Tips for renting a car for cheap in San Juan

Can you use a cheap car rental in San Juan? With Economybookings, you can easily compare multiple providers to find the best deal. With so much to see and do in San Juan and across Puerto Rico, a quick comparison can save you time and money on a car that will help you reach it all.

• Compare pickup locations – Select the broader city instead of a specific location to unlock more deal options, including off-airport savings.
• Slightly adjust pickup times and dates – Even changing your booking by an hour can reveal lower rates.
• Choose economy or compact cars – If you’re planning road trips to rural areas and/or with large parties, it might make sense to select a larger four-wheel drive vehicle. Otherwise, a compact car is probably all you need to get around the San Juan metro region.
• Book early – Unlike most other Caribbean destinations, Puerto Rico tends to stay booked and busy year-round. Key periods include spring break (when many U.S. schools give students a week off), summer vacation season, and winter holiday festival season. Booking in advance helps secure lower prices and better vehicle selection.

Tips When Renting and Driving a Car in San Juan

• Rent a car if you plan to explore anywhere away from San Juan’s urban core, where public transport options may be limited.
• Avoid rush hour traffic on the PR-18 and PR-52 freeways.
• You can pick up your car at Luis Muñoz Marín International Airport (SJU) Airport and various storefronts in and around town.
• Choose a small car for better mileage and easier parking around town.
• Pick a car with four-wheel drive for longer drives into rural areas.
• Inspect the car and take photos before and after rental.

Driving Tips in San Juan

• Drive on the right side of the road, and prepare to wait your turn when you need to turn left.
• Look out for stop lights—green means go, yellow signals that you must prepare to stop, and red is stop. At most intersections with stop lights, there will also be dedicated stop lights for left-turn lanes.
• In some areas, you might run into roundabouts. To navigate these roundabouts, give way to traffic coming from the left.
• Puerto Rico law requires nighttime headlight use, as well as whenever visibility falls below 500 feet.
• Horn use should be reserved for emergencies or warnings.
• Traffic usually moves faster in the left lanes on highways.
• Expect to pay around $2-$3 per hour for guaranteed parking in popular neighbourhoods like Old San Juan and Condado. (Street parking is usually free, but it can be difficult to find available spaces.) Many lots accept credit cards, but it’s usually best to come prepared with cash.
• NEVER cross a set of double yellow lines.
• Try the GasBuddy app to locate area gas stations and check prices. If you have a Costco membership, you can refuel there and take advantage of their very cheap gas.
• Keep your driver’s license, rental papers, and proof of insurance with you at all times.
• Puerto Rico Highway 26 (PR-26), also known as the Román Baldorioty de Castro Expressway, is the main highway that connects central neighbourhoods like Old San Juan, Condado, and Santurce to Luis Muñoz Marín International Airport. PR-26 also connects to the PR-22 toll road that ventures west to Arecibo and Hatillo, the PR-18 and PR-52 freeways (also known as Expreso Las Américas) that go south to Caguas and Ponce, and the PR-3 highway that rings around the eastern coast of the main island.
• These major highways can be useful for reaching more of Puerto Rico, but expect heavy traffic during weekday rush hours (6:00 to 9:00 AM, and 4:00 to 7:00 PM).

Speed Limits

Within urban areas like San Juan, speed limits are generally 25 miles per hour (mph), or 40 kilometres per hour (km/h), unless otherwise noted. Meanwhile, on rural highways, the speed limits usually clock in at 43 mph (70 km/h). On multilane freeways, the speed limits usually reach 55-65 mph (or 89-105 km/h). In school zones, the maximum speed limit is 15 mph (25 km/h), and it’s most strictly enforced during pick-up and drop-off hours.

Road Signs

While Puerto Rico’s road signs mostly resemble those on the U.S. mainland, there are a few key differences. For one, signs are mostly in Spanish, though they also use standard U.S. road sign symbols for quick understanding. And while speed limit signs are in miles per hour (mph), distances are generally posted in kilometres per hour (km/h). Across Puerto Rico, look out for signs marking dedicated rail crossings, bus lanes, bike lanes, and school lanes, which may have special speed limits and other restrictions.

Tolls, Fees, and Restrictions

As of 2026, Puerto Rico has seven toll roads: PR-5, PR-17, PR-20, PR-22, PR-52, PR-53, and PR-66. Toll costs range from $0.35 to $5.00 per toll booth, and these toll booths sometimes slow to a crawl during rush hour. Fortunately, more of these toll booths are shifting to cashless express lanes with AutoExpreso, a RFID windshield transponder that can easily be attached to a car.

AutoExpreso electronic transponders are now sold at multiple gas stations across Puerto Rico, and customers can also utilize these locations to “pre-fill” and “refill” their AutoExpreso balances. (Money must be added to AutoExpreso in advance before using it.) Before you finish any plans for future road trips around Puerto Rico, check with your rental car agency in advance to see if they provide an AutoExpreso transponder, and ask about their toll road coverage policies.

Discover Puerto Rico by Car

Tourists love flocking to the historic landmarks of Old San Juan and the beautiful beaches of Condado, but there’s so much more to explore throughout Puerto Rico. While San Juan does have public buses and rapid transit trains, mass transit options are much more limited elsewhere. With a rental car, you can reach more places without having to stress over limited bus service and pricey Uber and Lyft rides.

Whether you're planning a day trip to experience the magic of El Yunque and Luquillo, or you fancy a longer drive to Cayey, Ponce, and the West Coast, a car offers flexibility and freedom to discover hidden spots that are much harder to reach via public transportation in the U.S.

When to Visit

Whenever you decide to visit Puerto Rico, you will run into certain benefits and drawbacks. During winter and spring, the weather is drier (or, at least, less rainy) and the festivals are aplenty, but this also means airfare and hotel rates may be much more expensive. On the flip side, the summer and fall months can be cheaper, but rainy days are much more frequent, and August, September, and October are usually the most active months of hurricane season.

Since Puerto Rico has a humid tropical climate, it’s always a good idea to prepare by packing umbrellas and ponchos, and by staying off the roads if severe storms approach. Whenever you plan to go, always check road conditions in advance for potential closures.

Languages & Communication

Unlike the mainland United States, Spanish is Puerto Rico’s primary language. Yet since San Juan regularly caters to tourists and has a growing population of Americans who have moved from the mainland, English is a generally accepted second language. At popular areas like Old San Juan and Condado, visitors rarely face language barriers. But in less tourist-heavy areas, it helps to know some Spanish.

Currency & Payments

Since Puerto Rico is part of the United States, the U.S. dollar ($, or USD) is used everywhere. Credit and debit cards are widely accepted, and contactless payments are becoming more commonplace. ATMs are easy to find throughout San Juan and its suburbs, but keep in mind that ATMs will charge extra fees if they are not affiliated with your bank.
