A crash in a borrowed car can involve the owner’s insurance, the driver’s insurance and coverage for the injured occupants. Permission matters, but permission alone does not answer every coverage question. An exclusion, the purpose of the trip or the relationship between the people involved can change the analysis.
This guide explains coverage, payment order, and policy exclusions in an Arizona borrowed-car accident claim. If you want the bigger picture, see how Arizona accident claims work.
The owner’s liability policy is often the starting point. Under A.R.S. § 28-4009(A)(2), an owner’s liability policy must cover the named insured and people using the insured vehicle with express or implied permission, subject to the statute. Coverage still requires review of the policy, endorsements and facts. Liability insurance addresses covered harm to others; it does not automatically pay the borrowing driver’s own injuries or damage to the borrowed car.

A.R.S. § 28-4010(B) generally makes the policy describing or rating the vehicle as owned primary when two or more valid, collectible liability policies cover the same vehicle. Other applicable policies are excess. That priority rule does not create coverage under a borrower’s policy that otherwise excludes the event. Special rules apply to certain motor vehicle businesses.
Separate three questions: does a policy cover this driver and use, which covered policy pays first, and what limits remain? A denial under one policy does not resolve the other two questions.
An owner’s policy can cover an occasional borrower who is not named on the declarations page. The permission provision in A.R.S. § 28-4009 is the starting point. It does not mean that every relative, roommate or person holding the keys has the same coverage.
Express permission can be spoken or written. Implied permission depends on conduct and the relationship between the owner and driver. Save messages, prior arrangements and accounts from people who heard permission given. A history of borrowing can be relevant, but no particular number of previous trips automatically proves permission for this trip.
For policies issued or renewed on or after July 1, 2020, A.R.S. § 28-4009 generally requires bodily injury limits of $25,000 per person and $50,000 per accident, plus $15,000 for property damage. These are liability minimums, not a valuation of anyone’s injuries. Multiple injured people may share the per-accident limit. Higher limits or other applicable coverage require verification.
A borrower’s personal auto policy may provide liability coverage for a non-owned vehicle. Read its insured-person definition, non-owned-auto terms, regular-use exclusions and other-insurance clause. If both policies actually cover the collision, the statutory priority rule may place the borrower’s coverage above the owner’s. The word excess describes payment order, not a promise to pay every unpaid dollar.
For example, suppose covered injury damages exceed the owner’s applicable liability limit. The borrower’s insurer may owe additional benefits only if its policy covers the driver, vehicle and trip. If no second policy applies, the unpaid amount does not become insurance coverage merely because it exceeds the first limit. Personal liability and practical collectibility are separate issues.
One important caveat: excess coverage doesn’t automatically mean broader coverage. If the borrower’s policy has its own exclusions, those exclusions still apply when it’s acting as excess. Read both policies. Coverage always turns on the specific policy language and the facts.
Household membership matters because policies define named insureds, family members, residents and other insured people differently. Someone can qualify for liability coverage without qualifying for every first-party benefit. A family member who lives elsewhere may have a different status from a resident relative.
Check each coverage section independently. Liability, medical payments and uninsured or underinsured motorist coverage can use different definitions and exclusions. Do not assume a resident relative has every benefit shown on the declarations page, or that an occasional permissive driver has none.
Common scenarios:
Useful records can include the application, declarations, driver lists, residence documents and communications with the agent. Explain the actual living arrangement accurately. If an insurer disputes residence, ask for the relevant policy language and the facts supporting its position. A disagreement is not, by itself, proof of bad faith.
When permission is genuinely absent, the owner’s permissive-use provision may not cover the driver. The coverage question requires the policy and facts, including who could grant permission and whether it was express or implied. A stolen car and a family disagreement about borrowing are not necessarily the same situation.
Disputes can involve the scope of permission rather than whether the owner ever handed over the keys. Keep the original messages and provide a factual timeline instead of trying to reconstruct a convenient explanation later.
