What you need to rent a car in the United States

To rent a car in the USA, you need a valid driver's license, a credit card in your name, and proof of insurance. Most rental companies require you to be at least 25 years old, though some allow renters as young as 18 or 21 with an additional young driver fee. The rental agent will check your license, run it against their system, and hold an amount on your credit card as a deposit — this is not a charge, but a hold that releases when you return the car.

You'll also need to decide on insurance coverage before you drive off the lot. Your personal auto insurance may already cover rental cars, or your credit card may offer rental protection. If neither applies to you, the rental company will offer their own coverage, which you can purchase by the day. Bring your insurance card or credit card benefits documentation so the agent can verify what's already covered.

Some companies ask for a second form of ID and proof of your current address. If you're renting under a corporate account or with a frequent renter program, you may skip some of these steps, but the basics — valid license, credit card, and insurance information — are always required.

Key Takeaways

  • You must have a valid driver's license, a credit card in your name, and proof of insurance coverage before renting a car.
  • Most major rental companies require you to be at least 25 years old; younger renters pay an additional daily fee and may face restrictions on vehicle types.
  • The rental company will place a hold on your credit card for the full estimated cost plus a damage deposit, which releases after you return the car undamaged.
  • Your personal auto insurance or credit card benefits may already cover rental cars, so check before paying the rental company's daily insurance rate.
  • Rental rates, mileage policies, and fuel options vary widely between companies and locations, so comparing quotes before booking saves money.

How rental rates and mileage policies work

Rental companies price by the day, and rates change based on location, season, vehicle type, and how far in advance you book. A compact car in a small town costs far less than the same car at an airport in a major city during peak travel season. Booking a week or more in advance usually costs less per day than a same-day rental, and weekend rates often differ from weekday rates.

Mileage policies fall into two categories: unlimited mileage or a daily mileage allowance with overage charges. Most national chains offer unlimited mileage on standard rentals, but some regional companies and budget brands charge per mile after you exceed your daily limit — typically 100 to 150 miles per day. If you plan to drive long distances, confirm the mileage policy before you book, because overage charges add up quickly.

The quoted rate usually includes the base rental fee only. Taxes, airport fees (if you rent at an airport), and insurance are added at checkout. Some companies charge a facility fee or vehicle licensing recovery fee. Always read the full price breakdown before you confirm your reservation.

Fuel options and what happens if you return the car empty

When you pick up the car, the agent will show you the fuel level and ask how you want to handle fuel. You have three main options: return the car with a full tank (you pay for a full tank upfront and keep any unused fuel), return it at the same level you picked it up (you pay for whatever fuel you used), or let the company refuel it and charge you their rate (usually higher than gas station prices).

If you choose the prepaid full-tank option and return the car with half a tank, you lose the cost of that fuel — the company does not refund unused gas. If you return the car empty or nearly empty under a pay-as-you-go plan, the company charges you their fuel rate, which is typically 50 to 100 percent higher than what you'd pay at a pump. The cheapest option is usually to fill the tank yourself at a gas station near the rental location before you return the car, then return it full.

Some companies offer a "fuel exchange" where you buy a full tank at pickup and return the car empty with no overage charge. This works if you know you'll use most of a tank; it does not work if your trip uses less fuel than that.

Damage, tolls, and what you're responsible for

You are responsible for any damage to the rental car beyond normal wear and tear. The rental company photographs the car before and after your rental and compares the images. Minor scratches, dents, and chips that existed before your rental should be documented on your contract — review the damage report carefully before you leave the lot and ask the agent to note anything you see.

If you cause damage during your rental, the company will charge you for repairs. If you have collision coverage through your personal insurance or credit card, that coverage may pay for the damage, and you'll only owe your deductible. If you purchased the rental company's damage waiver, you typically owe nothing. If you have no coverage and no waiver, you pay the full repair bill.

Tolls are your responsibility. If you drive through a toll road or toll bridge, you must pay the toll. Some rental companies offer a toll pass or will bill you later for tolls they discover through license plate readers. Ask about toll policies when you pick up the car, especially if you're renting in a state or region with many toll roads.

Age restrictions and additional fees for young renters

Most national rental companies (Enterprise, Hertz, Budget, Avis, National) allow renters as young as 21, but charge an additional daily fee — typically $15 to $30 per day — for drivers under 25. Some companies restrict drivers under 25 to certain vehicle types, such as no luxury or high-performance cars. A few regional or budget companies require renters to be 25 or older with no exceptions.

