Who Is Liable in a Truck Accident?

San Jose, United States – May 4, 2026 / Hann Law Firm /

Sharing the road with a large commercial truck can seem ordinary until a collision changes everything. After a crash, many victims in San Jose, CA, are left wondering who is actually responsible for their losses. The answer may involve more than one party.

Hann Law Firm helps injured victims understand how truck accident liability is determined and which parties may share responsibility for a crash.

Who Is Liable in a Truck Accident?

Fault in a truck accident rarely falls on a single person or company. Multiple parties can share responsibility, depending on the circumstances.

Common parties who may be held liable include:

The truck driver: Driver fatigue and negligence, including distracted driving, speeding, or driving under the influence, are among the leading causes of commercial truck crashes.
The trucker’s company: Carriers may be liable for inadequate training, unsafe internal policies, or poor hiring practices. The vicarious liability of trucking companies also applies when a driver causes harm while working within the scope of employment.
Parts manufacturers: When a defective tire, brake system, or steering component contributes to a collision, product liability law could hold the manufacturer accountable.
Cargo loaders: Cargo loading liability may arise when an improperly loaded or overloaded shipment causes a truck to tip or jackknife en route to its destination.

Identifying which party or parties played a role in the crash is crucial when building a legal claim in San Jose.

How California Law Affects Truck Accident Cases in San Jose

California follows a rule called pure comparative negligence in truck accidents, which means that multiple parties may be at fault based on their percentage of responsibility. Even if an injured person is found partially at fault, they may still recover a portion of their damages.

Hann Law Firm serves clients across San Jose and understands how state and federal regulations factor into these determinations. Courts and insurance adjusters may look closely at possible safety violations leading up to the crash.

Federal Regulations and Truck Accident Liability

Both federal and California state regulations set the standard for safe trucking operations, and violations of those rules can contribute to a finding of fault. Investigators, insurers, and courts typically examine several key areas during fault disputes.

Hours of service violations often fall under scrutiny. Federal rules generally limit interstate drivers to 11 hours of driving within a 14-hour window, following a minimum 10-hour rest period.

Maintenance and inspection failures may also be under review, as commercial trucks must undergo routine checks and remain in roadworthy condition. Driver qualification records and drug and alcohol testing compliance also fall under review when parties dispute truck accident liability in San Jose.
