Preserving Evidence After a Arizona Truck Accident
In a truck case, the evidence that proves what happened often belongs to the other side — and it does not last. Acting quickly to preserve it is one of the most important things that can be done for your claim.
The evidence that matters most is perishable
Electronic engine and logging data can be overwritten, the truck can be repaired or returned to service, dashcam footage can be recorded over, and paper records can be routinely destroyed on a schedule. Much of this is controlled by the trucking company, which has little incentive to keep proof that could establish its own liability.
The preservation demand
A prompt written demand — a legal hold, sometimes called a spoliation letter — puts the trucking company and its insurers on formal notice to preserve the truck, its data, the driver's records, and related documents. Sent early, it can stop routine destruction and lock down the proof before it is gone.
What we move to preserve
That typically includes the truck's engine and event-recorder data, the driver's electronic logs and qualification file, inspection and maintenance records, dispatch and delivery records, dashcam or nearby camera footage, and the physical truck itself for inspection. The list is tailored to the crash.

Frequently asked questions
What is a spoliation letter?
It is a formal notice demanding that the other side preserve specific evidence for a claim. If they destroy it anyway after receiving notice, a court may impose consequences, which gives the demand real teeth.
How soon does the letter need to go out?
As soon as possible. Because truck data and records can be overwritten or destroyed within weeks, waiting even a short time can mean losing evidence that cannot be recreated.
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.
