Arizona Current-Law Snapshot
Five features shape many Arizona crash claims
These are starting points for research rather than substitutes
for the current statute, policy language or controlling Arizona
appellate authority.
25 / 50 / 15
Arizona’s ordinary minimum motor-vehicle liability limits are
$25,000 per person, $50,000 per accident for bodily injury,
and $15,000 for property damage.
Pure Comparative Negligence
Arizona generally reduces damages according to the percentage
of fault allocated to the claimant rather than using a
50-percent recovery bar.
UM/UIM Must Be Offered
Arizona uses a statutory offer, selection and rejection
framework for uninsured and underinsured motorist coverage.
Several Liability
Arizona generally allocates responsibility among parties
according to their respective shares of fault, subject to
statutory exceptions.
Arizona MedPay Rules
Medical-payments coverage can involve an Arizona-specific
statutory reimbursement and lien framework that should be
considered when calculating net recovery.
DIFI
The Arizona Department of Insurance and Financial Institutions
is the state’s insurance regulator and an important source of
official regulatory and consumer information.
Arizona Research Library
Browse the 23-guide Arizona law library
Arizona uses the common VictimsGuide 23-topic taxonomy so the same
research issue can be followed across the Western States Law Library
without assuming that another state’s substantive law applies.

Resolution & Research
Arizona-Specific Features
Issues that deserve particular attention in Arizona
The common 23-guide structure supports interstate comparison,
but these Arizona doctrines require state-specific analysis.
UM/UIM Offer & Selection
Arizona requires careful review of the statutory UM/UIM offer,
selection and rejection process, together with the actual policy
and the insured’s coverage history.
Nonparty Fault
Arizona’s comparative-fault system can allocate responsibility
to properly identified nonparties, making early investigation
of every potentially responsible actor important.
MedPay Reimbursement
Arizona has a specific statutory structure governing qualifying
MedPay reimbursement interests, including issues that can affect
the claimant’s net settlement recovery.
Arizona Law Watch
UM/UIM stacking deserves current-status review
Arizona stacking law has continued to develop through recent
Supreme Court decisions. Policy structure, the number of vehicles,
the number of policies and the identity of the purchasers can
materially affect the analysis.
Current Case Watch
A.R.S. § 20-259.01(H) and Multiple Policies
Recent Arizona Supreme Court authority should be read together
with the statute and earlier stacking cases before deciding
whether several UM/UIM coverages may be combined. Obtain every
policy, identify the insured vehicles and purchasers, and examine
the anti-stacking language before reaching a conclusion.
Primary Authority
Official Arizona research sources
Current official authority controls over VictimsGuide summaries.
Use the library to identify the issue, then return to the governing
statute, regulation, policy language and appellate authority.
Research Standard
How to use the Arizona library
The purpose of the library is to organize primary authority and
practical questions into a repeatable research workflow.
Start with current Arizona law
Locate the current statute and any applicable administrative
rule before relying on an older summary, claim practice or
prior version of the law.
Read the actual policy
Declarations, definitions, exclusions, endorsements and
coverage-specific language remain central to insurance analysis.
Identify controlling cases
Use Arizona Supreme Court and precedential Court of Appeals
decisions to determine how statutes and policy provisions
operate in the particular legal context.
Using the Library
Frequently asked questions
Where should I begin?
Begin with Guide 01 for an overview of the Arizona system.
If you already have a claim, Guide 03 is a useful early step
because the value and structure of a case cannot be evaluated
reliably until the potentially applicable insurance has been identified.
Does Arizona use comparative negligence?
Yes. Arizona generally uses pure comparative negligence.
Claimant fault reduces recoverable damages proportionally rather
than automatically barring recovery at a 50-percent threshold.
Why is Arizona UM/UIM research especially important?
Arizona uses a detailed statutory UM/UIM framework, and
stacking questions can depend on the number of policies,
vehicles, purchasers, insureds and the language used in the
particular insurance contracts.
Are VictimsGuide summaries controlling law?
No. The operative Arizona statutes, regulations, insurance
policies, endorsements and current appellate authority should
be verified before legal reliance.
