Updated October 17, 2026. We rechecked this guide against the rental terms posted by Enterprise (Caribe Hilton branch), Avis, Budget, NÜ Car Rentals and Finalrentals, the official SJU airport site, Puerto Rico Ferry, AutoExpreso and the DTOP toll page, and CESCO's April 2026 summary of the traffic law. Rental terms change often, so treat the dollar figures below as examples from those pages and confirm your own contract. This is trip advice, not legal or insurance advice.
Most visitors who leave the San Juan metro rent a car. Uber and Lyft both work in Puerto Rico (Lyft launched island-wide on July 8, 2025), and they are easiest to use around San Juan. West-coast beaches, mountain towns and full-day loops are car country. If you plan to stay in one resort area and book tours, you can skip the rental. If you want your own schedule around the island, budget for one.
Do you need a car?
| Trip style | Car? | Why |
|---|---|---|
| Old San Juan + Condado / Isla Verde hotels, restaurants, beach days | Often no | Walking, hotel shuttles and Uber or Lyft cover most of it |
| Day trips to El Yunque, Luquillo, Fajardo bio-bay pickups | Helpful | Early starts, parking at trailheads and late returns are simpler with your own wheels |
| Rincón, Aguadilla, Isabela, the south coast, mountain towns | Yes | Rideshare gets sparse and slow out here; public transit won't replace a car |
| Outer islands (Vieques, Culebra) | Rent on the island | Puerto Rico Ferry won't sell a vehicle ticket for a rental car, so leave the mainland rental behind and book a jeep or golf cart on the island |

Picking up at the airport or in town
Luis Muñoz Marín (SJU) has the most choice. The airport's own rental page lists Avis, Budget, Enterprise, Alamo, National, Thrifty, Hertz, Charlie Car Rental, Sixt, Cabrera Car & Truck Rental and Easeway. Some counters are in the parking garage across from arrivals (Avis says its desk is on the garage's first floor and open 24 hours); others meet you at a shuttle stop outside baggage claim. Your confirmation email tells you which.
Aguadilla (BQN) and Ponce (PSE) are smaller. Avis runs a BQN branch, and at PSE the Avis and Budget counters are inside the terminal, a short walk from the cars. Hours can be limited: Budget's PSE desk posts 8 AM–4 PM plus an overnight window. Some brands at BQN work through a local partner that picks you up after you call, so keep your phone charged when you land. Reserve early if your trip starts on the west or south coast.
In-town branches in Isla Verde, Condado or Old San Juan can save you a few days of rental (and parking) if you spend your first nights car-free. Check the hours first: the Enterprise desk at the Caribe Hilton, for example, posts 8 AM–5 PM, closed Sundays, with no after-hours returns. Locally owned Charlie Car Rental, in business since 1982, rents from an office at 874 Ashford Avenue in Condado and offers shuttle rides from the cruise ship area or your hotel. Beyond San Juan, Enterprise has town branches in Ponce (Avenida La Ceiba) and Dorado (Dorado del Mar Shopping Center). Both will pick you up, and like the Caribe Hilton desk, neither takes returns after closing.

Age, license and payment
- Age 21 is the usual floor at the big brands. At Enterprise's Caribe Hilton branch, every driver must be 21 or older, drivers aged 21–24 pay a $25-a-day surcharge, and they're limited to economy-through-full-size cars, minivans, pickups and five-seat SUVs.
- Some local companies rent from 18, with conditions. NÜ Car Rentals' Aguadilla terms accept drivers aged 18–20 who bring their own insurance that covers Puerto Rico ($19.95 a day extra) and charge $9.95 a day for ages 21–24. The same terms set higher minimums for some classes: 25 for midsize and larger cars, SUVs, minivans and trucks, and 30 for convertibles. Finalrentals also lists an 18-to-75 age range.
- Bring the physical license. Enterprise only accepts a digital license if it's Puerto Rico's own CESCO app license, so visitors from the mainland need the plastic card, valid for the whole rental.
- Visitors from abroad: bring your home-country license. Enterprise calls an International Driving Permit a translation, not a license: it's recommended when your license is in another Latin-alphabet language, required when it uses a different alphabet, and never enough on its own. You may also be asked for your passport.
- Use a credit card in the renter's name. Deposit holds vary: Enterprise's Caribe Hilton branch lists $200 ($850 for luxury classes), NÜ lists $200 to $1,000 depending on the car and your coverage, and Finalrentals lists $500 to $1,000. Debit cards come with strings. Enterprise wants address-matching bills and pay stubs, and NÜ only takes Visa or Mastercard debit cards with your name raised on the card.
Insurance: counter waiver vs your own coverage
The counter will offer a collision or loss damage waiver plus extra liability cover. Prices on the pages we checked: Enterprise's Caribe Hilton waiver runs $21.99–$25.99 a day and is optional there; Finalrentals' runs $19.95–$29.95 a day.
