Is Uninsured Motorist Coverage Required in Arizona?
A serious car accident in Arizona can create immediate financial pressure. Medical bills, lost income, vehicle damage, and long-term suffering can follow within days. But what happens if the other driver has no insurance, or not enough insurance coverage to pay for your injuries?
That is where uninsured motorist coverage and underinsured motorist coverage become critical. Understanding whether uninsured motorist coverage is required in Arizona, and how it works under Arizona law, can protect you from significant financial risk.
According to the Insurance Information Institute, approximately 12 to 13 percent of Arizona drivers are uninsured. That uninsured rate means roughly one out of every eight drivers may have no insurance at all. If you are injured in a crash involving an uninsured or underinsured driver, your financial recovery may depend entirely on your own insurance policy.
Arizona Law: Is Uninsured Motorist Coverage Required?
Many Arizona drivers ask: is uninsured motorist coverage required in Arizona?
The short answer is no.
Under Arizona law, uninsured motorist coverage is not required to operate a motor vehicle. However, insurers must offer it.
Arizona Revised Statutes § 20-259.01 requires every insurer issuing motor vehicle liability policies to offer uninsured motorist and underinsured motorist coverage to policyholders. You can review the statute directly through the Arizona State Legislature.
This law creates what is known as the “offer-and-rejection” rule:
- Your insurer must offer uninsured motorist insurance and UIM coverage.
- You may reject uninsured motorist coverage.
- If you choose to reject uninsured motorist coverage, you must do so in writing.
In other words, uninsured motorist coverage is optional unless waived in writing.
If you reject uninsured motorist coverage and are later injured by an uninsured driver, your ability to recover compensation from your own insurer may be significantly limited, depending on the terms of your policy and any other available coverage.
Given Arizona’s uninsured driver rate, many drivers choose to carry uninsured and underinsured motorist coverage for additional injury protection. The right coverage depends on your specific circumstances and policy options.
What Uninsured And Underinsured Motorist Insurance Covers
Uninsured Motorist Bodily Injury Coverage
Uninsured motorist bodily injury coverage, often called UMBI, provides financial protection when a negligent uninsured driver causes a crash.
This coverage typically pays for:
- Medical bills
- Lost wages and lost income
- Pain and suffering
- Other bodily injury losses
Uninsured motorist coverage is a claim against your own insurer. It is triggered when the other driver has no insurance, or when a hit-and-run driver cannot be identified.
Under Arizona law, hit-and-run drivers are legally treated as uninsured motorists for bodily injury claims, particularly when physical contact occurred.
UM coverage typically does not cover property damage unless you specifically purchase uninsured motorist property damage coverage or rely on collision coverage.
The minimum liability limits commonly offered for UM coverage in Arizona mirror state minimum liability limits: $25,000 per person and $50,000 per accident.
Underinsured Motorist Coverage
Underinsured motorist coverage applies when the other driver has liability insurance, but not enough insurance to pay for your injury.
For example:
- The other driver carries minimum liability limits of 25/50.
- Your medical bills alone exceed $60,000.
- After their policy limits are paid, you still have uncompensated losses.
In that situation, UIM coverage allows you to recover additional compensation from your own insurance company, up to your policy limits.
An uninsured motorist has no insurance at all. An underinsured motorist has some coverage, but not enough insurance to fully compensate victims.
UIM coverage essentially “kicks in” when the other driver’s insurance company reaches its policy limits.
Liability Coverage Versus Uninsured Motorist Coverage
Arizona law requires all drivers to carry liability insurance to legally operate a motor vehicle. The minimum limits in Arizona are 25/50/15, as confirmed by the Arizona Department of Insurance and Financial Institutions.
Liability coverage pays for injuries and property damage you cause to others when you are at fault in an accident.
Here is the key difference:
- Liability insurance protects other people when you cause the accident.
- Uninsured motorist coverage protects you when the other driver causes the accident and has no insurance.
If you are at fault, your liability insurance pays the injured person.
If the other driver is at fault and uninsured, your uninsured motorist coverage may pay your damages.
This difference becomes critical in serious injury cases where victims need to recover damages beyond basic policy limits.
Medical Payments Coverage And Car Accident Injuries
Medical payments coverage, often called MedPay, is optional insurance coverage that helps pay medical bills after a crash, regardless of fault.
MedPay typically covers:
- Emergency room visits
- Ambulance services
- Surgery
- X-rays
- Follow-up care
Unlike uninsured motorist coverage, medical payments coverage does not require the other driver to be uninsured.
MedPay can be especially helpful if you face immediate medical bills before a liability or UM claim is resolved. It may provide early protection while your legal process unfolds.
Arizona drivers with high deductibles or limited health insurance may consider adding medical payments coverage to reduce financial strain after an injury.