If you're under 21, your options are limited. Some companies allow 18-year-olds to rent with a parent or guardian present and co-signing the contract, but this is rare. Most require you to be at least 21. Check the specific company's policy before you book, because restrictions vary.

The young driver fee is separate from the daily rental rate and is not waived by frequent renter programs or corporate discounts. If you're renting for a week as a 23-year-old, expect to pay the standard daily rate plus $15 to $30 per day for the age surcharge.

One-way rentals and drop-off fees

A one-way rental means you pick up the car in one city and return it in another. This costs more than a round-trip rental from the same location because the company must move the car back or position it for another customer. Drop-off fees vary widely — sometimes $50, sometimes $500 or more, depending on the distance between pickup and return locations and whether the return location is a high-demand area.

If you're renting in a major city and returning in a smaller town far away, expect a substantial drop-off fee. If you're returning to another major city on the same rental company's network, the fee may be lower or waived. Always get a quote for the specific one-way route before you book, because the fee is not always obvious in the initial search results.

Some companies offer better one-way rates if you book far in advance or if you're a member of their loyalty program. Comparing quotes across multiple companies for your specific route can save hundreds of dollars.

Insurance coverage: what your personal policy and credit card cover

Before you pay for the rental company's insurance, check whether you're already covered. Most personal auto insurance policies extend to rental cars, but some exclude them or limit coverage to the USA only. Call your insurance company or check your policy documents to confirm what's covered and what your deductible is.

Many credit cards offer rental car coverage as a cardholder benefit. This typically covers collision and theft but not liability (damage you cause to other people or property). The coverage usually applies only if you charge the entire rental to that card. Check your card's benefits guide or call the card issuer to learn what's covered, what the deductible is, and whether the coverage applies in all countries or the USA only.

If your personal insurance or credit card covers the rental, you can decline the rental company's damage waiver and save $15 to $30 per day. If you have no coverage, purchasing the rental company's collision damage waiver or loss damage waiver protects you from paying out of pocket for repairs. Read the waiver terms carefully — some exclude certain types of damage, such as damage from off-road driving or from driving under the influence.

Reservation changes, cancellations, and what to do if you need to modify your booking

Most rental companies allow free cancellations and changes up to a certain time before your pickup — usually 24 to 48 hours. If you cancel or change your reservation within that window, you owe nothing. If you cancel closer to your pickup date, you may lose your deposit or be charged a cancellation fee. Check your confirmation email for the cancellation policy specific to your reservation.

If you need to extend your rental after you've picked up the car, call the rental location or use the company's app or website to request an extension. Extending by a day or two is usually straightforward and costs the daily rate for those extra days. If the car is already reserved for another customer, you may not be able to extend and will need to return it on time.

If you need to shorten your rental, returning the car early typically does not refund the unused days. Some companies offer a courtesy reduction if you return within a day of your original return date, but this is not may provide. Read your confirmation to see what changes are possible without penalty.

Frequently Asked Questions

Do I need a credit card to rent a car?

Yes, rental companies require a credit card in your name to hold as a deposit. Debit cards are not accepted because the company cannot place a hold on them the same way. The card must be in the renter's name — you cannot use someone else's card.

Can I rent a car with an international driver's license?

An international driver's license alone is usually not enough. Most rental companies require a valid driver's license from your home country plus an international driving permit (IDP). Some companies accept only a US state license or a license from your country of residence. Call the rental company before you book to confirm what documents they accept.

What happens if I get a speeding ticket or parking ticket while renting?

You are responsible for paying any traffic or parking tickets you receive while driving the rental car. The rental company will not pay the ticket. If the ticket is issued to the rental car's license plate, the rental company may receive notice and bill you for the ticket plus an administrative fee. Pay any tickets promptly to avoid additional charges.

Can I rent a car if I have a suspended or revoked license?

No. Rental companies run your license through their system and will not rent to you if your license is suspended, revoked, or expired. You must have a valid, active driver's license to rent a car in the USA.

What's the difference between a damage waiver and liability coverage?

A damage waiver covers repairs to the rental car if you cause an accident or damage it. Liability coverage covers damage you cause to other people's property or injuries to other people. Rental companies offer both separately. Your personal insurance typically covers both, so check your policy before paying for the rental company's coverage.
