Renting a car in Puerto Rico is straightforward if you meet the key requirements: you must be at least 21 years old (25 to avoid young renter fees), possess a valid driver's license from your country of residence, and have a major credit card in the driver's name. Debit cards are often not accepted for the initial hold. The process is similar to the mainland U.S., but being a U.S. territory means your domestic license is sufficient; an International Driving Permit is not required. Essential Requirements and Costs The most critical step is ensuring you have the correct documentation. Beyond your license, a major credit card is non-negotiable for the security deposit hold, which can be several hundred dollars. Renting from a location outside the Luis Muñoz Marín International Airport (SJU) can sometimes help you avoid additional airport concession fees. It's also highly recommended to book your rental well in advance, especially during peak tourist season from December to April. | Rental Consideration | Key Details | Why It Matters | | :--- | :--- | :--- | | Minimum Age | 21 years old; under-25 fees apply for ages 21-24. | Prevents surprises; budgets for additional daily fees. | | Driver's License | Valid license from your country of residence. | An International Driving Permit is not legally required. | | Payment Method | Major credit card in the driver's name. | Debit cards are rarely accepted for the initial hold. | | Mandatory Insurance | Liability Insurance (SLI) is required by law. | This is automatically included in your rental quote. | | Optional Insurance | Collision/Loss Damage Waiver (LDW) is optional. | Check if your personal auto insurance or credit card provides coverage. | Insurance and Local Driving Tips You will automatically be charged for the mandatory liability insurance. The Collision Damage Waiver (CDW or LDW) is optional but strongly considered. Before accepting it, verify coverage with your personal auto insurer or credit card provider. When driving, be prepared for occasional potholes, narrow roads in older cities like Old San Juan, and toll roads (using an automated AutoExpreso tag, usually included with the rental). Always purchase a full tank of gas from the rental company and return it full to avoid high refueling charges.

Book online way before you go. The good cars sell out fast, and prices skyrocket if you wait. Make sure the name on your booking matches your driver's license exactly. When you pick it up, they’ll try to upsell you on extra insurance. Be ready to say "no" if you’re already covered. And seriously, get the full insurance coverage they offer if your own policy doesn’t extend to rentals—it’s better to be safe. Take a video of the car, noting every scratch, before you drive off.

The biggest hurdle for most visitors is the credit card requirement. They need to put a hold of several hundred dollars, and a debit card just won't work for that. Also, be aware that if you're between 21 and 24, you'll be charged a "young renter fee" every day, which can add up. My advice is to use a comparison site to see all your options at once. Don't just go with the first company you recognize; sometimes the local agencies have better rates for the same car.

From my experience, the best tip is to choose your pickup location wisely. Renting right at the San Juan airport is convenient, but you pay extra fees for that convenience. If your hotel is in Condado or Isla Verde, it might be cheaper to take a taxi there and rent from a downtown branch. Also, insist on getting a car with the AutoExpreso toll tag. The tolls are electronic, and the rental company’s per-day fee for using their tag is much less stressful than getting billed for missed tolls later.

Focus on the vehicle itself. A small, economical car is great for city driving and parking in cramped spaces. But if you plan to explore the rainforest (El Yunque) or the west coast beaches, the extra power and clearance of a small SUV can make a big difference. Before you finalize the booking, check the mileage policy. Unlimited mileage is standard but always confirm. Finally, inspect the car thoroughly with a rental agent present. Note any existing damage on the rental agreement to avoid being charged for it when you return the car.
