Quick Summary:
- At 21 in Miami, car hire is usually allowed with a young driver fee.

- Check insurance options, deposits, and fuel rules before arriving at the desk.
Yes, you can often arrange car hire in Miami at 21, but the experience is a little different from hiring at 25 or older. In the US, many rental brands set the standard minimum age at 21, then apply a “young driver” surcharge to cover added risk. Some suppliers also restrict which vehicle classes are available to drivers aged 21 to 24. The key is knowing how the age bands work, what the fee usually covers, and what might change at the counter when you collect.
This guide breaks down the common rules you will meet in Miami, including age bands, expected surcharges, restricted vehicle groups, and practical steps that reduce surprises at pick up.
Minimum age for car hire in Miami, what “21” really means
In Miami, the question is rarely “can I hire at 21?”, it is “can I hire the car class I want, with the payment method I have, under that supplier’s rules?”. Many major suppliers will rent to drivers aged 21 and above, but they typically apply extra conditions for ages 21 to 24.
Those conditions can include a daily under‑25 fee, a larger security deposit, fewer vehicle categories to choose from, and stricter requirements around the main driver’s card and identity checks. Some desk agents will also verify return travel details and local address information more carefully for younger renters.

Age bands explained, 20, 21 to 24, 25+
Ages 20 and under: In most cases, standard car hire is not offered to drivers under 21 in Miami. There are occasional exceptions in the wider US, but they are specialist and not typical for leisure rentals. Assume you will need to be at least 21.
Ages 21 to 24: This is the main “young driver” band. You are usually eligible to hire, but you will almost always pay a young driver surcharge. You may also find restrictions on higher powered models, luxury brands, convertibles, and larger passenger vehicles. Some suppliers require the main driver to have held a full licence for a minimum period, commonly one year.
Ages 25 and over: At 25, young driver fees usually stop, and the widest set of vehicle categories becomes available. Deposits and payment rules can still apply, but age stops being the main limiter.
When you are 21 to 24, plan your trip with a little slack. If your first choice of vehicle category is not permitted, you may need to switch to a compact, intermediate, or standard vehicle class at a different price.
Under‑25 fees, what they are and how they show up
The under‑25 fee is normally a per day surcharge added to the base rental cost. It may appear as “young driver fee”, “underage fee”, or “age surcharge”. The amount varies by supplier, location, and sometimes by season, so the best approach is to treat it as a standard line item rather than a negotiable extra.
Important details to watch for:
How it is calculated: Typically per day, sometimes capped at a maximum number of days. If you are hiring for a week or more, the cap can materially change the total cost.
Tax on the fee: In Florida, taxes can apply to rental charges and add ons, which means the surcharge may be taxed as well.
Where it is disclosed: It can appear during the quote, in terms and conditions, or at the counter if eligibility is confirmed late. Always read the local Miami terms for the supplier and the specific pickup location.
Does it include anything? Usually it is purely a surcharge. It does not automatically include extra insurance cover, extra drivers, or upgrades.
If you want to compare different supplier policies for Miami airport rentals, it can help to review a supplier specific landing page. For example, see local availability and typical terms here: Payless car hire in Miami (MIA).
Restricted vehicle classes for drivers 21 to 24
Restrictions vary, but the pattern is consistent. Drivers under 25 often have access to everyday categories, but face limits on vehicles that are expensive to repair, high performance, or in high demand.
Commonly restricted categories include:
Luxury and premium: Higher value brands and trims may be limited to 25+.
Sports cars and convertibles: Convertibles are frequently age restricted in Florida markets.
Large SUVs and specialty vehicles: Full size SUVs and specialty models may not be available for 21 to 24.
People carriers and minivans: Some suppliers allow them with restrictions, others limit them to 25+. If you need three rows, check carefully before you commit. This page helps you focus on that specific need: Minivan hire in Florida (MIA).
Even where a category is permitted, inventory can be the deciding factor. If the category is oversold, younger drivers may be offered a different class rather than a high value substitute. It is one reason to keep your plans flexible, especially during peak Miami travel periods.
