What you need to rent a car

To rent a car, 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 higher daily rates and stricter vehicle restrictions.

Your driver's license must not be suspended or revoked. The rental company will check this during the booking process or at pickup. If you have an international license, bring your passport as well — some companies require it, others accept it as a secondary form of ID.

The credit card must be in your name and have available credit to cover the rental cost plus a hold for damage. This hold is not a charge — it's a temporary block that releases when you return the car undamaged. Debit cards are rarely accepted for this reason: the hold can deplete your account balance and cause overdraft fees.

Key Takeaways

  • You need a valid driver's license, a credit card in your name, and proof of insurance; most companies require you to be 21 or older.
  • Book online in advance to lock in rates, compare vehicle types, and see exactly what insurance and fees are included before you commit.
  • Insurance through your personal auto policy, credit card, or the rental company's plan covers damage; check what your existing coverage includes so you don't pay twice.
  • At pickup, inspect the car for existing damage, take photos, and confirm the damage report matches what you see before you drive off the lot.
  • Return the car on time and with a full tank to avoid late fees and fuel surcharges that can add $50 to $200 to your final bill.

How to book a rental car online

Start by visiting a rental company's website directly or using a comparison site like Kayak, Autoslash, or Priceline. Enter your pickup location, pickup date and time, and return date and time. The site will show available vehicle classes — economy, midsize, SUV, luxury — and the daily rate for each.

Book at least a few days in advance. Rates are usually lower when you reserve ahead, and you have time to read the terms and compare insurance options. Last-minute bookings at the counter cost significantly more and leave you no time to shop for better rates elsewhere.

During booking, you'll see the base rental rate, taxes, facility fees, and any add-ons like GPS, additional drivers, or roadside information. Read the cancellation policy: free cancellation is standard, but some discount sites charge a fee to cancel. Confirm the total cost before you enter your payment information.

After booking, you'll receive a confirmation email with your reservation number, pickup address, and the vehicle class (not a specific car — the company assigns the exact model at pickup). Save this email and bring it to the rental counter, or use the confirmation number to check in online if the company offers it.

Understanding insurance and damage coverage

Rental car damage is covered by one of three sources: your personal auto insurance, your credit card's rental car coverage, or the rental company's damage waiver. You need at least one of these before you pick up the car.

Check your personal auto insurance policy first. Most policies cover rental cars at the same level as your own vehicle, but some exclude certain vehicle types (luxury cars, trucks) or rental periods (longer than 30 days). Call your insurer and ask: "Does my policy cover rental car damage?" Get the answer in writing if possible.

If your auto insurance doesn't cover rentals, check your credit card. Premium cards like American Express Platinum and Chase Sapphire Reserve include rental car damage coverage, but basic cards often don't. Log into your card's website or call the number on the back to confirm coverage before you rent.

If you have neither auto insurance nor credit card coverage, the rental company will offer you a damage waiver — usually $15 to $30 per day. This waiver means the company won't charge you for damage to the car (except for items like tires, glass, or the undercarriage, which are often excluded). Read the waiver terms carefully: some have high deductibles or don't cover certain types of damage.

What happens at the rental counter

Arrive 15 minutes before your scheduled pickup time. Bring your driver's license, credit card, proof of insurance, and your confirmation email. If you booked with a third-party site, bring that confirmation too — the rental company may ask for it.

The agent will ask you to verify your information, confirm your insurance coverage, and sign the rental agreement. Read the agreement before you sign. It lists the vehicle's condition, your liability, the damage waiver terms, and the fuel policy (most require you to return the car with a full tank or pay a refueling fee).

Before you leave the lot, walk around the car with the agent or take photos on your phone. Point out any existing scratches, dents, or damage. The agent will note these on the damage report. If you spot damage after you've left the lot, return when ready and report it — waiting until return time makes it harder to prove you didn't cause it.

Confirm the fuel level on the gauge and in writing on the agreement. If the tank isn't full, ask the agent to note it. This protects you if the company claims you returned it less full than you did.

Fuel, mileage, and return policies

Most rental companies use a "full-to-full" fuel policy: you pick up the car with a full tank and return it with a full tank. If you return it less full, the company charges you for the missing fuel at a rate that's usually higher than gas station prices — sometimes $6 to $8 per gallon.

