Arizona rental car insurance laws sit in two statutes that decide almost everything about your coverage: A.R.S. § 28-2166 requires the rental company to carry liability insurance for renters, and the same statute lets the company push its coverage into second position through a disclosure in your rental agreement. In practice, that means the company’s policy is technically primary by default, but nearly every major rental contract contains the statutory language that flips your personal auto policy to the front of the line.
What the Rental Company Must Carry
Arizona won’t let a rental company register or rent out a vehicle unless it has liability insurance or has qualified as a self-insurer. The floor set by A.R.S. § 28-2166 is:
- $15,000 per person for bodily injury or death
- $30,000 per accident when more than one person is injured or killed
- $10,000 for property damage in a single accident
These figures apply to the coverage the company itself provides to renters.1Arizona Legislature. Arizona Revised Statutes 28-2166 – Registration of Vehicle Rented Without a Driver; Liability Insurance; Joint Liability; Violation; Classification; Definition They are lower than the general driving minimums Arizona sets for all motorists under A.R.S. § 28-4009, which are 25/50/15 for policies issued or renewed since July 1, 2020.2Arizona Legislature. Arizona Code 28-4009 – Motor Vehicle Liability Policy Requirements Most large rental companies carry more than the § 28-2166 minimum, but the statute allows a narrower floor for the rental-provided layer.
A rental company that fails to comply becomes jointly and severally liable with the renter for damage caused by the renter’s negligence, and non-compliance is a class 2 misdemeanor.1Arizona Legislature.

Whose Policy Pays First
The default under A.R.S. § 28-2166(C) is that the rental company’s liability insurance is primary for damages caused by a renter. Your personal auto policy would only pay after the company’s coverage is exhausted.1Arizona Legislature. Arizona Revised Statutes 28-2166 – Registration of Vehicle Rented Without a Driver; Liability Insurance; Joint Liability; Violation; Classification; Definition
The statute then gives the company a way to reverse that order. If the rental agreement includes a specific disclosure stating that the owner does not extend its financial responsibility or public liability coverage to the renter, the company’s insurance drops from primary to excess. The disclosure has to appear in at least ten-point bold type in the rental agreement, in a master agreement kept with the renter, or conspicuously during an online reservation. The major rental brands routinely include this language, so most renters find that their own personal auto policy is on the hook first.
One exception matters. If you buy liability insurance directly from the rental company at the counter, that purchased coverage applies and must be exhausted before any other applicable insurance.1Arizona Legislature. Arizona Revised Statutes 28-2166 – Registration of Vehicle Rented Without a Driver; Liability Insurance; Joint Liability; Violation; Classification; Definition And regardless of how priority is arranged, the rental company still has to respond to third-party claims up to the § 28-2166(B) minimums, so an injured victim always has a source of recovery.
What to Check Before You Sign
Look at the rental agreement’s liability section. If it contains the statutory disclaimer, assume your personal auto policy is primary. Call your insurer before the trip to confirm your policy covers rental vehicles and extends to Arizona (or to wherever you’re driving). If you don’t carry personal auto insurance, or your policy excludes rentals, the company’s baseline coverage plus any supplemental liability you buy at the counter will be your only protection.
Damage Waivers and Supplemental Liability
At the counter you’ll be offered a Collision Damage Waiver (CDW) or Loss Damage Waiver (LDW). These are not insurance. They are contract terms under which the rental company agrees not to hold you financially responsible for damage to the rental car itself. Arizona’s Department of Insurance and Financial Institutions licenses the counter agents who sell these products under A.R.S. § 20-331, which also authorizes them to offer supplemental liability insurance, including uninsured and underinsured motorist coverage.3Arizona Legislature. Arizona Code 20-331 – Rental Car Agents; Definitions
A damage waiver covers only the rental vehicle. It does nothing for injuries or damage you cause to other people. If your personal auto policy already includes collision and comprehensive coverage, that coverage often extends to rentals, minus your deductible, which can make the waiver redundant. Confirm this with your insurer, not with the counter agent.
Waivers also come with exclusions that void them entirely: driving under the influence, driving off paved roads, letting an unauthorized driver take the wheel, or taking the car outside the geographic area allowed by the agreement. These are contractual and vary by company. Read the waiver itself, not just the signature line.
What Credit Card Coverage Actually Does
Some credit cards include rental car benefits, but the typical card covers only physical damage to the rental vehicle and pays secondary to your personal auto policy. A few premium cards offer primary coverage for that same physical-damage risk. No credit card benefit satisfies Arizona’s liability insurance requirement, and none of them cover injuries you cause to other people. Card coverage works as a supplement to auto insurance, not a substitute.
Penalties for Driving a Rental Without Insurance
Arizona’s financial responsibility law applies to anyone on the road, including renters. Under A.R.S. § 28-4135, driving without meeting the state’s insurance requirements is a civil violation with escalating penalties:
- First offense: at least a $500 civil penalty and a three-month license suspension
- Second offense within 36 months: at least $750 and a six-month suspension of both license and vehicle registration
- Third or subsequent offense within 36 months: at least $1,000, a one-year suspension, and a requirement to file proof of financial responsibility before reinstatement4Arizona Legislature. Arizona Code 28-4135 – Motor Vehicle Financial Responsibility Requirement; Civil Penalties; Restricted Driving Privilege; Evidence at Hearing
The registration suspension is unlikely to matter in a rental scenario because the car isn’t yours, but the fines and license suspension apply the same way they would in your own vehicle.5Arizona Department of Transportation. Insurance Information and Requirements
Peer-to-Peer Rentals Are a Different Category
If you’re renting through Turo or a similar platform, the rules above don’t fully control. Arizona has separate legislation for peer-to-peer car sharing that requires the platform to ensure both the vehicle owner and the driver carry liability insurance meeting at least the 15/30/10 minimums. That insurance can be maintained by the owner, the driver, the platform, or some combination. The platform’s coverage is primary during each sharing period and doesn’t wait for a personal auto insurer to deny a claim first. An insurer also cannot cancel your personal auto policy solely because you listed your car on a sharing platform, though misrepresenting how the car is used is a different matter.
If you’re the owner listing a vehicle, be aware that standard personal auto policies often exclude coverage during commercial use. Check with your insurer so you understand what the platform’s policy covers and what it doesn’t.
After an Accident in a Rental
The steps look like any other collision, with a few additions. Get everyone to safety and call 911 if anyone is hurt. Exchange contact and insurance information with the other driver, note license plates and vehicle descriptions, and get contact information for any witnesses. Photograph the damage, the vehicle positions, and the surrounding scene.
Then call the rental company. The emergency number is usually in the glove box or printed on the rental contract, and the company will have you fill out its own incident report. Notify your personal auto insurer if your policy is providing primary coverage, and notify any supplemental liability provider or damage waiver administrator listed in your rental paperwork.
Don’t admit fault at the scene, even in passing. Casual statements can resurface later when insurers are working out liability. Be polite, check on the other party, and stick to exchanging information.
