Driving in Argentina on a US Licence — Mandatory IDP, a 0.05 Limit & Empty Patagonian Roads
United States
Argentina
Unlike many countries that merely suggest one, Argentina legally requires Americans to carry an International Driving Permit with their US licence. You drive on the right as at home, but the alcohol limit is a stricter 0.05 (zero in some provinces), and Patagonia's cheap fuel sits behind long, empty stretches where the next station can be 200 km away.
Americans driving in Argentina face EUR 30-90 fines for 20+ km/h over the limit, a 0.05 BAC limit (stricter than the US 0.08), and a legally mandatory IDP issued by AAA in around 10 days.
The good news for American drivers is that Argentina drives on the right, just like home, so there’s no side switch to relearn. The thing that actually catches people out is paperwork: Argentina is one of the countries where an International Driving Permit is genuinely required by law, not simply recommended at the rental desk. AAA issues one in about ten days, so apply before you leave — there is no way to obtain it once you arrive, and a hire company can refuse the car without it. Verify what your trip needs with the driving permit checker.
The second adjustment is alcohol. You may be used to the US 0.08 limit; Argentina’s national figure is 0.05, and several provinces — Córdoba among them — enforce a flat 0.00. Because the rule changes as you cross provincial borders, the only consistent policy is not to drink before driving at all.
Where Argentina really differs from a US road trip is scale and emptiness. Buenos Aires traffic is intense and fast, but the moment you head south the picture inverts: Patagonia is some of the loneliest tarmac you’ll ever drive, where petrol stations can be 200 km apart and a stretch of ripio (gravel) can punish a normal hire car. Fuel is strikingly cheap — around €0.88 a litre — but the rule is to fill up whenever you pass a YPF station, not when the gauge tells you to. Carry water, and don’t count on mobile signal between towns. The Argentina driving guide covers the regional fuel and road-condition detail.
On speed, motorways allow up to 130 km/h, rural roads 110 and city streets a low 40. Enforcement is real and a 20-plus km/h overstep typically costs the equivalent of €30 to €90, varying by province; the speeding fine calculator gives a quick estimate. The car must carry a warning triangle, reflective vest and fire extinguisher, and the all-services emergency number is 911 — familiar from home, which is one less thing to memorise. Keep your IDP, US licence and passport together at all times.

Frequently Asked Questions
Yes, but you must carry an International Driving Permit alongside your US licence and passport — Argentine law requires it, and rental firms will ask. Get the IDP from AAA before you travel; it cannot be issued in Argentina. Your licence is valid for the length of your tourist stay.
The drink-drive limit is 0.05 BAC nationally and 0.00 in some provinces such as Córdoba, both stricter than the US 0.08. Treat it as zero, especially outside Buenos Aires where limits vary by province.
Motorways run to 130 km/h and city streets to 40 km/h, but the real hazard is distance — in Patagonia, fuel stations can be 200 km apart, so fill up whenever you can rather than when you must.