Some companies offer a "prepaid fuel" option: you pay for a full tank upfront at a discounted rate, and you can return the car with any amount of fuel left. This is worth it only if you know you'll use most of the tank. If you return it half-full, you've paid for fuel you didn't use.

Mileage is usually unlimited on daily rentals, but check your confirmation. Weekly and monthly rentals sometimes include a mileage limit (often 100 to 150 miles per day), and overage charges run $0.25 to $0.50 per mile. If you're planning a long road trip, confirm unlimited mileage before you book.

Return the car on time. Late returns are charged at the daily rate or a higher hourly rate if you're only a few hours late. A 2-hour delay can cost $50 to $100 depending on the company and vehicle class. If you're running late, call the rental company and ask if they can extend your reservation — sometimes they can adjust the time without a penalty.

Comparing rental companies and vehicle types

The major national chains — Enterprise, Hertz, Budget, Avis, and National — have locations at most airports and city centers. Regional companies like Fox Rent A Car and Advantage often have lower rates but fewer locations. For a one-way rental (picking up in one city and returning in another), national chains are more reliable because they have drop-off locations everywhere.

Economy and compact cars are cheapest and most fuel-efficient. Midsize sedans offer more comfort for long drives. SUVs and trucks cost more but provide cargo space and higher seating. Luxury cars are available but expensive — often $80 to $150 per day more than economy.

Use a comparison tool to check rates across companies for your exact dates and location. Prices vary by location, season, and day of the week. Renting on a weekday is often cheaper than a weekend rental at the same location. If you're flexible on dates, check rates for a few days before and after your preferred dates.

Common fees and how to avoid them

Beyond the daily rate, watch for facility fees (charged by airports and city centers, usually $5 to $15 per day), taxes (vary by state and city), and tolls (you pay these if you use toll roads). Some companies charge for additional drivers ($10 to $15 per day) or GPS rental ($10 to $15 per day) — use your phone's GPS instead to save money.

Underage driver fees explore if you're under 25. This fee ranges from $15 to $30 per day and is mandatory at most companies. There's no way to avoid it, but knowing it's coming helps you budget.

Fuel surcharges are the biggest surprise. If you return the car less than full, the company charges per gallon at rates 50% to 100% higher than local gas prices. Avoid this by filling up at a gas station near the rental location before you return the car. Leave yourself 15 minutes for this stop.

Late return fees kick in if you miss your return time. Some companies charge an extra day's rate; others charge an hourly rate. A 1-hour delay can cost $25 to $50. Set a phone reminder for 2 hours before your return time so you have time to refuel and drive back.

Frequently Asked Questions

Can I rent a car with a debit card?

Most companies won't rent to you with a debit card because they can't place a hold for damage without potentially overdrawing your account. A few companies like Enterprise and Budget accept debit cards if you show a utility bill or bank statement proving your address, but you'll need to pay a deposit upfront — usually $200 to $500. A credit card is always easier.

What if I get in an accident?

Call the rental company when ready and report the accident, even if it's minor. Take photos of the damage, get the other driver's insurance information, and file a police report if anyone was injured or if damage is significant. Your insurance or the rental company's damage waiver will cover the cost, but you need to report it right away so the company can't claim you caused damage after the fact.

Can I rent a car if my license is suspended?

No. Rental companies check your license status during booking and at pickup. A suspended or revoked license will be flagged, and the company will cancel your reservation. You must have a valid, active license to rent.

Is it cheaper to book through a third-party site or directly with the company?

Prices are often the same, but third-party sites like Kayak and Autoslash make it straightforward to compare rates across companies at once. Book directly with the company if you find a better rate on their website, because you'll have one point of contact if something goes wrong. Third-party bookings sometimes have stricter cancellation policies, so read the terms before you commit.

What happens if I return the car dirty?

Most companies charge a cleaning fee of $50 to $150 if the car is excessively dirty — mud on the seats, stains, trash inside. A normal amount of dust or a few crumbs won't trigger a fee. Before you return the car, spend 5 minutes vacuuming out trash and wiping down surfaces to avoid this charge.