Request a written denial identifying the factual and policy grounds. A lawyer can assess whether the insurer applied the law and contract correctly. A third-party injured claimant generally does not acquire the insured’s contractual rights merely by making a claim against that policy. Do not label a disputed denial bad faith without identifying the claimant’s legal rights and the actual conduct.
A.R.S. § 28-4009(A)(3) permits a written agreement between the named insured and insurer excluding a specifically named person from coverage. The statute addresses continuation through renewals and written reinstatement. Obtain the actual agreement and review its application to the coverage being claimed. Permission to borrow does not automatically undo a valid named-driver exclusion.
An exclusion is a document to verify, not an assumption based on a driver’s record. Review:
A liability exclusion can leave a serious coverage gap. It does not establish, without further review, what every other auto or umbrella policy does. Umbrella coverage has its own insured-person definitions, exclusions and underlying-insurance requirements. Do not assume a homeowners policy pays an auto injury claim.
The borrower’s own policy must be examined independently. If it covers the event, priority and payment issues follow from the applicable policies and law. If it excludes the driver’s use of this vehicle, the owner’s denial does not automatically convert that exclusion into coverage.
Using a borrowed car for work can raise additional questions. A personal policy may distinguish ordinary errands, transportation of goods for a fee, passenger transportation and other business uses. The label work errand does not establish a universal exclusion. Read the specific terms and identify what the driver was doing at the time.
Examples that warrant a separate coverage review include:
Preserve app status, trip receipts, the driver agreement and employer records where relevant. Personal insurance, an employer’s policy and platform coverage may have different triggers. Whether the driver was available, had accepted a trip or was transporting someone can matter. Food delivery and passenger rideshare are not interchangeable insurance arrangements.
Before borrowing a vehicle for paid work, ask the insurer or agent about that exact activity and vehicle. Obtain written confirmation of applicable coverage or the needed endorsement. After a crash, preserve the policies effective on that date; buying coverage later does not establish coverage for the earlier event.
Liability coverage for injuries the borrower causes to someone else is different from coverage for the borrower’s own injuries. Identify the responsible driver and then review each possible source of payment. Keep a ledger so medical payments, health benefits and settlements are not confused or counted twice.
Medical payments coverage: If purchased and applicable, MedPay can pay eligible crash-related medical expenses without requiring proof that another driver was at fault. The covered-person definition, expense requirements, payment period and dollar limit come from the policy. Permission alone does not establish eligibility.
Uninsured or underinsured motorist coverage: A.R.S. § 20-259.01 governs Arizona UM/UIM coverage. A borrower may qualify under the owner’s policy as an insured occupant, but the purchased coverage, declarations and terms must be checked. UM and UIM are distinct coverages for bodily injury; they are not substitutes for collision coverage on the car.
Your own UM/UIM coverage: A personal policy may also apply, depending on insured status and terms. Arizona does not impose a blanket rule that every claimant must pick just one policy. Section 20-259.01(H) permits specified anti-stacking limits when one insured purchased multiple policies or coverages on different vehicles. Its wording and notice requirements matter. In State Farm v. Balzan, No. CV-24-0140-PR (Ariz. July 6, 2026), the Supreme Court held that named insureds who jointly procure coverage function as one purchaser for this rule. The relevant question is who obtained the coverage, not merely who funded the premiums. That holding does not resolve every situation involving different purchasers. Such policies require their own analysis under the policy language and applicable law.
Health insurance: Health benefits may cover eligible treatment under the plan’s terms, deductibles and network rules. Some plans or public programs have reimbursement rights after a settlement. Keep benefit statements and identify those rights before estimating the amount that will remain available after bills and reimbursement obligations.

You can report the collision to potentially responsible insurers without accepting any one company’s coverage position. Keep the claim numbers, contact details and dates of each communication. A useful sequence is:
Ask each insurer to identify whether it is disputing fault, insured status, policy coverage or priority. These are different disputes and require different evidence. A lawyer can compare the responses and seek records through available procedures; hiring a lawyer does not guarantee a particular coverage decision.
