What you need to rent a car in the USA
To rent a car in the United States, 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 21 years old, though some charge extra fees for drivers under 25. A few companies will rent to drivers as young as 18, but expect to pay a daily surcharge of $15 to $30.
Your driver's license must be current and not suspended. If you have an international license, bring both your home country's license and an International Driving Permit (IDP) from your country's automobile association — some rental companies ask for both. A credit card is non-negotiable: rental companies use it to place a hold for the security deposit, which typically ranges from $200 to $500 depending on the car class. Debit cards are rarely accepted for this hold.
Insurance is the third requirement. You can bring proof of your own auto insurance policy, use the rental company's insurance (usually $15 to $25 per day), or purchase coverage through a credit card if your card offers rental car protection. Check your card's terms before you rent — some cards cover collision and theft but not liability, leaving you exposed.
Key Takeaways
- You must present a valid driver's license, a credit card in your name, and proof of insurance coverage before any rental company will hand over keys.
- Drivers under 25 pay daily surcharges that can add $300 to $600 to a week-long rental, so compare total cost across companies before booking.
- The security deposit hold on your credit card can take three to five business days to release after you return the car, even if you paid in full.
- Fuel, tolls, and parking are almost never included in the quoted daily rate, and returning the car on empty can cost $6 to $8 per gallon.
- Damage waivers and liability coverage vary widely by company and state, so read the fine print before you drive off the lot.
Where the daily rate comes from and what it does not include
The advertised daily rental rate covers only the car itself and the basic liability insurance required by law in that state. Everything else costs extra. A $40-per-day economy car can easily become $70 or $80 per day once you add a damage waiver, a second driver, GPS rental, and taxes.
Fuel is your responsibility. You can prepay for a full tank when you rent (usually $50 to $70 for an economy car), or you can return the car with a full tank yourself. If you return it empty or partially full, the rental company will charge you $6 to $8 per gallon to refill it — far more than you would pay at a gas station. Tolls, parking fees, and traffic citations are billed to your credit card weeks or months after you return the car.
Taxes and fees vary by state and city. In some places, rental tax is 10 percent; in others, it is 20 percent or higher. Airport rentals carry an additional airport concession fee, usually 10 to 15 percent on top of the base rate. Renting from an off-airport location (a downtown office or a car dealership) can save 15 to 25 percent on the total bill.
Damage waivers and what happens if you hit something
A damage waiver (also called a loss damage waiver or LDW) is optional insurance that protects you if the car is damaged, stolen, or totaled. Without it, you are liable for the full repair cost or replacement value. With it, you typically pay a deductible of $500 to $1,500 if damage occurs. The waiver itself costs $12 to $25 per day.
Before you buy the rental company's waiver, check whether your own auto insurance or credit card already covers rental cars. Many policies do, which means paying for the waiver twice. Call your insurance company or credit card issuer before you book. If you are not covered, the rental company's waiver is usually cheaper than paying out of pocket for repairs.
If you damage the car, report it to the rental company when ready — do not try to hide it. Take photos of the damage and get a written statement from the agent. If the damage is minor, the company may not charge you even without a waiver, depending on their policy. Major damage will result in a claim against your deductible or, if you have no waiver, against your credit card and your own insurance.
How to compare rental companies and find the best rate
The major national chains — Enterprise, Hertz, Budget, Avis, and National — operate at most airports and cities. Regional companies like Turo (peer-to-peer car sharing) and local independent agencies often charge less but may have fewer locations and stricter cancellation policies. Use a comparison site like Kayak, Autoslash, or Priceline to search multiple companies at once, but always verify the final price on the company's own website before booking.
Rates fluctuate based on demand, season, and how far in advance you book. Booking two to three weeks ahead usually yields better prices than booking the day before. If you are renting during peak season (summer, holidays, spring break), book as early as possible. Conversely, last-minute rates sometimes drop if a rental location has excess inventory.
Compare the total cost, not just the daily rate. A company quoting $35 per day might charge $80 per day once you add the damage waiver, airport fee, and taxes. Another company quoting $50 per day might total $65 with everything included. Read the cancellation policy too — some companies charge a fee if you cancel within 24 hours, while others offer free cancellation up to the rental date.
What happens at pickup and what to inspect before you drive
When you arrive at the rental counter, bring your driver's license, credit card, and proof of insurance. The agent will run your license, place a hold on your credit card for the security deposit, and ask you to sign a rental agreement. Read the agreement before you sign — it outlines your liability, the damage waiver terms, and any restrictions on where you can drive the car.
Before you leave the lot, walk around the car with the agent and inspect it together. Point out every scratch, dent, and stain — the agent will note these on the contract so you are not charged for pre-existing damage. Take photos or video of the car's condition with your phone. Check that the spare tire, jack, and basic tools are in the trunk. Test the lights, wipers, and air conditioning. If anything is broken or missing, tell the agent when ready.
Ask about mileage limits. Most rentals include unlimited mileage, but some budget companies cap mileage at 100 or 150 miles per day, charging $0.25 to $0.50 per mile over the limit. Confirm the fuel policy in writing — whether you prepaid for a full tank or whether you need to return it full.
Returning the car and avoiding surprise charges
Return the car on time. Late returns are charged at the daily rate or a higher hourly rate, and a car returned even 30 minutes late can trigger a full extra day's charge. If you are running late, call the rental location and ask whether they can extend your reservation — sometimes they can waive the late fee if you call ahead.
Return the car with a full tank of fuel if you did not prepay. Fill up at a gas station near the rental location, not at the airport or in a tourist area where prices are highest. Keep your receipt. Return the car to the same location where you rented it unless you booked a one-way rental, which costs extra.
The agent will inspect the car for damage and check the mileage and fuel level. If there is new damage, the company will photograph it and send you a claim. The security deposit hold on your credit card will be released within three to five business days, though some companies take longer. If you used the rental company's insurance, any claims will be deducted from the hold before it is released.
Frequently Asked Questions
Can I rent a car with a debit card instead of a credit card?
Most major rental companies require a credit card because they need to place a security deposit hold. Some regional companies and peer-to-peer services accept debit cards, but they may require a larger deposit or charge a higher daily rate. Call the rental company directly to ask — do not assume based on their website.
What if I get into an accident while renting?
Call the rental company when ready and report the accident, even if it is minor. Do not admit fault or sign anything except the police report. Take photos of the damage, get the other driver's insurance information, and file a police report if anyone is injured. The rental company will file a claim with their insurance or charge you based on your damage waiver and deductible.
Is it cheaper to rent from an airport or downtown location?
Downtown and off-airport locations are usually 15 to 25 percent cheaper because they do not pay airport concession fees. However, if you are flying in and out, the time and transportation cost to reach an off-airport location may offset the savings. Compare the total cost including ground transportation before deciding.
Can I extend my rental after I pick up the car?
Yes, most companies allow extensions if the car is available. Call the rental location and ask — they may extend at the same rate or charge a higher rate depending on demand. Extending online through the company's website is usually faster than calling.
What happens if I return the car with damage I did not cause?
If you have a damage waiver, you pay only the deductible. If you do not have a waiver, you are liable for the full repair cost unless you can prove the damage was pre-existing. This is why inspecting the car at pickup and taking photos is critical — your photos are your proof.
