Arizona’s rental car insurance laws require the rental company to carry baseline liability coverage on every vehicle it puts on the road, but the fine print of nearly every rental agreement shifts that coverage into the excess position, which means your personal auto policy pays first if you cause a crash. If you don’t carry personal auto insurance, the liability policy you buy at the counter becomes your primary protection, and the company’s statutory minimum sits behind it as a backstop for third parties.
The controlling statute is A.R.S. § 28-2166. It sets what the company must carry, how coverage priority works, and what happens when a company skips the rules. A few other provisions fill in the picture: § 28-4009 sets the general driving minimums, § 20-331 regulates what rental agents can sell you, and § 28-4135 spells out the penalties for driving uninsured.
What the Rental Company Must Carry
The Arizona Department of Transportation cannot register or allow the rental of a vehicle unless the company has obtained public liability insurance or qualified as a self-insurer. The company’s policy must provide renters at least:
- $15,000 per person for bodily injury or death
- $30,000 per accident for bodily injury or death of two or more people
- $10,000 for property damage
A company that rents without meeting these requirements is jointly and severally liable with the renter for damages caused by the renter’s negligence, and the violation is a class 2 misdemeanor.1Arizona Legislature. Arizona Revised Statutes 28-2166 – Registration of Vehicle Rented Without a Driver; Liability Insurance; Joint Liability; Violation; Classification; Definition
These rental-specific floors are lower than Arizona’s general driving minimums. For policies issued or renewed since July 1, 2020, every driver on Arizona roads must be backed by liability coverage of $25,000 per person, $50,000 per accident, and $15,000 for property damage.2Arizona Legislature. Arizona Code 28-4009 – Motor Vehicle Liability Policy Requirements If you drive a rental protected only by the § 28-2166 floor, there is a real gap between what the company’s policy covers and what the state’s financial responsibility law expects of you. Most major rental companies carry well above the statutory minimum, but the law allows the narrower floor.
Whose Insurance Pays First
The default rule under § 28-2166(C) is that the rental company’s liability insurance is primary for damages caused by the renter. Your personal auto policy only pays 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 lets the company 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 must 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 companies include that language as a matter of course, which is why most renters find their own auto insurance on the hook first.
If you bought liability coverage from the rental company at the counter, that purchased policy applies and must be exhausted before any other coverage.1Arizona Legislature. Arizona Revised Statutes 28-2166 – Registration of Vehicle Rented Without a Driver; Liability Insurance; Joint Liability; Violation; Classification; Definition No matter how priority is arranged among the policies, the rental company still has to respond to third-party claims up to the § 28-2166(B) minimums. Someone you injure in a rental always has a source of recovery, even if you personally carry no insurance.
What to Check Before You Sign
Read the disclosure section of the rental agreement. If the statutory disclaimer is there, assume your own auto policy is first in line and call your insurer before the trip to confirm two things: that your policy covers rental vehicles, and that it extends to the state where you’ll be driving. If your policy excludes rentals, or if you don’t carry personal auto insurance at all, the liability coverage sold at the counter is what stands between you and personal exposure above the company’s statutory floor.
Arizona’s Department of Insurance and Financial Institutions regulates the people who sell these products at rental counters. Under A.R.S. § 20-331, rental car agents can offer supplemental liability insurance, including uninsured and underinsured motorist coverage.3Arizona Legislature. Arizona Code 20-331 – Rental Car Agents; Definitions
Credit Card Coverage
Some credit cards include collision or loss damage coverage when you use the card to pay for the rental. Most of this coverage is secondary to your personal auto policy and applies only to physical damage to the rental vehicle itself, not liability for injuries to other people. A few premium cards offer primary coverage, which means the card’s benefit pays before your personal insurer gets involved. Credit card coverage does not replace the liability insurance Arizona requires; it works alongside an auto policy, not instead of one.
Damage Waivers Are Not Insurance
The Collision Damage Waiver or Loss Damage Waiver offered at the counter is a contract, not an insurance policy. In it, the rental company agrees not to hold you financially responsible for damage to the rental car. A waiver does nothing for liability to other drivers, passengers, or pedestrians you injure.
If your personal auto policy already includes collision and comprehensive coverage, that coverage often extends to a rental car, minus your deductible, which can make the waiver redundant. Check your declarations page before you travel.
Waivers also come with exclusions that void them entirely. Common triggers include driving under the influence, driving off paved roads, letting an unauthorized driver take the wheel, or using the car outside the geographic area the rental agreement allows. The exact terms are contractual and vary by company, so read the waiver document rather than relying on what the agent describes.
Peer-to-Peer Car Sharing
Rentals through platforms like Turo follow a separate set of rules. Arizona requires the sharing 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.
During each sharing period, the platform’s coverage is primary and does not wait on a personal auto insurer to deny a claim first. That is a sharper rule than traditional rentals, where the company can push its own coverage into the excess position through the rental agreement. Arizona also prohibits an insurer from canceling your personal auto policy solely because you listed your car on a sharing platform, though the insurer can act if you misrepresent how the vehicle is being used.
If you’re the owner listing a car, confirm with your insurer that your personal policy won’t be voided during sharing periods. Standard personal auto policies commonly exclude commercial use. The platform’s built-in coverage is designed to fill the gap, but mismatches between the platform policy and your personal policy can still leave you exposed.
Penalties for Driving the Rental Uninsured
Driving without financial responsibility is a civil violation under A.R.S. § 28-4135, and the penalties apply whether the car is yours or rented:
- First offense: a minimum $500 civil penalty and a three-month suspension of driving privileges.
- Second offense within 36 months: a minimum $750 civil penalty and a six-month suspension of both the driver’s license and the vehicle’s registration.
- Third or subsequent offense within 36 months: a minimum $1,000 civil penalty, a one-year suspension, and a requirement to file proof of financial responsibility before reinstatement.
These apply to anyone driving on Arizona roads.4Arizona Legislature. Arizona Code 28-4135 – Motor Vehicle Financial Responsibility Requirement; Civil Penalties; Restricted Driving Privilege; Evidence at Hearing In a rental scenario, registration suspension isn’t the risk (the car isn’t yours), but the fines and license suspension are.
After an Accident in a Rental Car
The basics are the same as any crash. Make sure everyone is safe. Call 911 if anyone is hurt. Exchange contact and insurance information with the other driver, and collect license plate numbers, vehicle descriptions, and witness details. Photograph the damage, the position of the vehicles, and the scene.
Then call the rental company. Most agreements include an emergency number in the glove box or printed on the contract, and the company will have you complete its own incident report. After that, notify your personal auto insurer to open a claim if your policy is providing primary coverage, and report the incident to any supplemental liability or damage waiver provider identified in the rental paperwork.
Keep your statements factual. Casual apologies at the scene can resurface later when insurers are sorting out fault. Ask if the other party is okay, exchange information, and leave opinions about who caused the crash out of the conversation.