Arizona generally reduces damages by the claimant’s share of fault under A.R.S. § 12-2505. Fault allocation and available insurance remain separate questions. The statute has exceptions, including intentional, wilful or wanton conduct by the claimant. Evidence of another person’s fault and proof of damages are still necessary.
Negligent entrustment concerns the conduct of the person who supplied or controlled the vehicle. It is distinct from the driver’s careless operation. In Verduzco v. American Valet, No. 1 CA-CV 15-0138 (Ariz. App. June 21, 2016), paragraph 8, quoting Acuna v. Kroack, the court described the required ownership or control, permission, driver incompetence, knowledge, causation and damages. That decision addressed whether allegations could proceed, not a finding that every vehicle lender is liable.
The relevant evidence concerns both the driver’s inability to drive safely and what the supplier knew or should have known. Depending on the facts, an investigation may examine:
An expired license or a prior citation does not automatically prove incompetence, knowledge and causation. Nor does a viable entrustment claim guarantee an additional insurance limit. Coverage for the supplier’s alleged negligence requires separate review of each policy and exclusion.
Preserve communications about lending the car and identify witnesses to the driver’s condition. These records can distinguish an unsupported allegation from a claim grounded in what happened before the keys changed hands.
Subrogation and reimbursement depend on the benefit paid. Section 20-259.01(I) addresses rights after UM payments; it should not be treated as a universal rule for every medical or UIM payment. Identify the payer, coverage and legal basis of any repayment demand.
For auto MedPay, A.R.S. § 20-259.01(J) provides a lien for payments exceeding $5,000, in the amount above that threshold, against specified liability recoveries. It requires fair and equitable compromise. It also sets recording and mailing requirements, including recording within 60 days after a payment exceeding $5,000 and mailing notice within five days after recording. A $5,000 MedPay payment does not itself create a $5,000 lien under this provision.
Health insurers, ERISA plans, Medicare, and AHCCCS all have their own subrogation rules. Don’t sign a release with the at-fault insurer until you know what liens will come out of your net.
The clock matters. Here’s the sequence:
An Arizona injury lawsuit against a private party generally has a two-year limit after accrual under A.R.S. § 12-542. A public-entity or public-employee claim generally requires a proper notice within 180 days after accrual under A.R.S. § 12-821.01, plus a separate lawsuit within one year after accrual under A.R.S. § 12-821. These are separate requirements, not extra time added to the private-party deadline. Identify the claimant, responsible parties and accrual date early. Minority, disability and other exceptions require individual review. A private contractor does not automatically become a public entity because it works on a public road.
UM/UIM claims also have separate written-notice and arbitration or lawsuit rules under A.R.S. § 12-555. An ordinary claim report may not satisfy every requirement. Calendar those dates separately from the lawsuit deadline against the driver.
The owner’s applicable liability policy is generally primary when multiple valid, collectible policies cover the same vehicle under A.R.S. § 28-4010. The borrower’s policy may be excess if it covers the event. A denial or exclusion under the owner’s policy does not automatically create coverage under the borrower’s policy.
It may cover liability while you drive a non-owned car, depending on the policy. Check permission, regular-use restrictions, business-use terms and exclusions. Read the complete policy and endorsements, not just the declarations page. Damage to the borrowed car and your own injuries require separate coverage analysis.
Save evidence of express or implied permission and request the written denial with its policy basis. A lawyer can evaluate the applicable coverage and proof requirements. Do not assume every denial is valid, or that a disputed denial automatically gives an injured third party a bad-faith claim against the insurer.
Possibly, if you qualify as an insured under the purchased coverage and the loss meets its terms. Your own UM/UIM policy may also matter. Section 20-259.01(H) allows certain anti-stacking provisions; it does not categorically prohibit every recovery involving more than one policy.
The claim requires more than ownership or permission: the driver’s incompetence, the supplier’s knowledge, causation and damages matter. A valid claim against the supplier does not itself guarantee additional insurance coverage.
Identify the actual activity and app or trip status. Personal, employer and platform policies may have different terms. Passenger rideshare and food delivery are different arrangements. Do not assume the owner’s personal policy covers paid use or that a platform necessarily fills every gap.
