Hours-of-Service Violations and Truck Crashes
Federal rules limit how long a commercial driver can be behind the wheel before resting. When those limits are ignored, fatigue follows — and the violation itself can become key evidence in your claim.
What the hours-of-service rules do
Federal hours-of-service rules cap how many hours a trucker can drive and work before a required break or off-duty period, and require drivers to log their time. The goal is simple: a driver who has been awake and working too long is a danger to everyone around them.
How violations happen — and get hidden
Pressure to deliver on tight schedules pushes some drivers and companies to exceed the limits, then to fudge the records. Electronic logging devices have made logs harder to falsify, but disputes over accuracy and tampering still arise. A gap between the logs and other records, like fuel and toll receipts, can reveal the truth.
Turning a violation into proof
Establishing an hours-of-service violation usually means comparing the driver's logs against independent evidence and the company's dispatch records. Because those records are controlled by the company and retained only for a limited time, preserving them quickly is essential.

Frequently asked questions
How would I know if the driver was over their hours?
You usually cannot tell at the scene. It comes out later, by obtaining the driver's electronic logs and comparing them against fuel, toll, GPS, and delivery records. That is part of investigating a truck case.
Why do hours-of-service violations matter so much?
Because fatigue is a leading cause of serious truck crashes, and a logged violation is concrete proof of a dangerous choice — far harder for the company to dismiss than a general claim that the driver was tired.
Arizona law — what people ask
How long do I have to file an injury claim in Arizona?
Generally two years. But if a public entity is involved you must serve a formal notice of claim within 180 days and file suit within one year — and Arizona runs a much shorter one-year clock on dog-bite strict-liability claims specifically.
Can I still recover if I was partly at fault in Arizona?
Yes. Arizona applies pure comparative negligence, so fault reduces your recovery rather than ending the claim, and there is no percentage at which it cuts off. Arizona also treats fault questions as belonging to the jury rather than being resolved beforehand.
Does Arizona cap what I can recover?
No — and this sets Arizona apart from most states. Its constitution prohibits laws limiting damages for injury or death, and that applies to medical-malpractice claims too, where most states impose a cap. If you have read that pain and suffering is capped, that is not Arizona law.
What if more than one party was responsible?
Arizona generally applies several liability, so each responsible party answers for its own share rather than the whole judgment. That makes identifying every responsible party early a practical question about what is actually collectible.
The driver who hit me had no insurance. What now?
Your own uninsured or underinsured coverage is the usual route. Arizona also requires insurers to offer that coverage in writing — so if you were told your policy carries none, the underwriting file is worth checking before that answer is accepted.
Will the jury hear that my health insurance paid my bills?
Usually not — Arizona generally follows the collateral source rule. Medical-negligence cases are the statutory exception, where that evidence has been made admissible, which changes how medical damages are presented in those claims specifically.
Injury law in Arizona
Arizona injury law has some features that set it apart from its neighbors.
- Filing deadline: Arizona generally gives you two years from the injury to file, but only 180 days to serve a notice of claim on a public entity.
- Fault: Arizona follows pure comparative negligence — being partly, or even mostly, at fault reduces your recovery but does not bar it.
- Damage caps: Arizona is unusual: its constitution prohibits caps on injury or death damages, so a statutory cap does not limit what you can recover.
- Multiple defendants: Arizona generally applies several (not joint) liability, so each responsible party is accountable for its own share.
