Arizona rental car companies require you to be at least 18 years old, but most charge extra fees if you're under 25

You can rent a car in Arizona at 18 with a valid driver's license, but nearly every major rental company—Enterprise, Hertz, Budget, Avis, National, and others—adds a daily surcharge called a young driver fee if you're under 25. This fee typically ranges from $15 to $30 per day, though the exact amount varies by company and location. Some smaller or local rental agencies may have different age policies, so it's worth calling ahead if you're under 25 and want to avoid the extra cost.

The reason for the age restriction and fees is insurance risk. Drivers under 25 have higher accident rates statistically, and rental companies price that risk into their fees. If you're 25 or older, you'll avoid the young driver surcharge entirely at most companies, though a few still charge it up to age 30.

Key Takeaways

  • You must be at least 18 years old and have a valid driver's license to rent a car in Arizona; there is no state law setting a higher minimum age.
  • Most major rental companies charge a daily young driver fee of $15 to $30 if you are under 25, which can add $100 to $200 to a week-long rental.
  • A few rental companies waive or reduce the young driver fee at age 21, so comparing companies before booking can save money.
  • You will need a credit card in your own name to complete the rental, even if someone else is paying for it.

What documents you need to rent at 18 or 19

To rent a car in Arizona at 18 or 19, bring your valid Arizona driver's license or out-of-state license. The license must not be expired, and your name on the license must match your credit card exactly. If your name has changed since your license was issued, bring a document that shows the change—a marriage certificate, divorce decree, or court order—because the rental agent will compare all three documents.

You will also need a credit card in your own name. The rental company will place a hold on the card (usually $200 to $500) to cover potential damage or fuel charges. If you don't have a credit card, some companies accept debit cards, but they may require additional documentation or a larger hold. Call the specific rental location before you arrive to confirm their debit card policy, because it varies by company and sometimes by individual location.

If you're renting with an international license, bring your passport as well. Arizona accepts valid foreign licenses, but rental companies often want to see a passport to verify your identity.

Young driver fees and how they add up

The young driver fee is a daily charge that applies to anyone under 25 at most major companies. On a five-day rental, a $20 daily fee becomes $100 in extra charges on top of the base rental rate. On a two-week rental, the same fee totals $280. These fees are not optional—they're automatically added to your bill if you fall into the age bracket.

Some companies structure the fee differently. Enterprise, for example, charges the fee for drivers under 25 at most Arizona locations. Hertz charges it for drivers under 25 as well. Budget and Avis have similar policies. National and Alamo sometimes waive it for members of their loyalty programs, so if you rent frequently, joining their free program before booking can save you money.

A few smaller or regional companies—and occasionally a specific location of a major company—may waive the fee at 21 instead of 25. This is not common, but it's worth checking the rental company's website or calling ahead if you're 21 to 24 and want to compare options.

Insurance and liability when you're under 25

Rental companies offer collision damage waiver (CDW) and liability insurance as add-ons. If you're under 25, you should understand that the young driver fee does not include insurance—it's straightforward a risk surcharge. You still have to decide whether to buy the rental company's insurance or rely on your own car insurance or credit card coverage.

Check your personal car insurance policy before you rent. Many policies cover rental cars, but some exclude drivers under 25 or have lower limits for rental vehicles. Call your insurance company and ask specifically whether your policy covers a rental car in Arizona and whether there are any age restrictions. If you have no personal coverage, the rental company's CDW typically costs $15 to $25 per day and covers damage to the rental vehicle.

Your credit card may also offer rental car coverage. Premium credit cards sometimes include this benefit, but it usually applies only to the primary cardholder and may not cover drivers under 25. Check your card's benefits guide or call the card issuer before you rent.

Restrictions on where you can drive and what you can rent

Arizona has no state law that restricts where drivers under 25 can drive or what size vehicle they can rent. However, some rental companies impose their own rules. A few companies require drivers under 21 to sign an agreement stating they won't drive outside Arizona or into Mexico. Some also restrict access to premium or luxury vehicles for drivers under 25, meaning you may not be able to rent a sports car or high-end sedan even if you're willing to pay for it.

These restrictions vary by company and location. When you book online or call, ask whether there are any vehicle restrictions for your age. If you have your heart set on a specific type of car, confirm it's available to you before you complete the reservation.

How to minimize costs if you're under 25

Compare rental companies before you book. The young driver fee varies, and some companies may be cheaper overall even with the fee included. Use a rental comparison website, but also call the specific location where you'll pick up the car, because fees can differ between locations of the same company.

If you're 21 or older, ask whether the company offers any discounts for young drivers or whether joining a loyalty program waives the fee. Some companies reduce the fee for members. If you're renting for a week or longer, the savings from a loyalty program membership can offset the fee entirely.

Consider whether you need a rental car at all. If you're in Phoenix, Tucson, or another city with rideshare services, using a ride service for a few trips may cost less than renting for a short period. If you do rent, book for the shortest time you actually need rather than rounding up to a full day.

What happens if you're under 18

You cannot rent a car in Arizona if you're under 18, regardless of whether you have a valid driver's license. This is a company policy across all major rental agencies, not a state law, but it is universal. If you're 17 and need a car, you'll have to ask someone 18 or older to rent it in their name. That person becomes the renter of record and is responsible for any damage or violations, so make sure it's someone you trust.

If someone else rents the car for you, you can still drive it as long as you have a valid license and are listed as an authorized driver on the rental agreement. The person who rents it will pay the rental fee and any young driver fee if they're under 25, and they'll be liable for damage.

Frequently Asked Questions

Can I rent a car in Arizona at 18 without a credit card?

Most companies require a credit card in your name to place a hold for potential damage. Some accept debit cards, but they may require a larger hold ($500 or more) and additional ID. Call the rental location before you arrive to confirm their debit card policy, because it varies.

Do I have to pay the young driver fee if I'm 24?

Yes, at most major rental companies. The fee applies to anyone under 25. A few smaller companies or specific locations may waive it at 21, so it's worth calling ahead to compare, but you should expect to pay it at Enterprise, Hertz, Budget, Avis, and National.

Will my parents' car insurance cover me if I rent a car?

Possibly, but you need to check with their insurance company directly. Some policies cover rental cars for household members, but others exclude drivers under 25 or have lower limits. Ask before you rent so you know whether you need to buy the rental company's insurance.

Can I rent a car in Arizona if my license is from another state?

Yes. Arizona accepts valid driver's licenses from all U.S. states and territories. Your out-of-state license must not be expired, and your name must match your credit card. If you have an international license, bring your passport as well.

What if I get into an accident and I'm under 25?

The young driver fee does not affect your liability for an accident. If you caused damage, you're responsible for it whether or not you paid the young driver surcharge. This is why checking your insurance coverage before you rent is important—the young driver fee is a risk charge, not insurance.
