Where to rent a car in San Juan

San Juan has rental desks at Luis Muñoz Marín International Airport (SJU), in Old San Juan, and at several hotels and resorts. The airport location is the most straightforward if you're arriving by plane — you'll find rental counters in the baggage claim area, and you can pick up your car before leaving the terminal. If you're already in the city, street-level offices in Old San Juan and Condado offer walk-in rentals, though these typically have higher daily rates than airport locations.

Major companies operating in San Juan include Hertz, Avis, Budget, Enterprise, and Thrifty, along with local operators like Vroom and Nelly Car Rental. Prices and vehicle availability vary significantly between companies and by season — winter months (December through March) are peak tourist season and rates are highest. Booking online before arrival usually costs less than renting on the spot, and you can compare rates across companies on travel sites like Kayak, Priceline, or directly through each company's website.

Key Takeaways

  • Airport rentals are cheaper and more convenient than street-level offices, and you can pick up your car when ready after landing.
  • You need a valid driver's license from your home country or an International Driving Permit, a credit card in your name, and proof of insurance coverage.
  • Puerto Rico requires all drivers to carry a valid license and proof of insurance at all times, and traffic laws follow US standards with some local variations.
  • Rental rates in San Juan range widely by season and company, so booking online in advance typically saves money compared to walk-in rates.
  • Driving in Old San Juan itself is difficult due to narrow streets and limited parking; many visitors rent for day trips outside the city instead.

What documents you need to rent a car

You'll need a valid driver's license from your home country — Puerto Rico recognizes licenses from all US states and most foreign countries. If your license is not in English or uses a non-Latin alphabet, bring an International Driving Permit (IDP) as well, which you can obtain from your home country's automobile association before traveling. The rental company will check your license against their system to verify you have a clean driving record in Puerto Rico.

You must also present a credit card in your own name — debit cards are not accepted for the deposit hold. The rental company will place a hold on your card (typically $200 to $500 depending on the vehicle) that is released when you return the car undamaged. Bring proof of insurance: either your personal auto insurance card from home or a rental car insurance policy you've purchased separately. If you don't have coverage, the rental company will sell you a damage waiver, which costs $15 to $30 per day depending on the vehicle type.

Insurance and damage coverage options

Puerto Rico law requires all drivers to carry liability insurance. When you rent, you have three coverage routes: use your personal auto insurance from home (if it covers rentals), purchase a separate rental car insurance policy before arrival, or buy the rental company's damage waiver at pickup. Check your personal policy first — many US auto insurance plans cover rental cars, but some exclude Puerto Rico or charge extra. Call your insurer before your trip to confirm what's covered.

If your personal insurance doesn't cover rentals in Puerto Rico, you can buy a standalone policy from companies like Allianz or World Nomads for $5 to $15 per day, often cheaper than the rental company's waiver. The rental company's damage waiver typically costs $15 to $30 per day and covers collision, theft, and vandalism but usually has a deductible of $500 to $1,000. Read the fine print on any waiver — some exclude damage from driving on unpaved roads or off-road use, which matters if you plan to explore rural areas.

Driving laws and requirements in Puerto Rico

Puerto Rico follows US traffic laws with some local differences. The speed limit on highways is 65 mph, on regular roads 45 mph, and in residential areas 25 mph — these are enforced by the Puerto Rico Police Department. You must carry your driver's license and proof of insurance at all times while driving; police can stop you for a routine check. Seat belts are mandatory for all passengers, and children under 12 must sit in the back seat.

Driving under the influence is illegal and carries the same penalties as in the US — a first offense can result in a fine, license suspension, and jail time. Traffic violations are recorded in the Puerto Rico system and may affect your driving record at home. Parking in San Juan is metered in many areas; pay attention to signs, as parking enforcement is active. Avoid driving in Old San Juan itself if possible — streets are narrow, one-way, and parking is scarce and expensive. Most visitors rent a car for day trips to El Yunque, Culebra, or other destinations outside the city.

Rental car costs and what affects the price

Daily rental rates in San Juan range from $30 to $80 for an economy car, $50 to $120 for a mid-size sedan, and $80 to $200 for an SUV, depending on the company, season, and how far in advance you book. Winter rates (December through March) are roughly 30 to 50 percent higher than summer rates. Booking online a week or more before arrival usually costs 20 to 40 percent less than booking at the counter. Local companies like Vroom and Nelly Car Rental often undercut the major chains by $10 to $20 per day.

Additional costs to budget for include gas (fill the tank before returning the car or pay inflated prices), tolls on some highways ($0.75 to $2.50 per toll), parking in the city ($2 to $5 per hour in metered areas), and any damage waiver or insurance you add. Some rental companies charge extra for drivers under 25 or over 75. If you're renting for more than a week, ask about weekly rates — they're often cheaper per day than daily rates. Check whether your rate includes unlimited mileage; some local companies cap mileage at 100 to 150 miles per day.

Picking up and returning your rental car

At the airport, follow signs to "Car Rental" after you collect your luggage. You'll go through a short line, show your documents, sign the rental agreement, and receive your keys — the whole process usually takes 10 to 15 minutes. The rental agent will walk you around the car to document any existing damage (dents, scratches, tire condition) on a damage report; take photos of the car yourself on your phone as backup. Make sure the agent notes any damage you see before you drive away — you won't be charged for it later.

When you return the car, plan to arrive at least 30 minutes before your flight or departure. The rental company will inspect the car for new damage, check the mileage and fuel level, and process your credit card. If you rented from the airport, return the car to the airport location — returning to a different location may incur a drop-off fee of $25 to $75. Keep your rental agreement and any receipts until you're home and your credit card statement reflects the final charge, in case there are disputes about damage or fees.

Frequently Asked Questions

Do I need an International Driving Permit if I have a US driver's license?

No. A valid US driver's license is sufficient to rent and drive in Puerto Rico. You only need an International Driving Permit if your license is from outside the US or is not in English.

Can I rent a car if I'm under 25?

Yes, but most companies charge an extra fee of $15 to $30 per day for drivers under 25. Some local companies have no age surcharge. Ask about the fee when you book or call ahead.

What happens if I return the car late?

Late fees typically start after a grace period of 30 minutes to one hour and cost $25 to $50 per hour or a full day's rental rate, whichever is higher. Return the car on time to avoid these charges.

Is it safe to drive in San Juan at night?

Stick to well-lit, populated areas and main roads. Avoid driving alone late at night in unfamiliar neighborhoods. During the day, driving is straightforward and safe on major routes like PR-52 and PR-22.

Can I take the rental car to other islands like Culebra or Vieques?

No. Rental cars cannot leave Puerto Rico. To visit Culebra or Vieques, you must return your rental car and take a ferry or small plane from San Juan.