Some Puerto Rico counters require the waiver unless you can prove other coverage. NÜ's Aguadilla terms, for example, make it mandatory unless your credit card extends rental collision cover to Puerto Rico or you show written proof of a policy that does. Those terms also say reimbursement-style coverage isn't accepted, and they may ask for a benefits letter and proof that you booked with the same card. Before you fly, call your card issuer and your insurer, ask specifically about Puerto Rico, and get the answer in writing. If you decline the counter product, film a slow walk-around of the car at pickup and keep every page of the contract.
AutoExpreso tolls
Puerto Rico's toll roads run on AutoExpreso, a prepaid electronic system: a windshield sticker is read as you drive through, and the toll comes out of a prepaid account. There's nowhere to pay a toll in cash. The lanes marked "R" at some plazas exist to sell and top up AutoExpreso accounts, and the newer open-road gantries have no booths at all.
What renters actually do: ask the desk how tolls work on your car before you drive off. Many companies sell a daily toll pass. NÜ and Finalrentals both charge $5.95 a day, and both exclude the Teodoro Moscoso Bridge and the dynamic toll lanes (DTL), so those get billed separately. Opening your own resident AutoExpreso account is rarely worth it for a short trip.
Skip the pass and you still pay. Unpaid tolls stay tied to the car's plate, and the rental company bills them back with its own fees. Finalrentals, for example, charges $150 plus the toll if you drive a toll road without its pass. For route times, see how long it takes to drive around Puerto Rico and the driving distance chart.
Parking in Old San Juan and beyond
Old San Juan is the hard part: narrow one-way streets, cruise-day crowds and very little curb space. Head for a paid garage, then walk. Condado gets similar on busy evenings, and a hotel or paid lot beats circling Ashford Avenue.
The traffic law's basics apply everywhere. Park on the right-hand side of the street, no more than 12 inches from the curb. Never double-park or stop on a crosswalk. CESCO's summary lists fines of $50 for parking on a yellow line, $200 on a sidewalk and $1,000 in a disability space without a permit. Outside the metro, beach and town lots are easier. Wherever you park, leave nothing visible inside.
Rules of the road
- Drive on the right, as on the U.S. mainland.
- Speed limits are in miles per hour, but distances are in kilometers, and gas is priced by the liter. Unless signs say otherwise, the limits are 25 mph in urban areas, 45 mph in rural areas and 65 mph on qualifying expressways. School zones drop to 15 mph in towns and 25 mph in the country.
- Speeding gets expensive: $100 plus $10 for every mph over the limit, and $200 plus $10 per mph in a school zone. Driving without your license on you is a $50 fine.
- Seat belts for everyone ($100 per unbelted occupant). Children under 4 ride in a car seat in the back. Kids aged 4 to 8, or anyone 4 feet 9 inches or shorter, need a booster seat. Children 12 and under sit in the back unless the vehicle only has front seats. Rental desks rent child seats (NÜ lists $8.99 a day).
- Alcohol limits: 0.08% blood alcohol for most drivers and 0.02% for drivers under 21, even though the drinking age is 18.
- Red lights between midnight and 5 AM: the law lets you stop, check that the way is clear, and then go on through. Use this carefully, and only where it's safe.
- Road signs are often in Spanish, so learn a few words before you go: salida (exit), peaje (toll), despacio (slow).
- Mountain and rural roads are narrow, steep and sometimes potholed. Give yourself extra time, use the horn on blind curves, and avoid unfamiliar mountain roads after dark if you can.
Safety habits that matter
- Leave nothing of value in the car. Beach parking is a classic setting for break-ins.
- Lock up, park in busy, well-lit lots at night, and keep phones and bags off the seats.
- Drive defensively. Expect sudden lane changes on expressways and fewer turn signals than you may be used to.
Island-wide context: Is Puerto Rico safe?
Practical checklist
- Decide car vs rideshare from your real itinerary: metro-only or island loop.
- Book early for holidays and high season, and screenshot the age, deposit and toll rules for your exact branch.
- Call your card issuer and insurer about Puerto Rico coverage and get it in writing.
- At pickup, film the car, confirm the fuel policy and the toll product, and note every scratch on the form.
- Budget for garage parking on Old San Juan days.
- Return the car with the agreed fuel level and keep your receipts.
FAQ
Do I need a rental car in Puerto Rico?
Not for a San Juan-and-tours trip. Yes for most self-drive itineraries around the island.
Can I rent a car under 25?
Usually from 21 at the big brands, with a daily young-driver fee and limits on car classes. A few local companies rent from 18 if you bring insurance that covers Puerto Rico.
Can I take my rental car to Vieques or Culebra?
No. Puerto Rico Ferry doesn't sell vehicle tickets for rental cars, and some rental contracts bar leaving the main island anyway. Rent a jeep or golf cart on the island instead.
Do I need cash for tolls?
No. Tolls are electronic (AutoExpreso). Ask for the rental company's toll pass and check whether it covers the Teodoro Moscoso Bridge and the dynamic toll lanes.
Can I just use Uber?
Inside the San Juan metro, yes. For west, south and mountain days, rides get sparse and return trips aren't guaranteed. See Uber and Lyft.
