ARIZONA GUIDE 19

Crash Damages

Damages measure the legally compensable loss caused by the crash—not the size of the insurance policy. Arizona crash damages can include medical care, future treatment, lost earnings, diminished earning capacity, disability, pain, loss of enjoyment of life, qualifying consortium, vehicle damage and other proven losses.

Damage Map

Preexisting Conditions

Start with the complete loss—not the insurance offer

Medical expenses, lost income, future earning loss, property damage and other financial consequences capable of economic proof.

Pain, disability, disfigurement, loss of enjoyment of life and other human consequences of physical injury.

Punitive damages require a separate, substantially heightened Arizona showing and are not part of an ordinary negligence valuation.

Every damage item needs a causal bridge

A loss occurring after a crash is not automatically a loss caused by the crash.

Existence

Did the claimed expense, limitation or loss actually occur?

Causation

Did the defendant’s conduct cause or aggravate that loss?

Amount

Is there a reasonable evidentiary basis for the value claimed?

Medical damages require more than adding invoices

Arizona permits recovery of reasonable expenses for necessary medical care caused by the tort.

Reasonable

The amount claimed must have a sufficient basis as a reasonable charge or reasonable value for the treatment.

Necessary

The treatment must relate sufficiently to the medical consequences being claimed.

Causally related

The crash must have caused or aggravated the condition requiring treatment.

Health-insurance write-offs do not automatically reduce Arizona tort damages

Lopez v. Safeway Stores applied Arizona’s collateral-source rule to contractual reductions in medical bills.

Reasonable medical expense

The claimant may seek the full amount of reasonable medical expenses charged for crash-related treatment.

Amount insurer happened to pay

A collateral insurer’s negotiated payment or contractual write-off does not automatically become the tortfeasor’s damages ceiling.

Future medical care must be reasonably probable

Arizona does not permit a jury to guess about possible future treatment.

Probability

The evidence as a whole must support that the treatment is reasonably probable—not merely imaginable.

Cost

There must be evidence from which the likely expense can be reasonably estimated.

Possible future-care evidence

treating physician opinion
surgical recommendation
life-care plan
therapy frequency
medication need
durable medical equipment
home assistance
future imaging
anticipated replacement devices
documented cost estimates

Past lost earnings and future earning capacity are different losses

Lost earnings

Specific income the claimant would have earned during an identifiable period but for the injury.

Diminished earning capacity

Reduction in the person’s ability to earn income in the future because of lasting injury.

Past earnings proof

pay stubs
W-2s
1099s
tax returns
commission records
employer verification
work schedule
medical work restrictions

Earning-capacity proof

permanent restrictions
education
training
occupation
work history
vocational assessment
labor-market evidence
economic analysis
reduced work life
lost occupational options

The human loss is not measured by a medical-bill multiplier

Noneconomic damages address consequences for which no invoice exists.

Pain & suffering

Physical pain, discomfort, suffering and anxiety associated with the injury.

Disability

Loss of physical or cognitive function and independence.

Loss of enjoyment

Reduced ability to participate in ordinary, recreational, family and personal activities.

Disfigurement

Scars, burns, amputations and other permanent changes in physical appearance.

Treatment burden

Surgery, therapy, medication, repeated appointments and recovery periods.

Loss of independence

Need for assistance with transportation, mobility, self-care or household tasks.

A vulnerable claimant is still entitled to compensation for harm the crash actually caused

A preexisting condition does not give a negligent defendant the right to injure only a perfectly healthy person.

Pre-crash condition

The defendant is not automatically responsible for disability, symptoms or treatment that would have existed regardless of the crash.

Crash-related aggravation

New injury or worsening causally attributable to the crash can be compensable.

medical causation opinion

Severe injury can damage family relationships as well as the injured person

Arizona recognizes qualifying derivative loss-of-consortium claims.

Relationship

Consortium concerns loss of love, affection, society, companionship, comfort, care and related relational interests.

Underlying claim

The claim is derivative and depends on an actionable injury to the primary claimant.

Functional loss can also create economic replacement costs

A claimant who cannot perform ordinary services because of injury may require substitute assistance.

