What you need to rent a car in Miami
To rent a car in Miami, 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 an extra daily fee for drivers under 25. Your license can be from any U.S. state or an international license if you're visiting from abroad — bring your passport as well if you're not a U.S. citizen.
The credit card must be in the same name as the driver on the rental agreement. Rental companies use it to hold a deposit, which is typically released after you return the car undamaged. Debit cards are rarely accepted for this hold, even if you have enough money in the account. Your proof of insurance can be a physical card, a digital copy on your phone, or a letter from your insurance company — call ahead if you're unsure what your provider will accept.
Key Takeaways
- You must bring a valid driver's license, a credit card in your name, and proof of insurance to complete a rental.
- Miami has rental desks at Miami International Airport (MIA), Fort Lauderdale-Hollywood International Airport (FLL), and downtown locations, each with different pricing and wait times.
- Airport rentals cost more than off-airport locations because of facility fees, but you avoid a trip to a separate office.
- Damage waivers and additional insurance offered at the counter are often redundant if your personal or credit card policy already covers rental cars.
- Return the car on time and with a full tank to avoid late fees and fuel surcharges that can add $50 to $150 to your bill.
Where to rent in Miami: Airport versus off-airport locations
Miami International Airport (MIA) has rental desks for most major companies — Enterprise, Hertz, Budget, Avis, and National — in the rental car facility on the ground level. Fort Lauderdale-Hollywood International Airport (FLL), about 30 miles north, also has rental counters and sometimes offers lower rates because fewer tourists rent there. Both airports charge a facility fee on top of the daily rate, typically $5 to $15 per day depending on the company.
Off-airport locations in downtown Miami, Coral Gables, and along Biscayne Boulevard have no facility fee and often lower daily rates. The trade-off is that you must travel to the location yourself or arrange a ride, which takes time and costs money if you're arriving by plane. If you're staying in Miami for several days and don't need a car when ready, renting from an off-airport location can save $30 to $100 over a week-long rental.
Check the rental company's website directly before booking through a third-party site. Companies sometimes offer loyalty discounts, corporate codes, or local promotions that don't appear on aggregator sites. Call the specific location you plan to use — rates and vehicle availability vary by branch.
Understanding the daily rate and what's included
The advertised daily rate covers the vehicle and basic liability insurance required by Florida law. It does not include taxes, facility fees, or optional add-ons. Florida sales tax on car rentals is 7%, and Miami-Dade County adds a 2% rental surcharge, so expect the final bill to be roughly 9% higher than the quoted rate before fees.
Mileage is usually unlimited on Miami rentals, but confirm this when you book — some economy car deals cap mileage at 100 or 150 miles per day. If you plan to drive to the Florida Keys or up the coast, unlimited mileage matters. A one-way rental (picking up in Miami and dropping off elsewhere) costs more and may require a drop-off fee of $50 to $200 depending on distance.
The basic liability insurance covers damage you cause to other vehicles or property, but not damage to the rental car itself. That protection comes from a damage waiver, which you can purchase at the counter or bring from your own insurance policy.
Damage waivers and insurance: what you actually need
Rental companies offer a damage waiver (also called a collision damage waiver or CDW) at the counter, usually $15 to $30 per day. This waiver removes your financial responsibility if the car is damaged, stolen, or totaled. Before you buy it, check whether your personal auto insurance or credit card already covers rental cars — many do, and paying twice is wasted money.
Call your insurance company or credit card issuer before you rent and ask specifically: "Does my policy cover damage to a rental car in Florida?" Write down the name of the person who answered and the date. If they say yes, bring that confirmation in writing to the rental counter. If your policy covers rentals but has a deductible (often $500 to $1,000), you can choose to buy the waiver to eliminate that out-of-pocket cost.
Some credit cards cover rental damage automatically if you charge the entire rental to that card. American Express, Visa Signature, and Mastercard Black often include this benefit, but coverage limits and exclusions vary. Read your card's rental car benefits document or call the number on the back of your card to confirm before you arrive.
