STATE LAW – ARIZONA LIBRARY – GUIDE 19
Crash Damages
How Arizona evaluates medical expenses, future care, lost earnings, diminished earning capacity, pain and disability, loss of enjoyment of life, property damage, and other proven crash-related loss.
Arizona compensatory damages are built from proven economic and noneconomic loss caused by the crash.
Recoverable loss may include reasonable medical expense, future medical care, lost earnings,
diminished earning capacity, property damage, pain, discomfort, disability, disfigurement,
anxiety, and loss of enjoyment of life when supported by the evidence and legally caused by the defendant’s fault.
ARIZONA CONSTITUTION
Article II, § 31 prohibits laws limiting the amount of damages recoverable for death or personal injury,
subject to its stated crime-victim exception. Article XVIII, § 6 separately protects the right of action
for injuries from abrogation and statutory damages limitations, subject to the same stated exception.
01
ECONOMIC DAMAGES
Document financial loss category by category
A
Past medical expense
Hospital, physician, therapy, imaging, pharmacy, equipment, rehabilitation, and other crash-related care supported by admissible evidence.
B
Future medical care
Reasonably probable future treatment, medication, rehabilitation, equipment, attendant care, and other medical needs supported by the evidence.
C
Lost earnings
Income and employment benefits actually lost because of the crash-related injury.
D
Diminished earning capacity
Reduction in the injured person’s future ability to earn, which is analytically different from wages already lost.
E
Property loss
Vehicle repair or value loss, damaged personal property, towing, storage, and other properly supported property-related loss.
F
Other proven economic loss
Additional measurable financial consequences may be recoverable when they are legally caused, properly proved, and not duplicative.
PROOF, NOT LABELS
Calling an item a “damage” does not make it recoverable. Keep the source document, causal link,
amount, time period, and witness or expert foundation for each claimed category.
02
MEDICAL EXPENSES
Medical bills require a damages foundation; payment status is a separate issue
Arizona personal-injury damages practice treats reasonable medical expenses caused by the injury as a compensable category,
but a billed charge should not be treated as automatically reasonable, necessary, causally related, or admissible merely because it appears on an invoice.
Past care
- Provider and date of service
- Condition treated
- Charge and payment history
- Causal relationship to the crash
- Foundation for reasonableness and necessity where disputed
Future care
- Type of anticipated treatment
- Probability or evidentiary basis
- Expected timing and frequency
- Projected cost
- Whether life expectancy or future duration matters
LOPEZ
Lopez v. Safeway Stores, Inc. applied Arizona’s collateral-source rule and permitted the plaintiff
in that case to present reasonable billed medical expenses without reducing the claim by contractual write-offs.
The decision does not make every billed amount automatically reasonable, necessary, caused, or recoverable.
03
FUTURE LOSS
Future damages require evidence, not speculation
Future medical expense
The claim should identify the future care that is reasonably probable, why it will be needed,
when it is expected, and the evidentiary basis for its projected cost.
Diminished earning capacity
The question is the injury’s effect on the person’s future earning power—not merely wages missed to date.
Employment history, training, restrictions, career path, medical limitations, vocational evidence, and economic evidence may all matter.
SAIDE
Arizona authority recognizes that future medical expense is evaluated from the relevant circumstances and
should not be reduced to a requirement for a particular “magic word” from a medical witness. The evidentiary record as a whole remains critical.
04
NONECONOMIC DAMAGES
The injury’s human consequences are separate from the bills
Pain & discomfort
Physical pain, discomfort, and suffering already experienced and reasonably probable in the future.
Disability & disfigurement
Functional limitations, permanent impairment, scarring, disfigurement, and their demonstrated consequences.
Anxiety & emotional effects
Compensable emotional consequences supported by the evidence and caused by the injury.
Loss of enjoyment of life
Arizona jury-instruction materials recognize loss of participation in life’s activities as a damages component,
while cautioning against duplicative recovery.
Relationship loss
In qualifying cases, loss of consortium or loss of love, care, affection, companionship, and other relational interests
may be recoverable under Arizona law.
Duration matters
The same diagnosis may produce very different damages depending on recovery time, permanency, activity limits,
age, work, family roles, and the person’s pre-injury life.
DOCUMENT FUNCTION, NOT JUST SYMPTOMS
Contemporary journals, photographs, work records, family testimony, activity evidence, therapy records,
restrictions, and objective functional changes can make the noneconomic claim concrete without reducing it to a formula.
05
VEHICLE & PROPERTY DAMAGE
Repair cost and market-value loss are related but not identical
Repairable vehicle
Preserve estimates, final invoices, photographs, frame or structural measurements, parts information,
repair documentation, and evidence of value before and after the loss.
Residual diminished value
Oliver v. Henry holds that a vehicle owner need not first sell or trade the repaired vehicle to prove
residual diminution in market value. Competent evidence may establish the remaining loss.
PROOF OF VALUE
Use market evidence appropriate to the particular vehicle and condition. An asking price, automated valuation,
repair estimate, or owner’s opinion may have different evidentiary weight depending on the foundation and purpose.
06
COLLATERAL SOURCES
Who paid an expense and what damages were caused are separate questions
Arizona follows the collateral-source rule in ordinary tort cases: compensation from an independent collateral source
generally does not reduce the wrongdoer’s liability merely because another source paid some or all of the loss.
