Your Buenos Aires Adventure Starts at EZE Airport

You'll need both your US license AND an International Driving Permit (IDP). Argentine law requires foreign drivers to carry an IDP (available from AAA in the US for ~$20) along with their original license. Without an IDP, rental companies will likely refuse to hand over the vehicle, and local police can fine you on the spot. The IDP is valid for 1 year and translates your license into Spanish.

Yes. Most rental agencies in Argentina charge a 'young driver' fee for drivers under 25, typically ranging from $10-$25 USD per day on top of the base rate. This adds up quickly—a 7-day rental could cost you an extra $70-$175. Budget accordingly and compare quotes across agencies, as surcharges vary widely. Some agencies (like Localiza) have lower age minimums at 21, while others require 25 for certain vehicle classes.

Argentina's toll roads (peajes) accept cash and sometimes credit cards at the booth. Major highways like Autopista Panamericana and RN9 have staffed tolls where you pay 200-500 ARS (~$0.50-$1.50 USD) depending on vehicle class. Not all lanes accept cards, so always carry 1,000-2,000 ARS in cash as backup. Electronic toll collection (TEP) exists but isn't universally available—don't rely on renting an e-tag unless explicitly offered by your agency.

Downtown BA has both street parking (with meters accepting coins or the 'Pase Cultural' app) and underground garages. Street parking costs ~30-60 ARS/hour (~$0.10-$0.20 USD) in busy areas like Microcentro, but spot availability is poor during business hours. Overnight street parking isn't recommended due to break-in risks—use a garage for ~$15-$25 USD/night. Look for 'estacionamiento' signs and always keep your receipt on the dashboard.

BA traffic is aggressive by US standards. Drivers frequently ignore lane markings, run yellow lights, and use horns aggressively (it's communication, not rudeness). One key difference: right turns on red are prohibited unless explicitly posted. Also, 'Vuelta de回过头' (U-turns) at intersections are common but can be tricky. Download offline maps (Google Maps works offline) since GPS signal can be patchy in some neighborhoods. If you're renting a car mainly to explore BA itself, consider skipping it—Uber/Subway is faster and cheaper for city driving.

Credit card coverage typically does NOT apply in Argentina due to country exclusions in most premium cards (Chase Sapphire, Amex Gold, etc. often exclude Argentina). Plan on purchasing the rental agency's Collision Damage Waiver (CDW) with a deductible—expect to pay $20-$35 USD/day for comprehensive coverage. Verify with your credit card issuer BEFORE you book. Also, note that uninsured/underinsured motorist rates are lower in Argentina, so personal liability coverage of at least $50,000 USD is strongly recommended.
