enforcing safety policies, and complying with federal regulations. If a company pressured a driver to exceed legal limits, ignored prior safety violations, or failed to properly supervise operations, it may share responsibility for the crash.