Examples of collateral-source issues
- Health insurance payments
- Contractual provider write-offs
- Workers’ compensation
- Medicare / Medicaid / AHCCCS
- Disability benefits
- Employer-provided benefits
Reimbursement is separate
A collateral source may have lien, reimbursement, subrogation, or statutory recovery rights against the settlement
or judgment. Those issues do not answer the initial damages question and belong in the MedPay, Medical Liens & Reimbursement topic.
DO NOT DOUBLE COUNT
The collateral-source rule does not authorize duplicate recovery of the same element under multiple labels.
Build a single damages ledger and separately track liens, reimbursement claims, write-offs, and amounts actually paid.
07
DEADLINES & SPECIAL LIMITS
No general damages cap does not mean there are no procedural limits
General crash limitations period
A.R.S. § 12-542 generally provides a two-year limitations period for personal-injury and property-damage actions,
subject to accrual rules and other statutory exceptions.
Public-entity claims are different
Arizona governmental claims can require a notice of claim within 180 days and suit within one year.
Use the Government Vehicle Crashes topic rather than relying on the general two-year period.
CONSTITUTIONAL RULE IS NOT “UNLIMITED DAMAGES”
Arizona’s anti-cap provisions prevent statutory limits of the type prohibited by the Constitution.
A claimant must still prove legally recoverable damages, causation, and amount, and other substantive doctrines may limit recovery.
08
PRACTICAL METHOD
Maintain one damages ledger from intake through resolution
1
List every claimed category
Medical, future care, earnings, earning capacity, property, noneconomic, relational, and other asserted loss.
2
Link each item to evidence
Bill, record, receipt, tax return, wage statement, expert report, photograph, repair record, witness, or other source.
3
Link each item to causation
Identify how the crash legally caused or contributed to the claimed loss.
4
Separate past from future
Keep incurred loss distinct from projected future care, impairment, earnings, and other prospective damages.
5
Track gross bill / paid / write-off / lien separately
Do not allow billing data, collateral-source payments, and reimbursement obligations to collapse into one number.
6
Document function over time
Record restrictions, milestones, setbacks, permanent limitations, activity changes, work effects, and family-role effects.
7
Avoid duplication
Review whether different labels describe the same actual loss before including them as separate components.
09
PRIMARY & OFFICIAL SOURCES
Authorities for this guide
SOURCE-CONTROL NOTE
The registry confirms Lopez as a published Arizona Court of Appeals decision and notes Arizona Supreme Court review was denied.
Because the durable direct official archived opinion-file URL remains unresolved, this guide links Lopez to the
Arizona Judicial Branch opinion-search system rather than treating a commercial case copy as the authoritative source.

VERIFICATION
Formal QC for an Arizona damages conclusion
- Identify each damages category separately and avoid duplication.
- Link every economic item to documentary or testimonial proof.
- Establish a causal relationship between the crash and the claimed loss.
- For medical expenses, distinguish billed amount, paid amount, contractual write-off, lien, and reimbursement interest.
- Do not treat Lopez as proof that every billed medical charge is automatically reasonable or necessary.
- For future medical care, identify the evidentiary basis for probability, duration, and cost.
- For diminished earning capacity, distinguish future earning power from wages already lost.
- For diminished vehicle value, preserve competent market evidence and repair documentation.
- Apply comparative fault before presenting a net-recovery illustration.
- Check liens and reimbursement rights separately before settlement.
- Calendar the governing limitations period and any shorter special statute.
- Treat State Bar jury instructions as secondary guidance, not controlling law.
QC STATUS
Arizona Constitution art. II, § 31 and art. XVIII, § 6 and A.R.S. § 12-542 were checked against current official
Arizona Legislature sources on September 26, 2026. Lopez, Oliver, and collateral-source authority were cross-checked
against the registry and Arizona Judicial Branch materials; Lopez remains flagged for durable direct official-source URL closure.

COMMON QUESTIONS
Questions to ask
Does Arizona cap ordinary personal-injury damages?
Arizona Constitution art. II, § 31 and art. XVIII, § 6 prohibit statutory damages limitations of the kind covered by those provisions, subject to the Constitution’s stated crime-victim exception. A claimant still must prove legally recoverable damages and causation.
Can an injured person recover medical expenses that health insurance paid?
Arizona’s collateral-source rule can prevent an independent collateral payment from reducing the tortfeasor’s liability merely because another source paid the expense. The medical-expense claim still requires the appropriate damages foundation, and reimbursement or lien rights must be addressed separately.
Can the plaintiff claim the full medical bill even if the provider accepted less?
Lopez permitted evidence of reasonable billed medical expenses without reducing the claim by contractual write-offs in the case before the court. It does not mean every billed amount is automatically reasonable, necessary, caused, or recoverable.
Are future medical expenses recoverable?
They may be when the evidence establishes reasonably probable future care and an adequate basis for the amount. The issue should be supported by the complete medical and damages record rather than speculation.
Is lost earning capacity the same as lost wages?
No. Lost wages concern earnings already missed; diminished earning capacity concerns reduction in the person’s future ability to earn.
Can a repaired vehicle still have a diminished-value claim?
Yes, when supported by competent evidence. Oliver v. Henry holds that an actual sale or trade is not required before residual diminution in market value can be proved.
Does a claimant need receipts for pain and suffering?
No receipt measures noneconomic harm. But the nature, duration, severity, functional effect, medical evidence, witness evidence, and other facts should support the claimed human consequences of the injury.
Is the statute of limitations always two years?
No. Section 12-542 supplies the general Arizona personal-injury/property-damage period, but public-entity claims and other specialized claims can have different or shorter deadlines.
