"In most US states, 18-year-olds can't rent a car. Two states — New York and Michigan — require all major brands to rent at 18. Fox corporate locations go down to 19 anywhere in the country. Every other path requires being 20 or 21."
You're picking up in New York or Michigan, renting from a Fox corporate location at 19, or traveling on active-duty military orders
Booking with a supplier that has a 21 minimum and assuming you'll be able to rent — you won't, and the booking won't be honored at the counter
In most US states, no major supplier rents to an 18-year-old — the floor is 20 or 21 depending on the brand. Two states override that: New York and Michigan both have laws requiring rental companies to serve licensed drivers from age 18. Fox, alone among major brands, sets its corporate-location minimum at 19 regardless of state. Every other path requires being 20 or 21.
A search result that says "you can rent at 18" is almost always describing New York or Michigan — not a nationwide policy. What follows is which states change the rules, which supplier is the exception, and what the access actually costs once you're through the door.
New York and Michigan: the 18 exception
Both states have consumer protection laws that prohibit rental companies from refusing to serve a fully licensed driver solely on the basis of being under 21. Every major brand operating in those states — Enterprise, Avis, Alamo, National, Budget, Hertz, Dollar, Thrifty, Sixt — must accept renters aged 18 and older. You walk in, you show a valid license and a credit card, and the booking is honored. The state law is clear on this.
The access is real. The cost is steep. Suppliers respond to the mandated access with a separate, higher surcharge for the 18–20 age bracket — on top of the base rate, not included in it. These are not the $20–$37/day rates that apply to 21–24 year-olds. In New York, the 18–20 surcharge runs $37–$84/day depending on supplier. Michigan surcharges are lower but still significantly above the 21–24 rates.
| Supplier | 18–20 surcharge | Risk | What happens |
|---|---|---|---|
| Avis | $84/day (NY) / varies (MI) | High | Among the highest published 18–20 surcharges in New York. Michigan rate lower but not published as a flat figure. Applies on top of base rate. |
| Enterprise | $64.75/day (NY) / $36.50/day (MI) | High | Specific published figures for both states. New York surcharge for 18–20 is $64.75/day; Michigan is $36.50/day. Both apply in addition to the base rental rate. |
| Alamo | ~$65/day (NY) / ~$42/day (MI) | High | Published figures for 18–20 year-olds vary by location. New York typically runs ~$65/day; Michigan ~$42/day. Higher than the standard 21–24 youthful surcharge at the same supplier. |
| Hertz | Not published flat (NY/MI) | Medium | Hertz does not publish a flat 18–20 surcharge figure. Their standard minimum is 20 nationwide, so this bracket applies only in NY/MI. Start a reservation with your date of birth to see the exact amount before confirming. |
| Sixt | $37-$61/day (NY) | High | New York 18–20 surcharge runs $37–$61/day. Sixt does not confirm 18-access in Michigan. The young driver fee applies even on government rentals at Sixt, unlike most other suppliers. |
Daily surcharges for drivers aged 18–20 in New York and Michigan, per published supplier rental conditions, accessed July 2026. Applies on top of the base rental rate.
On a five-day rental in New York at $64.75/day, the Enterprise surcharge alone adds $323.75. That figure is on top of whatever the car costs. It's not a reason to avoid renting — sometimes it's the right call regardless of cost — but anyone budgeting only the advertised base rate will be caught off-guard at the counter.
Fox: the one supplier with a nationwide 19 minimum
Fox Rent A Car is the only major US supplier with a minimum age below 20 that applies outside of New York and Michigan. At Fox corporate locations, drivers aged 19 and older can rent with a valid US license. Active-duty military on official travel orders can rent at 18 at any Fox corporate location.
There are two things worth understanding before banking on this. First, the 19-minimum applies only at Fox corporate locations — Fox affiliate locations are excluded from the program, and affiliates make up a meaningful share of Fox's network. When searching for Fox locations, confirm the specific pickup point is a corporate location before booking. Second, Fox publishes two separate surcharges for young renters: $22/day for drivers aged 19–24, and a higher $25.99/day for drivers specifically under 21. If you're 19 or 20, the under-21 rate applies, not the standard young driver rate.

