Who Is Liable When a Semi-Truck Causes an Accident — the Driver or the Company?

When a semi-truck accident occurs, determining liability is crucial for victims seeking compensation. In Arizona, both the truck driver and the trucking company can be held responsible, depending on the circumstances of the accident.

Recent Case in Phoenix

In February 2026, a tragic accident on Interstate 10 near Buckeye, Arizona, highlighted the complexities of semi-truck accident liability. A car crossed all lanes of eastbound I-10 and collided with an Amazon semi-truck, causing it to roll over. The driver of the car was killed at the scene. This incident underscores the importance of thorough investigations to determine fault and liability in such accidents. [Source: AZFamily]

Arizona Law and Your Rights

Under Arizona law, several parties may be held liable in a semi-truck accident:

The Truck Driver: If the driver was negligent—such as driving under the influence, speeding, or violating traffic laws—they can be held personally responsible.

The Trucking Company: Companies are often liable under the doctrine of “respondeat superior,” meaning they are responsible for the actions of their employees performed within the scope of employment. Additionally, if the company failed to maintain the vehicle properly, enforce safety regulations, or hired unqualified drivers, they could be held directly liable.

Maintenance Providers: If a third-party maintenance provider’s negligence led to mechanical failures causing the accident, they might also be held accountable.

Arizona follows a “pure comparative negligence” rule, meaning that even if you are partially at fault, you can still recover damages, though your compensation will be reduced by your percentage of fault. [Source: Burg Simpson]

Statute of Limitations

In Arizona, the statute of limitations for personal injury claims, including those arising from semi-truck accidents, is two years from the date of the accident. Failing to file within this period can result in losing your right to seek compensation. [Source: FindLaw]
