Fatigue is one of the most dangerous — and most preventable — causes of truck crashes. To combat it, federal law strictly limits how long commercial drivers can be on the road. When a trucking company pushes a driver past those limits, the records can become powerful proof of negligence. Here’s how hours-of-service rules and driver fatigue affect a Michigan truck accident case.
Why fatigue is so dangerous
A drowsy driver behind the wheel of an 80,000-pound truck is a serious hazard. Fatigue slows reaction time, impairs judgment, and can cause micro-sleeps — brief lapses in attention that, at highway speed, cover the length of a football field. Studies have long recognized that fatigued driving can be as impairing as driving under the influence.
What the hours-of-service rules require
The FMCSA’s hours-of-service (HOS) regulations set limits designed to keep tired drivers off the road. In general terms, for property-carrying drivers they include:
- An 11-hour driving limit after 10 consecutive hours off duty.
- A 14-hour on-duty window within which that driving must occur.
- A required 30-minute break after a set period of driving.
- Weekly limits — generally 60 hours in 7 days or 70 hours in 8 days.
- A requirement to track hours with an electronic logging device (ELD).
These rules are part of the broader body of FMCSA regulations that govern trucking.
How companies pressure drivers to break them
Drivers are often paid by the mile and pushed to meet tight delivery deadlines, which creates pressure to keep driving past safe limits or to falsify logs. When a company’s scheduling or incentives effectively force violations, the company — not just the driver — can bear responsibility.
How logs and ELD data prove violations
The ELD and driver logs create a record of when a driver was on the road. A lawyer can obtain and analyze this data — and cross-check it against fuel receipts, GPS, toll records, and delivery timestamps — to reveal whether the driver exceeded the limits or falsified their hours. This is exactly the kind of evidence that can be lost if not preserved quickly.
Falsified logs
Despite ELDs, some drivers and carriers still manipulate records. Inconsistencies between the logs and other records — a fuel purchase or delivery that couldn’t have happened within the logged hours — can expose falsification, which is compelling evidence of both fatigue and a willingness to break the rules.
How fatigue proves negligence in your case
If the evidence shows the driver was over their hours or fatigued, it helps establish that the driver — and often the company that dispatched them — breached the duty to operate safely. Combined with the crash facts, that can be central to proving liability and to the value of your claim.
Fatigue and Michigan No-Fault
As with any Michigan truck crash, your own PIP benefits pay medical bills and wage loss regardless of fault, while the fatigue evidence supports your separate liability claim against the at-fault trucking company for pain and suffering and losses beyond PIP.
Frequently asked questions
How would we know if the driver was fatigued? Through the ELD and logs, cross-checked against other records — a lawyer obtains and analyzes them.
Can the company be liable for the driver’s fatigue? Yes, if its scheduling, pay, or pressure contributed to the violation.
What if the logs were falsified? Exposing falsification can be powerful evidence of negligence.