Every supplier's minimum age at a glance
Green means a genuine path exists outside NY/MI. Amber means conditional access. Red means the only route is New York or Michigan state law — or you're out of options.
| Supplier | Minimum age | Risk | What happens |
|---|---|---|---|
| Fox | 19 (most US locations) | Medium | Closest to 18-accessible without a state law. Fox corporate locations rent from 19 to drivers with a valid US license. Active-duty military on official orders qualify at 18. Not available at Fox affiliate locations. |
| Hertz | 20 (most US) / 18 (NY, MI) | Medium | State-gated at 18. Hertz rents from 18 in New York and Michigan only, as required by state law. Standard US minimum is 20 everywhere else. Alabama and Nebraska: minimum age 19. |
| Dollar | 20 (most US) / 18 (NY, MI) | Medium | State-gated at 18. Rents from 18 in New York and Michigan only. Standard minimum is 20 at most US locations. Sister brand to Thrifty under the Hertz Corporation. |
| Thrifty | 20 (most US) / 18 (NY, MI) | Medium | State-gated at 18. Same policy structure as Dollar. Minimum age 20 at most US locations; 18 in New York and Michigan per state law. Government employees on orders qualify at 18 anywhere. |
| Enterprise | 21 (most US) / 18 (NY, MI) | High | State-gated at 18 only. Minimum 21 everywhere else. US government employees on official orders can rent at 18 at any location. No other path to 18-year-old access outside NY/MI. |
| Alamo | 21 (most US) / 18 (NY, MI) | High | State-gated at 18 only. Standard minimum is 21 throughout the US and Canada. Michigan and New York exception mandated by state law. Military and government on orders also exempt at 18. |
| National | 21 (most US) / 18 (NY, MI) | High | State-gated at 18 only. Same policy as Alamo (same parent company). Standard minimum is 21. Military and government employees on official orders can rent at 18 at any location. |
| Avis | 21 (most US) / 18 (NY, MI) | High | State-gated at 18 only. Minimum 21 at most US locations. New York minimum is 18 with an $84/day surcharge for ages 18–20. Michigan minimum is 18. USAA waives the young driver fee but does not change the minimum age. |
| Budget | 21 (most US) / 18 (NY, MI) | High | State-gated at 18 only. Standard minimum is 21. New York and Michigan exceptions required by state law. Credit card required for all renters under 25 — no debit card accepted for young renters. |
| Sixt | 21 (most US) / 18 (NY only) | High | State-gated at 18 in New York only. Standard minimum is 21 throughout the US. Government renters qualify at 18 at any location with valid government ID. Michigan exception applies to most suppliers but not confirmed for Sixt specifically. |
| Nu | 21 (all US locations) | High | No path to renting at 18 or under 21. Nu sets a hard minimum of 21 with no state-law exceptions published and no government or military override. Minimum age of 21 applies at all Nu locations. |

The pattern is consistent: outside New York and Michigan, the realistic floor for most major brands is 20 (Hertz, Dollar, Thrifty) or 21 (everyone else). Nu has the strictest policy — a hard minimum of 21 with no state-law exception published and no military or government override. An 18-year-old who shows up at a Nu counter will be turned away regardless of what any third-party booking site showed at checkout.
What renting at 18 or 19 actually costs
The surcharge for an 18–20 year-old is always higher than the standard young driver fee that applies to 21–24 year-olds at the same supplier. At Fox, the under-21 rate is $25.99/day versus $22/day for the 21–24 bracket. In New York, the gap is much wider. Seven days at Enterprise in New York costs $237.40 more in age surcharge alone for an 18-year-old versus a 21-year-old renting the same car. That's before the base rate.
The math is worth sitting with before booking. Sometimes renting is still the right call at any cost. But it's also worth asking whether the trip can be structured differently — waiting until a 20th birthday, routing through a Fox corporate location, or splitting transportation for part of the journey.
Membership waivers (AAA at Hertz, USAA at five brands) reduce or eliminate the young driver fee for 21–24 year-olds but don't lower the minimum age floor. They don't help at 18 or 19.
Card and vehicle restrictions
Clearing the age minimum is only half the equation. Two additional restrictions apply at most suppliers for renters under 21, and sometimes under 25.
Credit card requirement
Most suppliers require a credit card in the renter's name for young renters. Budget makes this explicit: no debit cards accepted for any renter under 25. Enterprise and Alamo describe debit card acceptance as location-specific — some branches accept debit with additional requirements like a higher deposit hold, some don't. If you're 18 and planning to use a debit card, confirm the payment policy at your specific pickup location before you show up. A declined debit card at the counter is a denied rental.
