What you need to rent a car in Puerto Rico
To rent a car in Puerto Rico, you will need a valid driver's license from your home country or state, a passport or other government ID, and a credit card in your name. Most rental companies require you to be at least 21 years old, though some charge extra fees for drivers under 25. A few companies have a minimum age of 25 with no surcharge.
Your driver's license does not need to be a Puerto Rico license — a US state license, Canadian license, or most other country's license is accepted. An International Driving Permit (IDP) is not required but can be useful if your license is not in English or Roman characters. You will also need proof of insurance, which can come from your own auto policy back home, a credit card's rental coverage, or the rental company's insurance.
Have your rental confirmation number ready when you arrive, and know which location you booked — San Juan has multiple rental counters, and picking up from the wrong one can cause delays. Bring the credit card you used to reserve the car, as rental companies typically place a hold on it for the security deposit.
Key Takeaways
- A valid driver's license, passport, and credit card are the three documents every rental company requires, regardless of your age or home country.
- Drivers under 25 usually pay an extra daily fee, but some companies waive this for drivers 25 and older.
- Your own auto insurance or credit card rental coverage may cover a rental car in Puerto Rico, so check your policy before buying the rental company's insurance.
- San Juan airport has multiple rental counters, so confirm your pickup location when you book to avoid going to the wrong desk.
- Roads in Puerto Rico use US road signs and drive on the right side, but some rural roads are narrow and pothole-prone, so inspect your rental before leaving the lot.
Insurance and coverage options for rental cars
Puerto Rico rental companies offer several types of insurance at the counter: collision damage waiver (CDW), liability coverage, and personal effects coverage. CDW covers damage to the rental car itself if you hit something or the car is hit. Liability covers damage you cause to other vehicles or property. Personal effects coverage protects your belongings inside the car.
Before you buy any of these, check whether your own auto insurance covers rental cars — many policies do, even for rentals outside the US. Call your insurer before your trip and ask specifically whether Puerto Rico rentals are covered and what your deductible is. Credit card companies often provide rental car coverage too, but the terms vary widely; some cover only collision, others exclude certain drivers, and some have restrictions on car size or rental duration.
If your personal insurance or credit card does not cover rentals, or if you want lower deductibles, buy CDW from the rental company. Liability coverage is usually mandatory and may already be included in your rental rate, but confirm this when you pick up the car. Do not assume coverage exists — ask the rental agent to show you what is included in your quote before you sign.
Driving in Puerto Rico: rules, roads, and conditions
Puerto Rico uses the same road signs and traffic laws as the US mainland — you drive on the right side, stop signs are red octagons, and speed limits are posted in miles per hour. The speed limit on most highways is 55 mph, though some stretches are 45 mph or 65 mph. In towns and residential areas, limits drop to 25 or 35 mph. Police enforce speed limits actively, and fines are issued on the spot.
Seatbelts are required for all passengers, and child car seats are required for children under 12 or under 60 pounds. Texting while driving is illegal, and hands-free phone use is required. Driving under the influence carries the same penalties as on the mainland — arrest, license suspension, and fines.
Road conditions vary significantly. Major highways between San Juan, Ponce, and Mayagüez are well-maintained, but rural roads in the interior and on the coasts can be narrow, poorly lit, and potholed. Many roads lack shoulders, and some mountain roads have sharp curves and no guardrails. Inspect your rental car for damage before you leave the lot — take photos of any dents, scratches, or missing parts — because you will be charged for damage you did not cause if it is not documented.
Where to pick up and drop off rental cars
The largest rental car hub in Puerto Rico is San Juan's Luis Muñoz Marín International Airport (SJU), where Hertz, Avis, Budget, Enterprise, and several local companies have counters. Pickup and drop-off at the airport is convenient but often costs more than off-airport locations. Many companies also have branches in Old San Juan, Condado, and other neighborhoods, which can be cheaper and closer to where you are staying.
If you are flying into San Juan but staying elsewhere, consider whether it makes sense to pick up at the airport or rent from a location near your hotel. Airport pickups add a rental car facility fee to your bill, but you avoid a taxi or rideshare to get to an off-airport location. Some travelers rent for only part of their trip — for example, picking up a car in San Juan for a drive to Ponce, then dropping it off and using local transportation or taxis for the rest of the stay.
One-way rentals (picking up in one city and dropping off in another) are available but usually cost more than round-trip rentals. Dropping off at a different location than where you picked up may also trigger additional fees. Ask about one-way charges when you book, and factor them into your decision about whether to rent for your entire stay or just part of it.
