How Old Do You Have to Be to Rent a Car?

Renting a car sounds straightforward until you're standing at the counter and find out your age is working against you. Minimum age requirements for car rentals aren't set by federal law — they're set by individual rental companies, sometimes layered on top of state laws. That means what applies to you depends on where you're renting, which company you're using, and what you're trying to rent.

The Standard Minimum Age Is 25 — But It's Not the Only Age That Works

Most major rental car companies in the United States use 25 as the age at which a renter is considered a standard, full-rate customer. Below that threshold, you're generally still able to rent — but with conditions attached.

Renters between 21 and 24 can typically rent from most major companies, but they're charged what's called a young driver surcharge (sometimes called an "underage fee"). This is a daily add-on fee that can range from roughly $25 to $35 per day, though the exact amount varies by company, location, and vehicle class. On a week-long trip, that adds up quickly.

Renters between 18 and 20 face a more restricted picture. Some companies won't rent to this age group at all. Others do — often at airport locations less than non-airport ones — but the surcharges are higher and vehicle selection is more limited.

Why Rental Companies Set Age Minimums

This comes down to statistical risk. Younger drivers, particularly those under 25, have higher rates of accidents and claims according to insurance actuarial data. Rental companies carry risk on every vehicle they put on the road, so they price that risk into their policies. Age thresholds and surcharges exist to offset that exposure — not to comply with a specific law, but to manage their own liability.

How State Laws Factor In 🗺️

A handful of states have laws that limit how rental companies can apply age-based restrictions. Michigan, New York, and a few others have regulations that either prohibit young driver surcharges entirely or cap how they can be applied. This means a renter under 25 might not pay any additional fee in those states — or might pay a reduced one.

This is one of the most important variables in this topic: what's true at a rental counter in Texas may not be true at a counter in New York. If you're renting in a state with consumer protections around age surcharges, those protections apply regardless of what the company's national policy says.

Variables That Shape Your Specific Outcome

Vehicle Type Matters More Than People Expect

Renting a standard economy sedan at 22 is very different from trying to rent a luxury SUV or a specialty vehicle like a van or convertible. Premium and specialty vehicle classes frequently carry higher minimum age requirements — sometimes 25, sometimes higher. Even renters who are technically old enough to rent in general may find they're blocked from specific vehicle categories.

Credit Cards and Other Ways Around the Surcharge ✅

Some premium travel credit cards include young driver fee waivers as a cardholder benefit when the rental is booked and paid through that card. This is worth checking before booking, because it can eliminate a fee that would otherwise add $150 or more to a week-long rental. The card's terms define whether this applies and which rental companies honor it.

Corporate and government rates sometimes carry age exemptions as well. If you're renting for work through a company account, the corporate agreement may waive surcharges for younger employees.

International Rentals Work Differently

Outside the U.S., minimum age rules vary significantly by country. Some European countries set their own legal minimums — often 21 — and local rental companies may require additional fees for drivers under 25 or under 23. In some markets, the minimum age to rent any vehicle is 18 without a surcharge. In others, it's strictly 25 with no exceptions. If you're renting abroad, the rental company's local policies in that country apply, not what you're used to in the U.S.

What "Additional Driver" Rules Mean for Age

If you're adding a second driver to a rental — a common setup for long road trips — that driver's age is evaluated separately. A younger co-driver may trigger a surcharge even if the primary renter is over 25. Most companies apply the young driver surcharge to any driver listed on the contract who falls below their threshold.

Where This Leaves You

The answer to how old you need to be depends on the company, the state, the vehicle class, the pickup location, and whether you have any exemptions through your credit card, employer, or military service. The baseline rule — 25 for no surcharge, 21–24 with fees, under 21 highly restricted — is a reasonable starting point, but the specifics of your rental situation may change that picture considerably.