Booking online versus at the counter
Booking online locks in a rate and guarantees a vehicle type (economy, midsize, SUV), whereas booking at the counter means you pay the current rate and accept whatever is available. Online rates are almost always lower because companies use them to fill inventory. Reserve online even if you think you might change your mind — most bookings can be cancelled free of charge up to 24 hours before pickup.
Read the cancellation policy before you complete the booking. Some companies charge a fee if you cancel within 24 hours, and a few non-refundable rates cannot be changed or cancelled at all. If you book a non-refundable rate and your plans change, you lose the money, so stick with standard rates unless the discount is substantial enough to justify that risk.
When you arrive at the counter, the agent may offer upgrades, additional insurance, or roadside information packages. You are not obligated to buy any of these. Upgrades are sometimes free if the company is out of your reserved vehicle type, so ask before paying. Roadside information through your auto insurance or a membership like AAA is usually cheaper than the rental company's version.
Fuel, mileage, and return requirements
Most Miami rentals use a "full-to-full" fuel policy: you pick up the car with a full tank and must return it full. If you return it empty or partially empty, the company charges you for fuel at a per-gallon rate that is typically $2 to $4 higher than gas station prices. Fill up at a station near the rental location before you return the car — do not rely on the rental company's fuel service, which is expensive.
Return the car on the exact date and time stated in your agreement. Late returns incur daily charges that can be as high as the full daily rental rate, even if you're only an hour late. If you know you'll be late, call the rental company as soon as possible — they may extend your reservation at the standard rate rather than charging a late fee. Returning the car to a different location than you reserved may trigger a one-way fee or require you to pay a higher rate.
Inspect the car before you drive away from the rental lot. Take photos or video of any existing damage — dents, scratches, stains, or mechanical issues — and point them out to the agent. Ask them to note the damage on your rental agreement. This protects you from being charged for damage you didn't cause when you return the car.
Driving in Miami: insurance and traffic rules
Florida requires all drivers to carry liability insurance, and rental companies include basic coverage in the rental rate. However, you are responsible for any damage to the rental car unless you purchase a damage waiver. Uninsured motorist coverage (which protects you if hit by an uninsured driver) is not included in the basic rental rate and must be purchased separately if you want it.
Miami traffic is heavy, especially on Interstate 95, the Palmetto Expressway, and Biscayne Boulevard during rush hours (7–9 a.m. and 4–7 p.m.). Speed limits on highways are 65 to 70 mph, and Florida enforces them. Parking in Miami is metered downtown and in popular areas; read signs carefully to avoid tickets. Many hotels and attractions charge for parking, so factor that into your budget.
If you're involved in an accident, call the police (911 if anyone is injured) and report it to the rental company when ready. Do not admit fault or sign anything except the police report. Take photos of all vehicle damage, the other driver's license and insurance information, and the scene. Provide the rental company with the police report number and the other driver's information.
Frequently Asked Questions
Can I rent a car if I'm under 25?
Yes, but most companies charge an additional daily fee of $15 to $25 for drivers under 25. Some companies have a minimum age of 21, others 18. Check the rental company's age policy when you book — the fee is often not shown until you enter your date of birth.
What happens if I return the car with damage?
If you purchased a damage waiver, the rental company covers the repair cost. If you didn't, you pay for repairs out of pocket, which can range from a few hundred dollars for minor dents to thousands for major damage. The company may also charge you a loss-of-use fee while the car is being repaired.
Do I need an international driver's license if I'm visiting from another country?
No, a valid license from your home country is accepted in Florida. Bring your passport as proof of identity. Some rental companies require an International Driving Permit (IDP) in addition to your home license — check with the company before you arrive.
Can I rent a car one-way from Miami to another Florida city?
Yes, most companies allow one-way rentals. You'll pay a drop-off fee that depends on the distance — dropping off in Tampa or Orlando typically costs $50 to $100 extra. Book the one-way rental online to see the total cost before you commit.
What if I need to extend my rental after I've picked up the car?
Call the rental company as soon as you know you need more time. If the car is available, they can extend your reservation at the standard daily rate. If the car is already booked for another customer, you may have to return it on time and rent a different vehicle, or you'll be charged a late fee.
