Semi-truck accidents cause serious injuries and fatalities onp Arizona roads every year. When a collision involves a commercial vehicle, determining who bears legal responsibility can be complex. Multiple parties may be held liable, including the truck driver, the trucking company, cargo loaders, maintenance providers, other motorists, and manufacturers. Understanding how Arizona law allocates fault is important if you’ve been injured in a semi-truck accident and are considering a claim.

Understanding Trucking Company Negligence in Arizona
Trucking company negligence occurs when a commercial carrier fails to meet its legal duties to the public, such as through unsafe hiring, training, supervision, scheduling, or maintenance practices. Companies can face liability even if their representatives were not physically present at the crash. Arizona recognizes vicarious liability doctrines, including principles similar to respondeat superior or agency liability, under which an employer can be responsible for harm caused by employees acting within the course and scope of their employment.
Arizona applies a pure comparative negligence standard under ARS § 12-2505. You may recover compensation even if you share some fault; your award is reduced by your percentage of responsibility. For example, if your damages total $100,000 and you are found 20% at fault, your potential recovery could be reduced to $80,000. Trucking companies have duties to reasonably screen and train drivers, maintain equipment, and follow safety regulations; when those duties are breached and contribute to a crash, the company can bear a share of responsibility.
Common Types of Trucking Company Negligence
Negligent Hiring and Retention
Carriers are expected to review driving histories, prior employment, and other relevant background information before putting drivers on the road. Hiring or keeping drivers with serious traffic violations, safety violations, or a history of preventable crashes can support negligent hiring or retention claims if those drivers later cause a collision.
Inadequate Training and Supervision
Drivers of large commercial vehicles must be trained on safe operation, defensive driving, and applicable federal and state rules. Companies that fail to provide appropriate training or do not monitor driver performance can be found negligent if poor training or lax supervision contributes to a crash. Examples include not addressing repeated speeding, distracted driving, or hours-of-service violations.
Unsafe Scheduling and Hours-of-Service Problems
Federal regulations limit how long most truck drivers can drive and work without rest to reduce fatigue. The Federal Motor Carrier Safety Administration (FMCSA) establishes hours of service regulations that require drivers to take adequate rest periods. When company policies or delivery schedules make it difficult to comply with these limits, or when management tolerates or encourages violations, crash risk increases. Evidence of unrealistic schedules or ignored hours-of-service violations can support claims that the company contributed to the collision.
Vehicle Maintenance Negligence
Trucking companies must maintain their fleets in a safe operating condition, including brakes, tires, steering, and lighting. Skipped inspections, deferred repairs, or ignoring driver-reported problems can lead to mechanical failures that cause or worsen crashes. Maintenance and inspection records are often examined to see whether required steps were taken. Under NHTSA safety standards, vehicles must meet specific crashworthiness and equipment requirements.
Who Else Can Be Held Liable in a Semi-Truck Accident
Liability in an Arizona semi-truck crash can be shared among several parties:
- Truck driver: May be liable for negligent driving, such as speeding, distraction, following too closely, or driving while fatigued or impaired.
- Trucking company/motor carrier: Can be vicariously liable for an employed driver’s negligence and directly liable for unsafe policies, hiring, training, or maintenance practices.
- Cargo loading company: May share responsibility if improper loading or securement causes the truck to become unstable, jackknife, or spill cargo. Improperly loaded cargo is a common cause of serious truck accidents.
- Truck or parts manufacturer: May be liable if a design or manufacturing defect in brakes, tires, steering, or other components contributed to the crash.
- Maintenance provider: If a third-party shop performed deficient repairs or inspections, it may bear part of the blame.
- Other motorists or road users: Drivers of passenger vehicles, other trucks, or motorcycles can share fault if their negligence contributed to the collision.
- Government entities: In some cases, a public entity responsible for road design, maintenance, or traffic control may bear partial liability for unsafe conditions.
Identifying all potentially liable parties is important because it can increase the total insurance coverage available to an injured person.
How Arizona Law Determines Liability
Arizona uses a pure comparative negligence rule, which allows fault to be divided among all involved parties, including the injured person. Each party is assigned a percentage of responsibility based on their contribution to the crash. Your compensation is then reduced by your own share of fault. Unlike some states, Arizona does not bar recovery even if you are more at fault than others, though your recovery decreases as your percentage increases.
Fault allocation is based on evidence such as:
- Police and crash reports.
- Physical evidence from the scene.
- Electronic data (black-box, ECM, dash-cam, and telematics).
- Witness statements.
- Company records and regulatory compliance documents.
Most Arizona personal injury claims, including many truck accident cases, are subject to a two-year statute of limitations under ARS § 12-542, measured from the date of injury, with some exceptions. Acting promptly helps preserve evidence like electronic logs and maintenance records, which can otherwise be overwritten or lost.
Steps to Take After a Semi-Truck Accident
If you are involved in a semi-truck crash, the following steps can help protect your health and potential claim:
- Seek emergency or urgent medical care, even if you feel only minor pain.
- Call law enforcement so the collision is officially documented.
- If it is safe, take photographs or video of vehicle positions, damage, skid marks, cargo spillage, and road conditions.
- Gather contact and insurance information for the truck driver and any other drivers, and obtain names and contact details for witnesses.
- Avoid discussing fault at the scene or on social media.
- Notify your own insurer about the crash according to your policy.
- Contact an attorney as soon as possible so preservation letters can be sent for electronic logging data, driver qualification files, and maintenance records.
Frequently Asked Questions
Can I sue a trucking company if the driver was at fault?
In many cases, yes. Under Arizona law and general agency principles, you can often bring claims against both the driver and the trucking company. The company may be vicariously liable for an employed driver’s negligence and directly liable for its own unsafe hiring, training, or maintenance practices.
What damages can I recover in a truck accident case?
Depending on the facts, recoverable damages can include medical expenses, lost wages, diminished earning capacity, property damage, and non-economic losses such as pain and suffering, emotional distress, and loss of enjoyment of life. In fatal cases, surviving family members may pursue wrongful death damages under Arizona law.
How long do I have to file a claim in Arizona?
In most Arizona truck accident injury cases, you generally have two years from the date of the crash to file a lawsuit under ARS § 12-542, subject to specific exceptions and special rules (for example, claims against government entities often have shorter notice requirements). Because important evidence can be lost over time, it is wise to speak with an attorney well before any deadline.
What evidence is needed to prove trucking company negligence?
Evidence can include driver qualification and training records, electronic logging device data, GPS and telematics records, maintenance and inspection reports, prior violation and crash histories, and company safety policies. Accident scene evidence, medical records, and witness testimony remain central to showing how the crash occurred and what harm it caused.
What is the difference between driver negligence and company negligence?
Driver negligence focuses on the individual driver’s behavior at the time of the crash, such as speeding, distraction, or following too closely. Company negligence focuses on the carrier’s broader conduct—who it hires, how it trains and supervises drivers, how it maintains trucks, and how it structures routes and schedules. Both types of negligence can exist in the same case.
Will my case go to trial or settle?
Many truck accident cases settle through negotiations or mediation once liability and damages are better understood. Some, however, proceed to trial when liability is strongly disputed, or settlement offers do not fairly reflect the injuries and losses. A firm that is prepared to try cases can often negotiate from a stronger position because insurers know a trial is a viable option.