Household

Cleaning, cooking, laundry and routine household services.

Family care

Child care and other responsibilities formerly performed by the injured person.

Physical tasks

Yard work, home maintenance, transportation and personal assistance.

Vehicle damage is more than a body-shop estimate

For a repairable vehicle, Arizona recognizes separate property-damage components.

Repair cost

Reasonable cost of returning the vehicle to an appropriate repaired condition.

Diminished value

Residual loss in fair market value even after proper repair.

Loss of use

Compensable deprivation of the vehicle during a reasonable repair period.

Diminished value does not require an actual sale

Oliver v. Henry holds that a repaired Arizona vehicle owner does not have to sell the vehicle merely to prove that the crash reduced its market value.

A total-loss dispute is fundamentally a valuation dispute

Preserve evidence of the vehicle’s condition immediately before the crash.

A $100,000 policy does not make a $500,000 injury worth $100,000

Question	Example
Total proven damages	$500,000
At-fault liability limit	$100,000
Remaining uncompensated damages	$400,000 before other coverage, fault and collection issues.
Next investigation	Umbrella, employer, additional policies, UIM, stacking and other coverage sources.

Value total damages before reducing them for claimant fault

Guide 17 explains Arizona’s pure comparative-fault system.

Step	Illustration
Total compensable damages	$500,000
Claimant comparative fault	20%
Remaining comparative recovery	$400,000
Then	Apply defendant/nonparty allocation, settlements, insurance and collectibility.

The injured person must also act reasonably after the loss

The duty to mitigate concerns additional damages that reasonably could have been avoided.

Medical mitigation

Whether reasonable treatment or rehabilitation could have avoided additional loss.

Employment mitigation

Whether suitable work within legitimate medical restrictions was reasonably available.

Property mitigation

Whether towing, storage, repair or replacement costs were unnecessarily prolonged.

Proof remains important

Mitigation is not a license to speculate about what the claimant theoretically could have done.

Punitive damages require much more than a serious crash

Swift Transportation v. Carman is especially useful because it applies Arizona’s punitive-damages doctrine in a motor-vehicle negligence case.

The heightened showing

Intent to harm

Defendant intended to cause the injury.

Spite / ill will

Defendant acted from the kind of culpable motive Arizona treats as punitive.

Outrageous conscious disregard

Defendant consciously pursued conduct known to create a substantial risk of significant injury.

Damages development does not suspend Arizona deadlines

A.R.S. §12-542 generally provides a two-year limitations period for personal-injury and property-damage actions.

Common Arizona damages mistakes

“The claim is worth the policy limits.”

Wrong analytical order. First determine damages; then determine what insurance can satisfy them.

“Add all medical bills and multiply by three.”

Arizona damages do not use a legally prescribed medical-bill multiplier.

“Every billed medical charge is automatically recoverable.”

No. Reasonableness, causation and treatment relevance remain necessary.

“Health insurance paid it, so the tortfeasor owes nothing.”

Arizona’s collateral-source rule generally rejects that automatic reduction.

“The doctor said future surgery is possible, so include it.”

Future care must have sufficient evidence of reasonable probability and cost under Saide.

“The claimant returned to work, so earning capacity is zero.”

Rossell distinguishes present wage loss from permanent diminution in the ability to earn.

“The claimant had arthritis before the crash, so none of this is recoverable.”

Arizona allows recovery for crash-caused aggravation and for greater harm caused because of unusual susceptibility.

“Repairing the car ends the property claim.”

Arizona recognizes residual diminished value and loss of use when properly proven.

“Speeding means punitive damages.”

Swift requires substantially more than ordinary or even gross negligence.

“We can wait until treatment ends before worrying about deadlines.”

Limitations periods operate independently of the medical recovery timeline.

Arizona authority map

Constitutionally prohibits legislation limiting the amount of damages recoverable for causing death or personal injury, subject to the Constitution’s current provisions.

Arizona Constitution →

Protects the right of action for injuries and independently restricts statutory limitation of the amount recovered, subject to the Constitution’s express exception.

