Car Rental in Buenos Aires, Argentina: A Practical Guide

This guide covers essential rental requirements, local traffic laws, and parking regulations for 2026.

Renting a car in Buenos Aires, Argentina, gives travelers the freedom to navigate a metropolis of approximately 2.89 million residents and venture into the wider Pampas region. While public transit serves the city center well, a personal vehicle is highly beneficial for day trips and regional travel. Navigating the local rental market requires understanding specific documentation rules, age limits, and the unique traffic regulations of the City of Buenos Aires (CABA) compared to the surrounding Buenos Aires Province. This guide provides a factual overview of the essential requirements, parking rules, toll costs, and driving habits you need to know for a smooth rental experience in 2026.

L'essentiel: Key Rules, Age Limits, and Parking

To secure a car hire in Buenos Aires, Argentina, you must present a physical passport, a valid driver's license in the Latin alphabet (or accompanied by an International Driving Permit), and a physical credit card in the main driver's name for the security deposit. While the legal driving age in Argentina is 18, most rental agencies require drivers to be at least 21 or 25. Renters under 25 typically face a young driver surcharge of $25 to $50 per day.

Parking in the City of Buenos Aires (CABA) follows simplified rules implemented in April 2023: parking is permitted on both sides of conventional streets 24/7. On avenues, it is allowed on both sides from 9:00 PM to 7:00 AM on business days (and 24 hours on weekends and holidays). Parking is strictly prohibited 24/7 on passages, Metrobus streets, shared streets, and next to bike lanes. You can verify parking rules for any address by messaging the city's official WhatsApp chatbot, 'Boti', at (+54 9) 11-5050-0147. Note that metered parking zones are actively enforced in central areas.

Rental Costs, Surcharges, and Highway Tolls

When budgeting to rent a car in Buenos Aires, Argentina, factor in potential young driver fees ($25 to $50 daily) and highway tolls. Many motorways surrounding the capital require electronic toll payments via the 'TelePASE' system. Major rental agencies provide TelePASE-equipped vehicles for an additional fee, though keeping cash as a backup is recommended.

For 2026, official toll rates for cars (per plaza) include:

• Autopista Panamericana: ARS 1,800–2,400
• Acceso Oeste: ARS 1,600–2,200
• Autopista Buenos Aires–La Plata: ARS 1,400–2,000
• Buenos Aires Urban highways (AUSA): ARS 800–1,400

Speed limits are strictly enforced: 40 km/h on urban streets, 60 km/h on avenues, 110 km/h on rural roads, and 120-130 km/h on motorways. In school zones and underpasses, the limit drops to 20 km/h.

Where to Pick Up Your Rental Car

Car rental services are widely available at the two primary airports serving Buenos Aires. Ministro Pistarini International Airport (Ezeiza - EZE) handles most international flights, while Jorge Newbery Airfield (Aeroparque - AEP), located closer to the city center, handles domestic and regional routes. Major rental agencies, including Hertz, Avis, and Localiza, operate counters directly inside the terminals at both airports. Booking in advance is highly recommended to secure your preferred vehicle class and ensure the availability of TelePASE devices for highway travel.

Driving Tips and Regional Travel

Driving in and around Buenos Aires requires attention to specific national and local laws. Under Argentine traffic law, headlights must remain switched on at all times, even during broad daylight. Additionally, making a left turn on main avenues is prohibited unless explicitly permitted by traffic signs.

Alcohol limits vary significantly by jurisdiction. The City of Buenos Aires (CABA) maintains a Blood Alcohol Concentration (BAC) limit of 0.05% for general drivers. However, if you cross into the surrounding Province of Buenos Aires, a strict national zero-tolerance law (0.00% BAC) applies. This zero-tolerance limit is active on all national roads and across 18 provinces, making it safest to avoid alcohol entirely when driving.
