How to Establish Fault in Arizona Accident Cases

Determining fault, proving fault, and how fault impacts an award of damages.

Whether or not you recover damages after a personal injury accident will depend on who is at fault. The legal term synonymous with fault is “negligence.” While it’s obvious who was at fault in certain accidents, liability in other cases is harder to establish.

This article explores the role of fault in Arizona accident cases, including how fault is established and how fault might impact the amount of damages you receive.

Fault in automotive accidents

In some states, lawmakers have tried to cut down on the number of lawsuits (and the cost of insurance) by instituting a no-fault insurance system. In these states, each driver pursues compensation through their own insurance provider regardless of who’s at fault for the accident. The process reduces the costs associated with insurance claims and litigation because any dispute about who caused the accident is irrelevant. Because of this, insurance companies in no-fault states tend to pay claims more quickly.

On the other side of the coin are states with a fault-based insurance system. In these states, the at-fault driver (or their insurer) is responsible for paying the other parties damages. This means that the other driver and their insurer can (and often do) dispute liability.

Arizona has a fault-based insurance system. This means that if you’re an insured driver and you get into a car accident in Arizona, you have three options:

1. File a claim with your car insurance provider
2. File a claim with the at-fault driver’s insurance provider
3. File a civil lawsuit against the other driver

What if the at-fault driver has no insurance?

If the at-fault driver has no liability insurance, you can make a claim with your own insurance provider so long as you purchased uninsured motorist coverage.

Similarly, if the at-fault driver is underinsured (i.e., the amount of your damages exceeds the limits of the at-fault driver’s coverage), you can make a subsequent claim against your own insurance company so long as you purchased underinsured motorist coverage.

In Arizona, both uninsured and underinsured motorist coverage are optional.

Personal injury protection (PIP insurance)

Personal injury protection (PIP) insurance is a no-fault insurance policy that provides injured drivers with up to $10,000 in immediate medical coverage regardless of who was at fault for the accident. PIP insurance generally covers:

• Hospital and doctor’s bills
• Prescriptions
• Lost wages
• Funeral expenses

While PIP insurance is mandatory in many states like Florida, it’s optional in Arizona. As a result, you can only make a PIP claim if you bought PIP insurance prior to your injury.

Who can be at fault?

Most car accidents are caused by driver error or negligence. But sometimes, a road hazard causes the accident (or at least contributes to the accident). Some common road hazards that cause car accidents in Arizona include:

• Potholes
• Road debris
• Obstructed signs
• Poor lighting
• Absence of warning signs

If you’re injured in an accident that was partly or completely caused by a road hazard, someone other than another driver may be liable. Depending on the hazard, the liable party might be the public works department, the city, or some other public entity.

Comparative fault

In some cases, the person who you believe is at fault turns around and tries to blame you for the accident. The question then becomes: Were both of you at fault? And if so, to what degree?

Arizona follows the pure comparative fault theory. Under this theory, the amount of damages a plaintiff can recover is reduced by a percentage that reflects their own degree of fault – no matter what that percentage may be.

Let’s say the other driver failed to stop at a red light and crashed into you. But according to the police report you were driving at night without your headlights. A jury might find that you were 30% at fault and the other driver was 70% at fault. Under Arizona’s comparative fault law, you would only be able to recover 70% of your damages from the other driver.

Establishing fault

As discussed above, fault is generally based on another person’s carelessness. The legal term for this carelessness is negligence.

In Arizona, you must prove three elements to establish negligence:

• The other person owed a duty of reasonable care (all drivers have a duty to drive carefully and obey all traffic laws)
• The other person breached that duty (the other person didn’t drive carefully or didn’t obey a traffic law)
• You were injured and incurred damages as a result of the other person’s breach

Proving fault

Sometimes liability in an accident is clear and the only issue to be resolved is the amount of damages. Other times, liability is unclear. In these cases, an experienced attorney can help you develop the evidence necessary to establish fault. This evidence may include:

• Police reports
• Accident reconstruction analysis
• Videos or photographic evidence
• Witness statements
• Electronic crash data
• Medical records and billing statements
• Traffic citations