Vehicle class restrictions
Luxury vehicles, premium SUVs, sports cars, and specialty vehicles are off-limits for renters under 25 at virtually every supplier — and for renters under 21, the restrictions extend to additional categories. At Sixt, the under-25 restriction excludes premium, luxury, sports, and specialty categories outright. At Enterprise, renters 21–24 are limited to economy through full-size cars, minivans, cargo vans, pickup trucks, and compact to standard SUVs — renters under 21 face tighter limits still. The practical effect is that an 18 or 19-year-old is limited to economy through intermediate vehicles at most locations.
If you're renting internationally, the minimum age structure is different again. Most major European destinations set the floor at 21 — Ireland, Spain, France, Greece, and Portugal all enforce this regardless of the supplier. Germany and Croatia are the two notable exceptions where some suppliers honor an 18-year-old's license, though Germany adds a mandatory CDW purchase for drivers aged 18–22 that credit cards don't satisfy. Our destination guides cover the specifics for Ireland, Iceland, Hawaii, and Costa Rica.
The verdict
If you're 18 and haven't booked yet: Your realistic options are a New York or Michigan pickup with any major brand, or — if you turn 19 before the trip — a Fox corporate location anywhere in the country. Outside those paths, no major supplier will honor the booking at the counter. If you're picking up in New York or Michigan, factor in the 18–20 surcharge before choosing a brand — it runs $37–$84/day on top of the base rate. The cheapest total in NY/MI is rarely whoever has the lowest advertised base rate; compare the all-in daily figure, not the headline price.
If you're already booked: Confirm three things before pickup. One: your location is in New York or Michigan, or is a Fox corporate location. Two: the young driver surcharge for your age bracket (18–20, not 21–24) is showing in your booking total — if it isn't, the counter will add it. Three: you have a credit card in your name, not just a debit card. Budget won't accept debit from renters under 25; other suppliers may also decline it.
If the rental was denied at the counter: A denial on age grounds when the booking site didn't disclose the minimum age is a legitimate dispute. Contact the booking platform first if you booked through a third party — they're responsible for accurate age disclosures. If you booked direct and the supplier's own site didn't surface the restriction, raise it in writing with your booking confirmation. Your credit card issuer is the next step if the charge isn't reversed within a week.

Frequently asked questions
Can you rent a car at 18?
In most US states, no — the standard minimum age at most major brands is 20 or 21. The two exceptions are New York and Michigan, where state law requires rental companies to rent to drivers aged 18 and older. Fox is the closest exception to a nationwide rule: their corporate locations rent from age 19, and active-duty military on orders can rent from 18.
Which states allow car rentals at 18?
New York and Michigan both have state laws that require car rental companies to rent to licensed drivers aged 18 and older. In Alabama and Nebraska, the minimum age is 19. In Mississippi, the minimum is 21 regardless of the renter's age. In all other states, rental companies set their own minimums — typically 20 or 21 depending on the brand.
Which rental company has the lowest minimum age?
Fox Rent A Car has the lowest minimum age of any major US brand at most locations: 19 years old at corporate locations nationwide. Most other suppliers require 20 (Hertz, Dollar, Thrifty) or 21 (Enterprise, Avis, Budget, Alamo, National, Sixt) outside of New York and Michigan. Nu Car Rental has a hard minimum of 21 with no exceptions.
How much does it cost to rent a car at 18 in New York?
The daily surcharge for 18–20 year-olds in New York runs from around $37–$61/day at Sixt up to $84/day at Avis, on top of the base rental rate. Enterprise publishes $64.75/day for 18–20 year-olds in New York. These are materially higher than the $20–$37/day young driver fees that apply to 21–24 year-olds at the same suppliers.
Can an 18-year-old rent a car without a credit card?
Most suppliers require a credit card for renters under 25, though policies vary. Budget explicitly requires a credit card for all renters under 25 — no debit cards accepted. Enterprise and Alamo list debit card policies as location-specific. If you're 18 and planning to pay with a debit card, confirm the policy at your specific location before arriving at the counter.
I'm 18 and already booked — what should I check before pickup?
Confirm your pickup location is in New York or Michigan, or that you're renting from a Fox corporate location (not affiliate). Verify the daily surcharge for your age bracket is shown in your booking total — it should be disclosed at reservation, not revealed at the counter. Bring a valid credit card in your name; many locations won't accept debit for renters under 21. Review the vehicle class restrictions for your age bracket before assuming you can change to a different car category.
Can active-duty military rent a car at 18?
Yes, at most major brands. US government employees and active-duty military on official orders can typically rent at 18 at any US location, with official orders required at the counter. The notable exception is Sixt, which still applies the young driver surcharge even on government rentals — the only major brand that does. The young driver fee applies at most suppliers even for military members on personal travel.