What to expect at the counter when you collect in Miami
For younger drivers, the collection process can feel more formal. Most delays happen because of documents and payment rules, not because of driving age alone.
Licence and ID checks: Bring your full driving licence and ensure it is valid for the entire rental. If your licence is not in Roman characters, you may need an International Driving Permit alongside the original licence, depending on supplier policy and how the licence is presented.
Matching names: The main driver’s name must match the reservation and the payment card. If you are travelling with family, do not assume a parent’s card can be used for a 21 year old main driver.
Credit card expectations: Many suppliers require a major credit card in the main driver’s name for the security deposit. Debit cards can be rejected or can trigger additional requirements. If you only have a debit card, check the payment policy in advance, because Miami airport counters can be strict.
Deposit size: The deposit is often higher for younger drivers. Make sure your credit limit can cover it plus any hotel holds and travel spending. A declined deposit can mean you cannot collect the vehicle.
Proof of return travel: Some suppliers ask for flight details at airport locations, particularly when a renter has an out of state or international address. Keep your itinerary accessible.
If you are collecting outside the airport, terms can differ. For example, Coral Gables is a common pick up area for city based rentals: Hertz car hire in Coral Gables.
Insurance, waivers, and why under‑25 renters should double check
Miami car hire pricing can involve multiple layers of cover and optional extras. Young drivers should check these points before arriving:
What your quote includes: Some rates include collision damage waiver style cover, others do not. Know whether you are arriving with cover included, or whether you are expected to choose coverage at the desk.
Excess and deductibles: Even where cover is included, there may be an excess. Understand what you would pay if the vehicle is damaged.
Credit card coverage: Some credit cards include rental cover, but policies often have restrictions for age, vehicle type, and country. Verify your card’s terms, and do not assume it replaces the supplier’s required protections.
Personal insurance: If you are visiting from the UK, your personal car insurance at home usually does not extend to US rentals. Travel insurance may include limited car hire excess cover, but it is not the same as the rental company’s liability requirements.
The practical approach is to know what is included, what is optional, and what is mandatory at the counter. That reduces pressure when you are tired after a flight and are asked to choose between several options.
Extra drivers, young driver rules, and sharing the driving
Extra driver policies vary by supplier, and under‑25 rules often apply to each driver, not only the main driver. If your travel companion is also 21 to 24, you may see an extra driver fee plus a young driver surcharge for that additional driver.
If one traveller is 25+ and another is 21, it can be cheaper and simpler for the 25+ traveller to be the main driver, provided they will actually drive and meet payment requirements. Do not list someone as the main driver if they will not be present at pick up, suppliers typically require the main driver to collect the vehicle.
Fuel, tolls, and add ons, the Miami specifics that catch people out
Fuel policy: Miami rentals commonly use “full to full”. Take a quick photo of the fuel gauge at collection and return, and refuel near the return location to avoid premium fuel charges.
Tolls: South Florida roads include tolls, and Miami visitors can easily encounter them. Suppliers may offer toll packages, or they may charge tolls plus an admin fee after the rental. Decide how you will handle tolls based on your likely routes, for example, airport to Miami Beach, Everglades trips, or driving towards Fort Lauderdale.
Sat nav and child seats: Consider whether you need them, but plan for counter availability. Many travellers use phone navigation, but ensure you have a mount and charging plan.
Vehicle inspection: Walk around the car, photograph any existing marks, and ensure they are recorded before you leave. This is especially useful for younger renters who may worry about disputes later.
Planning around Miami, airport versus nearby cities
Where you collect can influence price, inventory, and the speed of service. Miami International Airport is convenient, but busy at peak times. If you are also considering surrounding areas, it can help to compare with nearby hubs such as Fort Lauderdale, especially if your flights or accommodation are there: Car rental in Fort Lauderdale (FLL).
Whichever location you choose, the under‑25 rules tend to be consistent within a supplier, but day to day vehicle availability and counter workload can change your experience. Arriving with your documents ready and your expectations set makes the biggest difference.
