Turning 18 makes you a legal adult, but not a rental customer in most of the country. Whether you can rent a car at 18 depends almost entirely on the state, because two states force rental companies to say yes while the rest let them say no. Here are the two exceptions, the real fees, and the workarounds.
Quick Answer
Usually no — but yes in two states. Only New York and Michigan require rental car companies to rent to drivers as young as 18. Everywhere else, the practical minimum at major brands is 20 or 21, and renters under 25 almost always pay a daily young-driver surcharge on top of the base rate.
- Only in New York and Michigan do 18-to-20-year-olds have a general legal right to rent from major companies.
- Elsewhere, Hertz generally rents at 20 (19 in Alabama and Nebraska); Enterprise, Avis, and Budget generally start at 21.
- Expect a steep daily underage fee: Avis lists $84 per day for 18-to-20-year-olds in New York and $41 in Michigan.
- US government and military travelers on official orders can typically rent at 18 nationwide, often with the surcharge waived.
- Zipcar (university accounts) and Turo (lower-value cars) offer limited 18+ options with their own fees and restrictions.

Why Only New York and Michigan Allow Renting at 18
There is no federal minimum age for renting a car. Companies set their own floors because crash risk and claim costs peak with the youngest drivers. Two states override that with civil-rights-style rules.
New York General Business Law § 391-g makes it unlawful to refuse to rent to a licensed driver 18 or older solely because of age, and the state’s highest court confirmed in 1997 that a lack of available insurance is no excuse. The statute lets companies pass the extra insurance cost of young drivers on to them, so New York’s surcharges are among the largest anywhere — the state protects your right to rent, not to rent cheaply. Michigan got there through the courts: a 2000 case against Hertz (Bickham v. Hertz Rent-A-Car) applied the state’s Elliott-Larsen Civil Rights Act, which bars age discrimination in public services, to car rental. Major brands in Michigan have rented to licensed 18-year-olds, with a surcharge, ever since.
One near-miss worth knowing: a 2019 Maryland rule requires rentals at 18, but only for replacement vehicles during warranty or recall repairs — no general right to rent. Everywhere outside New York and Michigan, companies set the bar where they like, usually 21. Hertz publishes 20 at most US locations and 19 in Alabama and Nebraska, but 18-year-olds are still turned away at nearly every counter outside the two mandate states.
Which Companies Rent at 18 and What It Costs
All the major national brands comply with the New York and Michigan rules, so the real difference between them is price. The young-driver fee applies to every rental day, stacks on top of the base rate and taxes, and is higher for 18-to-20-year-olds than for 21-to-24-year-olds. An 18-year-old in New York can pay more per day in surcharges than the base rate of the car itself.
| Company | Minimum age (most states) | Minimum in NY / MI | Published under-21 daily surcharge (NY / MI) |
|---|---|---|---|
| Avis | 21 | 18 | $84 in NY / $41 in MI (ages 18-20) |
| Budget | 21 | 18 | Similar structure to sister brand Avis; confirm at booking |
| Enterprise | 21 | 18 | $64.75 in NY / $36.50 in MI (ages 18-20), per its under-25 FAQ |
| Hertz | 20 (19 in AL and NE) | 18 | Varies by location; disclosed at booking |
These figures come from the companies’ own age-policy pages as of our last check; they change without notice and vary by location, so treat them as ballpark, not a quote. Two patterns hold across brands: young renters are limited to mainstream vehicle classes (economy through standard SUVs) until 25, and standard requirements still apply — a valid license, often held for at least a year, plus a credit or debit card in your own name, with debit cards triggering extra ID and deposit checks.
Realistic Alternatives If You Are 18 to 20
If you are outside New York or Michigan, or the surcharge math kills your budget, a few legitimate paths remain.
Government and military orders. Most major brands rent to US government and military personnel as young as 18 on official orders, typically with the underage fee waived. Bring your orders and government ID.
Membership waivers. Some memberships and corporate codes lower the age floor or waive the fee — USAA-affiliated rates are the best-known example. AAA membership waives Hertz’s Young Renter Fee, but only for members ages 20 to 24 booking with the AAA discount code, so it does not help 18- and 19-year-olds. Verify any waiver is still active before you book.
Car sharing at 18. Zipcar accepts university-account members at 18, though under-21 drivers are generally limited to vehicles based at their campus; standard membership is 21+ except for residents of New York, Michigan, and Maryland. Turo’s US floor is 18, but under-21 drivers are limited to lower-value vehicles, and daily young-driver fees plus host-set minimums put many listings out of reach until 21 or 25.
Ride the surcharge only when it wins. For a one-day airport run in Michigan, a $36-$41 surcharge on a cheap economy car can still beat two long ride-share trips. For a week, the published under-21 surcharge alone runs from about $255 in Michigan to nearly $590 in New York — a bus, train, or over-25 driver in your group is usually smarter.
Common Mistakes To Avoid
- Booking a prepaid rate at 18 outside New York or Michigan — you will be refused at the counter, and refunds on prepayments are a hassle.
- Comparing base rates only. The per-day young-driver fee is often hidden until checkout, so compare surcharge-included totals.
- Assuming a parent can rent the car and hand you the keys. An unlisted 18-year-old driver typically voids the damage waiver and leaves you personally liable.
- Skipping the insurance question. Credit-card coverage is usually secondary and you may have no auto policy of your own — know what covers the car and your liability before declining anything.
- Showing up with a license held less than a year. Many locations require 12 months of licensed driving, even in New York and Michigan.
- Ignoring vehicle-class limits. A premium SUV or performance-car reservation at 18 gets rewritten or refused at pickup.
Frequently Asked Questions
Can you rent a car at 18 in any state?
Only in New York and Michigan from the major brands, which must rent to licensed drivers 18 and older there — with hefty daily surcharges. Everywhere else, companies set their own minimums, usually 21 (Hertz is 20 at most locations), and will decline an 18-year-old renter.
How much extra does an 18-year-old pay to rent a car?
Plan on roughly $36 to $84 per rental day on top of the base rate, depending on brand and state. Avis has published $84 per day for ages 18-20 in New York and $41 in Michigan; Enterprise’s listed figures are somewhat lower. Fees change often, so check the surcharge-included total before booking.
Why do New York and Michigan allow renting at 18?
Because state civil-rights rules treat a blanket refusal as age discrimination. New York’s General Business Law § 391-g bars refusing licensed adult drivers based on age alone, and a 2000 Michigan case against Hertz applied the Elliott-Larsen Civil Rights Act to car rental. Both states still let companies price young renters higher.
Can an 18-year-old rent a car with a debit card?
Often yes, with extra friction: a larger deposit hold, proof of a return travel ticket at airports, or extra ID checks, and some neighborhood locations still require a credit card. The card must be in the renter’s own name — a parent’s card will not work.
Does being in the military help you rent at 18?
Yes. Most major companies rent to US government and military personnel at 18 on official orders, generally with the surcharge waived. Off-duty leisure rentals usually fall back to standard rules, though USAA-affiliated benefits can lower age floors and fees — verify current terms before booking.
Is Turo or Zipcar a better option at 18?
Sometimes, for short local trips. Zipcar takes 18-year-olds through university accounts, with under-21 members mostly limited to on-campus vehicles and modest fees. Turo’s US floor is 18 for lower-value cars, but daily young-driver fees and host minimums shrink the selection. For multi-day trips, compare totals against a traditional rental.