Automobile-injury authority illustrating jury evaluation of medical expenses, wage loss, preexisting conditions and future earning capacity.

Applies Arizona’s collateral-source rule to contractual medical-bill write-offs and permits recovery of the full reasonable amount charged rather than limiting recovery to the amount paid by health insurance.

Read Lopez →

States Arizona’s collateral-source rule: qualifying payments or benefits from an independent source do not reduce the tortfeasor’s liability merely because they compensate the same harm.

Requires a sufficient evidentiary basis for reasonably probable future medical treatment and its cost and rejects purely speculative future-care awards.

Holds future surgery may be submitted to the jury when the evidence supports reasonable probability and supplies an evidentiary basis for cost.

Distinguishes specific lost earnings from diminished future earning capacity and confirms that permanent injury or disfigurement can support an earning-capacity claim where the evidence warrants it.

Recognizes Arizona’s unusually-susceptible-plaintiff principle: greater injury resulting from a claimant’s susceptibility remains compensable when caused by the defendant.

Recognizes qualifying parental loss-of-consortium claims where severe, permanent and disabling injury substantially interferes with the normal parent-child relationship.

Read Pierce →

Recognizes repair cost, residual diminution in value and loss of use as separate potentially compensable components of vehicle property damage.

Holds that an owner need not sell a repaired vehicle to prove diminished value; competent evidence such as appraisal can establish the pre-loss/post-repair difference.

Read Oliver →

Clarifies Arizona punitive damages in negligence cases: intent to harm, spite/ill will, or outrageous conscious disregard of a known substantial risk of significant harm; negligence and gross negligence are insufficient.

Read Swift →

Requires clear and convincing evidence of the punitive-damages mental state and reserves punitive damages for aggravated and outrageous misconduct.

Generally provides two years for personal-injury and property-injury actions, subject to accrual principles and claim-specific exceptions.

Read §12-542 →

Prohibits prejudgment interest on unliquidated damages and bars prejudgment interest on future, punitive and exemplary damages found by the trier of fact.

Frequently asked questions

Arizona’s Constitution broadly prohibits statutory limits on damages recoverable for personal injury or death. That does not eliminate the claimant’s burden to prove causation and compensable loss or special rules applicable to particular defendants or claims.

No. The medical care and claimed expense must be sufficiently connected to the crash, and the claimed medical expense requires an adequate basis for reasonableness and necessity.

Not automatically. Lopez applies Arizona’s collateral-source rule to contractual medical write-offs and permits recovery of the full amount of reasonable medical expenses charged rather than automatically limiting recovery to the insurer’s negotiated payment.

No. Lopez addressed collateral-source reductions; the reasonableness and causal relationship of the claimed medical expense remain separate issues.

Yes when the evidence supports that future treatment is reasonably probable and supplies a reasonable basis for its nature and cost.

Lost wages concern specific income already lost. Earning capacity concerns a lasting reduction in the person’s ability to earn income in the future.

Potentially. Returning to work does not necessarily prove that future earning ability is unchanged. Permanent restrictions, lost occupational choices or reduced future work capacity can still matter.

A defendant is not responsible for unrelated preexisting loss, but Arizona permits recovery for crash-caused aggravation and for greater injury caused because a claimant was unusually susceptible.

Arizona does not use a legally mandated medical-bill multiplier. The evidence should address the nature, duration and effect of the pain, disability, treatment and life disruption.

Potentially. Arizona recognizes residual diminution in fair market value as a separate component of a repairable vehicle’s property damage when adequately proven.

No. Oliver v. Henry holds that diminished value can be proven through other competent evidence such as appraisal.

No. That is an insurance-limit question. Total damages should be valued separately, then all liability, umbrella and UM/UIM sources should be investigated.

Mere negligence and even gross negligence are insufficient. Arizona’s Swift standard requires the substantially heightened culpable mental state described in that case, proven under the applicable punitive-damages standard.

Section 12-542 generally provides two years for personal-injury and property-damage actions, subject to accrual rules and exceptions. Government claims have substantially shorter deadlines.
