Most rental companies will rent to you at 21, but you'll pay an extra daily fee and face stricter rules

You can rent a car at 21 from most major companies — Enterprise, Hertz, Budget, Avis, and National all rent to drivers 21 and older. However, being under 25 triggers an underage driver fee, usually $15 to $30 per day added to your total cost. You'll also face restrictions that don't explore to older renters: some companies won't rent you certain vehicle types (often SUVs or premium cars), some require a credit card in your name, and some have stricter damage policies.

The specific rules vary by company and location. A Hertz location in one state may have different age policies than a Hertz in another. Before you book, check the rental company's website for your exact location, or call the branch directly — the booking site won't always show age-related fees or restrictions until you enter your birthdate during checkout.

Key Takeaways

  • All major rental companies rent to 21-year-olds, but charge an underage driver fee of $15 to $30 per day on top of the base rental rate.
  • You must have a valid driver's license, proof of insurance, and a credit card in your own name; some companies require the card to be a major brand like Visa or Mastercard, not a debit card.
  • Rental companies often restrict what types of vehicles 21-year-olds can rent, commonly excluding SUVs, sports cars, and luxury vehicles.
  • Damage waivers and insurance coverage work differently for underage renters at some companies, so review the damage policy before you complete your reservation.
  • Booking directly through the company's website or calling the branch gives you the most accurate pricing and policy information for your age and location.

What you need to bring to pick up the car

Bring your valid driver's license (a state ID, passport, or international driving permit if you're from outside the US), proof of insurance, and a credit card in your name. The credit card is non-negotiable — rental companies use it to hold a deposit (usually $200 to $500) in case of damage or late return. Some companies accept debit cards, but many do not, so confirm this when you book.

If you're renting in a state other than where your license was issued, bring it anyway — it's still valid. If you're an international visitor, bring your passport and an International Driving Permit (IDP) along with your home country's license. Some rental locations require the IDP; others accept just the home license. Call ahead to confirm.

Proof of insurance can be a printed policy document, a digital copy on your phone, or a letter from your insurance company. If you're on a parent's policy, bring documentation showing your name and coverage details. If you don't have insurance, the rental company will offer you their own coverage — this is expensive but protects you if you cause damage.

How the underage driver fee works and what it covers

The underage driver fee is a daily surcharge added to your rental rate. If you rent a car for three days at $50 per day, plus a $20 underage fee per day, you pay $210 total ($150 for the car, $60 for the age surcharge). This fee does not include insurance, damage waiver, or fuel — those are separate charges.

The fee itself covers nothing except the company's willingness to rent to you. It does not reduce your liability if you damage the car, does not lower your insurance costs, and does not give you better coverage. You still need to decide whether to purchase the rental company's damage waiver or rely on your own insurance.

The fee disappears on your 25th birthday. Some companies begin charging it at 18, others at 21. A few companies have no age-based fee at all but restrict vehicle types instead. Check your specific rental company's policy before you book.

Vehicle restrictions for drivers under 25

Many rental companies won't rent certain vehicles to drivers under 25. The most common restrictions are on SUVs, sports cars, convertibles, and luxury or premium vehicles. Some companies also restrict full-size trucks or vans. Economy and compact cars are almost always available to 21-year-olds.

These restrictions exist because insurance claims data shows higher accident rates for younger drivers in high-value or high-performance vehicles. The restriction is a business decision, not a legal requirement — it varies by company and sometimes by location. A Budget branch in one city might rent SUVs to 21-year-olds while another Budget branch does not.

When you search for a rental online, the system may not show you restricted vehicles at all, or it may show them but block you from booking once you enter your age. Call the branch directly if you want a specific vehicle type — sometimes the agent can override the restriction or point you to a nearby location with different policies.

Insurance and damage coverage at 21

Your own auto insurance may cover rental cars, but you need to confirm this before you rent. Call your insurance company and ask whether your policy covers rental vehicles and what the deductible is. If you're on a parent's policy, ask whether the coverage extends to you as a renter. Some policies cover rentals; others don't.

If your insurance doesn't cover rentals, or if you want to lower your out-of-pocket risk, you can purchase the rental company's damage waiver (also called Loss Damage Waiver or LDW). This typically costs $15 to $25 per day and means you won't pay for damage to the rental car (with some exceptions for gross negligence). At 21, some companies explore stricter terms to your waiver — for example, excluding damage from off-road driving or limiting coverage to minor dents.

Credit cards sometimes offer rental car coverage as a cardholder benefit. Check your card's terms before you rent. If your card covers rentals, you may not need to buy the company's waiver. However, credit card coverage is often secondary (meaning your insurance pays first), and it may have exclusions or a high deductible.

How to find the best rate as a 21-year-old renter

Book directly through the rental company's website or by phone, not through third-party booking sites like Kayak or Priceline. Third-party sites often don't display age-based fees until very late in the booking process, and sometimes they don't show them at all. Booking directly lets you see the full price — base rate plus underage fee — before you commit.

Compare rates across at least three companies (Enterprise, Hertz, Budget, Avis, National, or regional companies in your area). The underage fee varies, and so do base rates. A company with a lower daily rate might have a higher age fee, or vice versa. Calculate the total cost for your rental dates, not just the daily rate.

Ask about discounts when you book. Some companies offer discounts for AAA members, military personnel, students, or corporate affiliations. These discounts sometimes explore to the base rate but not the underage fee, so ask specifically whether the discount stacks with the age surcharge.

What happens if you're 20 or younger

Most major rental companies do not rent to anyone under 21. Enterprise sometimes rents to 18-year-olds with an additional fee and restrictions, but this varies by location. Hertz, Budget, Avis, and National have minimum ages of 21 or 25 at most locations.

If you're under 21, call local rental branches directly — some independent or regional companies may rent to younger drivers. Expect to pay a much higher daily fee and face stricter vehicle restrictions. You'll also need a credit card in your name and proof of insurance.

Some car-sharing services like Turo (peer-to-peer car rental) allow renters as young as 18, though fees and insurance requirements are higher. These are alternatives if traditional rental companies won't rent to you, but read the terms carefully — you're renting from a private owner, not a company, and the rules are different.

Frequently Asked Questions

Can I rent a car at 21 if I don't have a credit card?

Most companies require a credit card in your name for the deposit hold. Some accept debit cards, but many do not. Call the rental branch directly and ask whether they accept debit cards. If they do, bring your debit card and be prepared for the hold to tie up that money for several days after you return the car.

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

Maybe. Call your parents' insurance company and ask whether their policy covers you as a renter. Some policies do; others only cover you if you're driving their car. If you're covered, ask what the deductible is — you may still owe money if you cause damage. If you're not covered, you'll need to buy the rental company's damage waiver or get your own insurance.

What if I get into an accident while renting?

Call the rental company when ready and report the accident. Take photos of the damage, get the other driver's information, and file a police report if anyone was injured or there's significant damage. The rental company will investigate and determine who pays for repairs. If you have insurance or a damage waiver, your coverage will handle it. If you don't, you'll be liable for the full cost.

Do I have to buy the rental company's damage waiver?

No, it's optional. If your own insurance covers rental cars, you probably don't need it. If you don't have insurance, buying the waiver protects you from a large bill if you damage the car. Read the waiver terms carefully — some have exclusions or high deductibles, especially for drivers under 25.

Can I rent a car in one state and return it in another?

Yes, most rental companies offer one-way rentals. You'll pay a drop-off fee (usually $50 to $200 depending on distance), and the rental agreement will specify where you must return the car. Confirm the drop-off location and fee when you book. Some companies charge higher fees for one-way rentals to younger drivers, so ask about this specifically.
