Truck accident liability in Arizona rarely points to a single party. The driver, the trucking company, the maintenance contractor, the cargo loader, and even truck part manufacturers may share responsibility. How fault is split affects what you can recover and from whom.
Arizona Follows Pure Comparative Negligence
Under ARS §12-2505, Arizona courts can apportion fault among all parties — including you — and your recovery is reduced by your share. Even if you were 30% at fault, you can still recover 70% of your damages. This differs from "modified" comparative-fault states, where over 50% fault means zero recovery.
Driver Negligence
The most direct liability path: the truck driver was distracted, fatigued, drunk, speeding, or made an unsafe maneuver. Driver liability is established through ELD records (showing hours-of-service violations), eyewitness testimony, and accident reconstruction.
Trucking Company Negligence
The trucking company can be liable for negligent hiring (drivers with prior DUIs, unsafe driving records), failure to train, dispatching drivers who exceeded safe limits, or pressuring drivers to violate hours of service. Company records are critical evidence.
Maintenance and Inspection Failures
Federal rules require regular truck inspections and maintenance. If brakes failed because the trucking company skipped inspections, the company is liable. If a tire blew because of a manufacturer defect, the tire maker may be liable.
Cargo Loader Liability
When cargo shifts in transit and causes a crash — common with overloaded or improperly secured loads — the loader (often a different company than the trucker) can be sued. Cargo manifests, weight tickets, and loading records are key evidence.
Government Liability
Dangerous road conditions, missing signage, or defective traffic signals can make a government entity liable. Arizona's Tort Claims Act (ARS §12-821.01) requires a notice of claim within 180 days, separate from the standard two-year statute of limitations.
How We Build the Liability Case
We start with crash reconstruction, secure electronic data, request driver and dispatch records, and trace the chain of custody for cargo. The goal is to identify every responsible party and every available insurance policy. Multiple defendants typically means more total coverage available.

What if the truck driver was an employee vs an independent contractor?
Either way, the trucking company can be liable for the driver's negligence under different legal theories — respondeat superior for employees, statutory liability for motor carriers using independent contractors. The label rarely defeats the case.
Can I recover if I was partially at fault for the truck accident in Arizona?
Yes. Under ARS §12-2505, you can recover even if you were over 50% at fault — your recovery is just reduced by your percentage of fault.
How long does fault determination take in an Arizona truck case?
Initial liability assessment: weeks. Final determination through reconstruction, expert review, and discovery: months. Don't wait for fault to be settled before getting legal help — preservation steps need to happen immediately.
