Arizona has one of the higher rates of uninsured driving in the country, and the state’s minimum liability limits are low relative to what a serious injury costs.
The combination means a substantial share of significant claims in Phoenix face the same problem: clear fault, real injuries, and nowhere near enough insurance on the other side.
Two Different Coverages
Uninsured motorist coverage applies where the at-fault driver has no insurance, or cannot be identified in a hit-and-run.
Underinsured motorist coverage applies when the driver has insurance, but it is insufficient to cover the damages.
Arizona requires insurers to offer both, and they are included unless the insurer rejects them in writing. Many drivers who think they declined it actually carry it, which is why you should check the declarations page rather than assume.
Minimum Limits Do Not Go Far
Arizona’s required liability limits are modest. A single hospital admission involving surgery, imaging, and a few days of care comfortably exhausts them.
For a catastrophic injury, the shortfall is enormous. A claim genuinely worth several hundred thousand dollars against a driver carrying state minimums has almost nothing available from that driver.
Increasing your own uninsured and underinsured limits is among the cheapest coverage decisions available, and it protects you rather than someone else. Most drivers have never been told that, and carry minimums by default.
Stacking
When a household carries policies on more than one vehicle, or when more than one policy might apply, total available coverage can be considerably larger than a single declarations page suggests.
Whether coverage stacks depends on the policy language and the circumstances. Anti-stacking provisions are common and are not always effective as written.
Reviewing every policy in the household is worthwhile at the outset of a serious claim, and GLG does so before evaluating any offer. Injured people often discover coverage on a spouse’s vehicle or a resident relative’s policy that no one thought to check.
Household Members and Permissive Users
Disputes about who qualifies as a covered person arise more often than people expect.
Resident relative status is the recurring question. A college student living away, a family member temporarily staying elsewhere, or an adult child who recently moved out may or may not qualify, depending on the facts and the policy language.
Permissive use is another. A driver borrowing a vehicle with the owner’s consent is generally covered, and disputes arise when consent is contested or when the use exceeds what was permitted.
These determinations affect whether an entire layer of coverage is available, and they are worth examining rather than accepting a carrier’s initial position.
The Notice Requirement
This is the most damaging trap for someone handling a claim without advice.
Before accepting a settlement from the at-fault driver’s insurer, you generally must notify your own underinsured carrier and allow it to protect its subrogation interest. Settling and signing a release without doing so can forfeit your underinsured coverage entirely.
This happens constantly. An adjuster offers policy limits; it looks like a good outcome, the release gets signed, and the far larger underinsured claim disappears.
The notification is straightforward. The consequence of skipping it is not.
Bad Faith Claims Handling
Arizona has a well-developed body of law recognizing that an insurer owes a duty of good faith and fair dealing to its own insured, and that duty is enforceable.
A carrier that denies a valid claim without a reasonable basis, delays unreasonably, or fails to investigate properly can face liability beyond the policy amount, including punitive damages in appropriate cases.
This matters most in uninsured and underinsured claims, because those are made against your own carrier. The relationship shifts from customer to claimant, and carriers sometimes treat it accordingly.
Documenting communications, keeping records of what was submitted and when, and noting unexplained delays preserve the ability to raise the issue if necessary.
Who Is Covered
Coverage extends further than most people realize.
Policies typically cover the named insured, resident relatives in the household, and anyone permitted to occupy a covered vehicle. A passenger injured in a friend’s car may have access to both their own household policy and the vehicle’s policy.
Pedestrians and cyclists struck by a vehicle can also access uninsured and underinsured motorist coverage under their own auto policy, even if none of their vehicles were involved. That is among the most commonly missed sources of recovery in Arizona.
Motorcyclists should confirm what their motorcycle policy includes, since coverage decisions made when the policy was written often don’t reflect what the rider assumed.
Uninsured Driving Is Common in Arizona
Arizona consistently reports one of the higher uninsured driver rates in the country, and many insured drivers carry only the state minimum.
That reality is the practical argument for carrying meaningful coverage yourself. The protection you buy is more reliable than the protection the law requires of everyone else.
It also means an injured person should assume from the outset that the at-fault driver’s coverage may be inadequate, and investigate their own available coverage in parallel rather than waiting to discover the shortfall months later.
Hit-and-Run Claims
Where the at-fault driver cannot be identified, uninsured coverage responds, and carriers apply additional scrutiny because a phantom vehicle is difficult to disprove.
Prompt reporting to law enforcement is generally required, and delays can raise questions about the claim. Some policies require physical contact with the unidentified vehicle, which excludes scenarios in which a driver was forced off the road without being struck.
Independent witnesses matter more here than in almost any other claim. Camera canvassing is also productive and time-sensitive, since residential and business footage is overwritten within days.
Medical Payments Coverage
Separate from uninsured and underinsured coverage, many Arizona policies include medical payments coverage, which pays medical expenses regardless of fault up to a limit.
It is inexpensive, it pays quickly, and it fills the gap while a liability claim is developed. Many drivers carry it without realizing it and never make a claim.
Health insurers and providers may assert reimbursement rights against any eventual recovery, and coordinating those interests is a substantial part of determining what an injured person actually receives.
Rental Vehicles and Commercial Coverage
Coverage questions become more complex when the at-fault vehicle is not the driver’s own.
A rental vehicle may carry its own coverage, and the renter’s personal policy may extend to it. If a driver was working at the time, an employer’s commercial policy may respond, and those limits are usually far higher than those of personal auto coverage.
Establishing whether the at-fault driver was in the course of employment is therefore worth investigating rather than assuming. A delivery, a work errand, or travel between job sites can bring commercial coverage into a claim that would otherwise be subject to minimum limits.
It Is Still an Adversarial Claim
A claim against your own insurer is not a cooperative process, though people expect it to be.
Your carrier will investigate fault, dispute the extent of injuries, and require you to prove the claim as any insurer would. Comparative fault applies in the same way, which means the same arguments about your conduct arise.
Policies also impose obligations — prompt notice, cooperation, examination under oath if requested, medical authorizations. Failing to do so can jeopardize coverage regardless of the merits.
Arizona recognizes that an insurer owes a duty of good faith to its own insured, and a carrier that denies a valid claim without a reasonable basis faces exposure beyond the policy limits.
If an uninsured or underinsured driver hit you in Phoenix, call GLG before you sign anything from any insurer, including your own.