Booking a rental car and comparing prices
Rental car prices in Puerto Rico fluctuate based on season, demand, and how far in advance you book. High season (December through March and summer school breaks) is more expensive than low season. Booking two to four weeks ahead usually gives you better rates than booking a few days before arrival, but prices can drop closer to your travel date if demand is low.
Compare prices across multiple companies using rental car search sites, but also check the companies' own websites — sometimes they offer direct-booking discounts. Local Puerto Rico companies like Vega Car Rental and Thrifty often undercut the major chains, especially for longer rentals. Read the fine print on each quote: some include unlimited mileage, others charge per mile; some include a tank of gas, others require you to return the car full or pay inflated fuel charges.
When you book, confirm what is included in your rate: insurance, GPS, child seat, tolls, and airport fees. Many quotes hide fees until checkout, so compare the final total, not just the daily rate. If you are a member of AAA, AARP, or a frequent-renter program, ask whether discounts explore — they often do, but you have to mention them when you book.
Tolls, parking, and additional costs
Puerto Rico has a toll system called PR-PASS on major highways. If your rental car has a PR-PASS transponder, tolls are deducted automatically and the rental company bills you later. If it does not, you pay cash at toll booths. Tolls range from about $0.75 to $3.00 per crossing, depending on the road. Ask the rental company whether your car has a transponder and how tolls will be charged.
Parking in San Juan and other cities can be expensive and difficult to find, especially in Old San Juan and Condado. Many hotels offer parking for a daily fee (often $10 to $20), and some include it free. Street parking in residential areas is usually free but may require a permit. Parking garages in downtown areas charge $2 to $5 per hour or $15 to $30 per day. If you are staying in a city, consider whether you really need a car for the entire stay, or whether you can rent it only for day trips.
Fuel is sold by the liter in Puerto Rico, not by the gallon, so prices look lower than on the mainland but are actually comparable. Most rental companies require you to return the car with a full tank or charge you a premium for fuel. Fill up at a gas station before you return the car — it is always cheaper than the rental company's fuel charge.
What to do if you have an accident or damage
If you are in an accident, call the police (911) and wait for an officer to arrive. Get the other driver's name, phone number, address, driver's license number, license plate, vehicle make and model, and insurance company. Take photos of all vehicle damage, the accident scene, and the other driver's documents. Do not admit fault or sign anything except the police report.
Call your rental company when ready and report the accident. Tell them you have a police report number and photos. If you bought the rental company's collision coverage, your claim should be processed through them. If you are relying on your own insurance or credit card coverage, contact your insurer or credit card company as soon as possible and provide them with the police report and photos.
For minor damage discovered after you return the car, the rental company will contact you with photos and a damage claim. If you documented the car's condition with photos when you picked it up, you can dispute charges for damage that was already there. Keep your rental agreement and all receipts until your credit card statement arrives, in case you need to dispute a charge.
Frequently Asked Questions
Do I need an International Driving Permit to rent a car in Puerto Rico?
No, an International Driving Permit is not required. Your valid driver's license from your home country or US state is sufficient. An IDP can be helpful if your license is not in English or uses non-Roman characters, but rental companies will accept your home license alone.
Can I rent a car if I am under 21?
No, you must be at least 21 years old to rent a car in Puerto Rico. Most companies charge an extra daily fee for drivers under 25. Some companies have a minimum age of 25 with no surcharge, so call ahead if you are in that age range.
What happens if I return the car late?
Late returns are charged at a daily rate, which is usually higher than your original rate. Some companies charge an hourly rate for returns a few hours late. Check your rental agreement for the exact late-return policy, and call the rental company if you think you will be late so they can note it on your reservation.
Is my US auto insurance valid for a rental car in Puerto Rico?
Many US auto insurance policies cover rental cars, including those in Puerto Rico, but not all do. Call your insurer before your trip and ask specifically whether Puerto Rico rentals are covered, what your deductible is, and whether collision and liability are both included. This will help you decide whether to buy the rental company's insurance.
Can I drive a rental car from Puerto Rico to the US Virgin Islands?
No, you cannot drive a rental car from Puerto Rico to the US Virgin Islands because there is no bridge or road connection — you must take a ferry or flight. Most rental companies prohibit taking cars off the island anyway. If you want to visit the Virgin Islands, return your rental car and book a separate rental there.