Collision, Full Coverage, And Insurance Policy Choices
Collision coverage pays for vehicle damage to your own vehicle after a collision, regardless of fault.
When consumers refer to “full coverage,” they usually mean a combination of:
- Liability insurance
- Collision coverage
- Comprehensive coverage
- Often uninsured or underinsured motorist coverage
However, “full coverage” is not a legal term. You must review your declarations page to confirm what your insurance policy actually includes.
Arizona drivers should consider matching their UM/UIM limits to their liability limits to ensure adequate protection. Many people unknowingly carry high liability limits but low uninsured motorist coverage limits.
How Arizona Drivers Should Choose Insurance Coverage
Choosing proper insurance coverage requires assessing:
- Your driving patterns
- Your financial risk tolerance
- Your exposure to uninsured drivers
- Your family’s dependency on your income
Given Arizona’s uninsured rate, many drivers choose to carry uninsured motorist coverage for additional injury protection. The appropriate coverage depends on your individual circumstances and policy options.
Before you reject uninsured motorist coverage, verify your policy language carefully. Make sure you understand the risk of facing an uninsured or underinsured driver with no safety net.
Also note that certain commercial vehicles, including taxis and limousines, are required to carry higher UM coverage limits, often between $250,000 and $300,000.
Comparative Negligence And Its Effect On UM Claims
Arizona follows a pure comparative negligence system under A.R.S. § 12-2505, which you can review via the Arizona State Legislature.
Under comparative negligence:
- Each person involved in an accident is assigned a percentage of fault.
- Your recovery is reduced by your share of fault.
If you are found 20 percent at fault, your compensation is reduced by 20 percent.
This rule applies to uninsured motorist claims as well. Even though you are filing a claim with your own insurance company, your insurer may argue you were partially at fault.
Gather evidence early to minimize assigned fault:
- Police report and incident number
- Photos of the scene
- Verification of the other driver’s uninsured status
- Witness statements
Evidence, Documentation, And Motor Vehicle Proofs
If you are involved in a crash with an uninsured driver, collect:
- Police report confirming uninsured status
- Insurance verification or written confirmation from the driver’s insurance company
- Photos of vehicle damage and injury
- Medical documentation
- Proof of lost wages
Proof of uninsured status can include written confirmation from the Department of Transportation or carrier denial letters.
Organizing documentation strengthens your uninsured motorist claim and helps prevent disputes with your insurer.
Legal Process: Filing UM Claims, Arbitration, And Litigation
How To Start An Uninsured Motorist Claim
To file a UM claim:
- Open a claim with your own insurance company promptly.
- Request a copy of your declarations page and full insurance policy.
- Provide written notice of your intent to pursue uninsured motorist coverage.
Arizona drivers generally have two years to sue an at-fault driver under A.R.S. § 12-542, which is available through the Arizona State Legislature.
For uninsured motorist claims, you must notify your insurer in writing within three years of the accident date.
Missing these deadlines may significantly limit or prevent recovery, depending on the specific facts and applicable law.
When Arbitration Or Lawsuit Applies
Many uninsured motorist insurance policies include arbitration clauses. This means disputes about fault or damages may go to arbitration rather than court.
However, litigation may still be necessary in certain cases.
Preparing expert medical proof, documentation of suffering, and wage loss evidence is critical when pursuing compensation through arbitration or lawsuit.
Common Insurance Company Tactics And Responses
Like any business, insurance companies evaluate claims carefully and may dispute aspects of fault or damages.
Common tactics include:
- Low settlement offers
- Disputing severity of injury
- Assigning higher comparative negligence percentages
- Requesting recorded statements
Avoid giving recorded statements without legal counsel. Keep communications organized and in writing.
If a dispute arises regarding coverage or valuation, legal options may be available to help resolve the matter, which could include negotiation, arbitration, or litigation depending on the circumstances.
Special Situations: Hit-and-Run, ATVs, And Motor Vehicle Types
In Arizona, hit-and-run drivers are treated as uninsured motorists for bodily injury claims, particularly when physical contact occurred.
However, some insurance policies exclude certain motor vehicle types, such as ATVs or off-road vehicles.
Review your policy definitions carefully to understand what qualifies as a covered vehicle.
Uninsured motorist property damage claims may require identification of the other driver.
Practical Checklist For Reviewing Your Insurance Policy
Before your next policy renewal, review:
- Whether uninsured motorist coverage was offered
- Whether you signed a written rejection
- Your current UM/UIM policy limits
- Whether limits match your liability limits
- Whether MedPay and collision coverage are included
- Any recent life changes requiring higher coverage
Updating insurance coverage after major life changes is essential for proper protection.
