Vehicles can be picked up directly at Domingo Faustino Sarmiento International Airport (UAQ) or downtown from several local and international providers.

Renting a car in San Juan, Argentina is the most practical way to navigate both the urban center and the surrounding natural attractions of the province. This guide provides essential details on securing a vehicle, understanding local traffic laws, and avoiding common pitfalls. Whether you are arriving at Domingo Faustino Sarmiento International Airport (UAQ) or planning to pick up your vehicle in the downtown area, you will find options from several established agencies, including Avis, Budget, FlexWays, Rent A Car Argentina, Always Rentacar, and Street Rent a Car. Before booking, it is important to familiarize yourself with Argentina's specific driving requirements, such as mandatory safety equipment, daytime headlight rules, and varying provincial blood alcohol limits. Read on to learn about rental conditions, pick-up locations, and tips for driving across the border to Chile.

L'essentiel: Driving Rules and Requirements

To rent a car in San Juan, drivers must generally be at least 21 years old and hold a valid national driver's license for at least one year. However, certain providers like Flexways allow drivers aged 20 to rent a vehicle, subject to a young driver fee. A physical credit card in the main driver's name is strictly required to secure the safety deposit.

When driving, you must keep your dipped headlights (low beams) turned on 24 hours a day on all highways and main roads. Additionally, Argentine law mandates that every vehicle carries specific safety equipment: two reflective warning triangles, a fire extinguisher inside the cabin, a first aid kit, and a safety vest.

Speed limits are strictly enforced:

• Residential areas: 40 km/h
• Urban main roads: 60 km/h
• Rural roads: 110 km/h
• Expressways (autopistas): 120–130 km/h

Regarding alcohol limits, Argentina adopted a national zero-tolerance (0.00% BAC) law for federal roads in 2023. However, San Juan province is among the jurisdictions that historically retained a 0.05% BAC limit for private drivers on provincial routes. Because it remains unclear if the province has since fully transitioned to the 0.00% limit, drivers are advised to avoid alcohol entirely before driving.

Rental Prices and Booking Tips

While the exact average daily rental price for a basic manual sedan in San Juan is not publicly fixed for 2026, rates fluctuate based on seasonal demand and vehicle availability. To secure the best rates and ensure your preferred vehicle class is available, it is highly recommended to book your car hire in San Juan, Argentina well in advance.

When comparing offers, check what is included in the base rate. Most agencies require a physical credit card for the security deposit, and debit cards or cash are generally not accepted for this purpose. If you plan to share the driving duties, verify the fees for additional drivers. If you are under 21, factor in the young driver surcharge that providers like Flexways apply. Always inspect the vehicle at pick-up to ensure all legally required safety gear—including the fire extinguisher, safety vest, first aid kit, and two warning triangles—is present in the car before you leave the lot.

Pick-Up Locations in San Juan

The primary hub for picking up a rent a car in San Juan, Argentina is Domingo Faustino Sarmiento International Airport (UAQ). The airport is located in Las Chacritas, approximately 13 kilometers east of the city center, which is a straightforward 15-minute drive via Ruta Nacional 20.

Several rental providers operate directly at the airport or offer downtown pick-up services, including:

• Avis
• Budget
• FlexWays
• Rent A Car Argentina
• Always Rentacar
• Street Rent a Car

Picking up your vehicle at the airport is highly convenient for travelers arriving on domestic flights, allowing you to bypass local taxi queues and head straight to your destination. If you prefer to collect your vehicle in the city, several agencies maintain downtown offices. Be sure to confirm the operating hours of your chosen branch, as downtown locations may close during traditional afternoon siesta hours, unlike airport desks which generally align with flight schedules.

Cross-Border Travel to Chile

San Juan's proximity to the Andes makes it a tempting starting point for an international road trip to Chile. However, driving a rental car across the border requires careful preparation. You cannot simply drive a rental vehicle across the border without prior authorization.

To cross into Chile, you must request a special cross-border permit from your rental company at least 72 hours in advance. This permit is accompanied by mandatory additional liability insurance. The cost for this cross-border authorization typically ranges between $80 and $200 USD, depending on the rental provider and the duration of your trip.

Keep in mind that not all car rental companies in San Juan permit cross-border travel, and some may restrict it to specific vehicle classes (such as 4x4s). Always verify this policy with your chosen provider before finalizing your booking if you plan to cross the Andes.
