Who Is Liable for a Self-Driving Car Crash in Arizona?
In an ordinary crash, the question is which driver was at fault. With a self-driving car, that question changes — there may be no at-fault human driver at all, and responsibility can shift to the companies behind the vehicle.
The possible responsible parties
Depending on the vehicle and the crash, responsibility may rest with the company operating the vehicle (like a robotaxi service), the manufacturer, the maker of the self-driving software or sensors, or another driver who was actually at fault. Often more than one is involved.
Product liability and negligence
When the vehicle's own systems caused the crash, product-liability principles can apply to the maker, and negligence theories can apply to the company operating the vehicle. Because the field is new, these cases are built carefully with the data and experts.

Frequently asked questions
Is anyone liable if a self-driving car with no driver crashes?
Yes — responsibility can shift to the company operating the vehicle, the manufacturer, or the maker of the self-driving system. The absence of a human driver does not mean no one is responsible.
How do you figure out who caused an AV crash?
By preserving and analyzing the vehicle's extensive data and sensor logs with experts, along with the usual crash evidence. That analysis is central to identifying the responsible company.
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.
