The age requirement to rent a car in Arizona is set by each rental company, not by state law. Most national brands require you to be at least 21, a few local agencies in Phoenix and Tucson will rent to 20-year-olds, and certain vehicle categories push the floor up to 25. Renters between 21 and 24 pay a daily young-driver surcharge that averages around $25 at the major brands.
Minimum Age at the Major Rental Companies
No Arizona statute sets a minimum age for renting a vehicle, despite a widespread belief that the floor is 18. The practical minimum comes from company policy. Enterprise rents to drivers 21 and older in most locations. Some smaller local agencies in the Phoenix and Tucson areas will rent to drivers as young as 20. A narrow military exception can bring the age down to 18, but that isn’t a general policy.
For some vehicle categories, the minimum jumps to 25 no matter which company you use. Luxury cars, high-performance vehicles, and large passenger vans almost always carry that higher threshold. Enterprise specifically requires renters to be at least 25 for 12- and 15-passenger vans, and those vans cannot be used to transport children in 12th grade or younger (other than family members) for school-related events.1Enterprise Rent-A-Car.

There is no upper cap. No major U.S. rental company imposes a maximum age limit, so older drivers face no age-based restriction in Arizona.
The Young Renter Surcharge Between 21 and 24
If you’re between 21 and 24, expect a daily “young renter fee” at nearly every national brand. Hertz charges $25 per day and describes that as below the industry average.2Hertz. Under 25 Car Rental Enterprise averages roughly $25 per day, though the amount can be higher or lower depending on the location.3Enterprise Rent-A-Car. What Are Your Age Requirements for Renting On a week-long rental, that surcharge alone can add $175 or more to the total, and it often doesn’t appear in the initial online quote.
Who Can Skip the Surcharge
Active-duty military members traveling on government orders get the most generous exception. Under the U.S. Government Rental Car Program, drivers ages 18 through 20 can rent from participating companies, and the underage fee is reimbursable through the Joint Travel Regulations.4Defense Travel Management Office. Rental Car Program Government travelers also receive Loss Damage Waiver and liability coverage at no extra cost.
Outside the military context, some corporate rental agreements and membership organizations negotiate surcharge waivers. If your employer has a business account with a major brand, check whether underage fees are included in the negotiated rate. A few companies also waive the fee for members of AAA or USAA, though these exceptions change frequently and aren’t guaranteed at every location.
What You Need at the Counter
Every renter must present a valid, original driver’s license. Photocopies and phone images won’t work. If your license was issued outside the United States, you can legally drive in Arizona with it, but the Arizona Department of Transportation recommends carrying an International Driving Permit alongside it, especially if your license isn’t printed in English.5Department of Transportation. What Is Needed for a Person from Another Country to Drive in Arizona Rental companies may have stricter documentation rules than state law, so confirm with the agency before you arrive.
Paying With Credit Versus Debit
A major credit card in the renter’s name is the simplest way to handle the transaction. The company places a hold for the estimated rental charges plus a security deposit, and that hold drops off your account after you return the vehicle.
Debit cards create more friction. At airport locations, Alamo accepts a debit card only if you also present a ticketed return travel itinerary.6Alamo Rent a Car. Renting a Car with a Debit Card Without that itinerary, you’ll need a credit card and a deposit hold between $300 and $400 depending on location and vehicle class. Dollar goes further and runs a credit check on debit card customers; an unfavorable check means the rental is declined.7Dollar Rent a Car.

Adding Another Driver
Anyone else who will drive the rental must be listed on the agreement. The additional driver needs a valid license and typically has to meet the same minimum age as the primary renter. If they’re under 25, the young renter surcharge applies to them too.
Budget charges $13 per day per additional driver in most states, capped at $65 per rental.8Budget Rent a Car. Renting a Car for Someone Else – Additional Driver FAQs Avis waives the fee for a spouse or life partner as long as they have a valid license and are at least 25, and fellow employees on business trips drive free of the additional driver charge under Avis business accounts.9Avis Rent a Car. Can I Add Another Driver to My Car Rental
Handing the keys to someone not listed on the agreement is expensive if anything goes wrong. Every coverage option you purchased from the rental company, including the Collision Damage Waiver, is voided when an unauthorized driver is behind the wheel. The unauthorized driver’s own personal auto insurance becomes the only source of coverage. If that person carries none, you as the renter may be personally liable for repairs, medical bills, and third-party claims.
Insurance You Actually Need
Arizona requires liability insurance on every vehicle on its roads, with minimums of $25,000 for one person’s bodily injury, $50,000 for two or more people, and $15,000 for property damage.10Department of Transportation. Insurance Information and Requirements Rental companies offer several add-on products at the counter: a Loss Damage Waiver for the car itself, Supplemental Liability Insurance to raise your liability limits, Personal Accident Insurance for medical costs, and Personal Effects Coverage for belongings inside the vehicle.
Before buying anything, check two things: your personal auto insurance policy and your credit card benefits. Most personal auto policies extend the same collision and liability coverage to rental cars used for personal trips, though they often exclude business use and may not cover “loss of use” fees the rental company charges while the car sits in a repair shop.
Many credit cards include rental car coverage, but the distinction between primary and secondary matters. Primary coverage pays out first after an accident, keeping your personal insurer out of it. Secondary coverage, which is what most cards offer, only kicks in after your personal auto insurance pays its share, covering your deductible and any remaining gaps. If you don’t carry personal auto insurance at all, secondary credit card coverage generally steps into the primary role for collision damage. To activate the benefit, you typically need to pay for the entire rental with that card and decline the rental company’s collision coverage.
Practical Steps for Renters Under 25
The steepest combination of surcharges and restrictions falls on drivers between 21 and 24. A few strategies help. Booking through a corporate or membership discount code, if you have access to one, sometimes zeroes out the young renter fee. Comparing smaller local agencies against national brands is worth the time; local operators occasionally skip the surcharge to stay competitive, especially at off-airport locations around Phoenix and Tucson.
If you’re renting at the airport with a debit card, print your return flight itinerary before you get to the counter. Without it, you may be turned away or asked for a credit card you don’t have. And verify that your personal auto insurance or credit card benefit covers rental vehicles in Arizona before declining the counter products. Saving $15 a day on the waiver and then facing a five-figure liability bill because you had no coverage at all is the worst outcome available.
