US Drivers in Argentina 2026: 0.08 at Home, Zero Here

Can Americans drive in Argentina on a US licence? Only with an International Driving Permit alongside it. The U.S. State Department puts it as needing “an Argentine or international driver’s license”, and Argentine practice treats the permit as a legal requirement, not a courtesy. AAA issues it in the US, and there is no way to get one after you land, so it belongs on the pre-departure checklist next to the passport. Traffic keeps to the right, as at home. Alcohol does not: the limit is zero.

Can you drive there from the US?

Some travellers dream of the full overland trip. The road runs out at the Darién Gap, the roadless stretch between Panama and Colombia, so a car has to be shipped around it. For almost everyone, Argentina is a fly-and-rent destination. If you do arrive in your own US-registered vehicle, the same IDP rule applies.

Paperwork at the rental desk

Put the IDP, your US licence and your passport on the counter together, and keep them together in the car. The State Department advises making sure you have adequate insurance before long road trips, so read the coverage carefully, especially for gravel roads (ripio), which some contracts treat differently. Check the Driving Permit Checker if Chile or Uruguay is also on the route.

Zero alcohol, in every province

Law 27.714, in force since May 2023, rewrote national traffic law so that driving with any alcohol in the blood is prohibited across the country. Most US states allow 0.08. That gap is the single biggest legal change for an American driver, and a glass of Malbec with a long Argentine dinner is the classic way to cross it. On driving days, have none.

Buenos Aires versus the open road

The State Department is direct: driving is more dangerous than in the United States. Drivers tend to be aggressive, especially in Buenos Aires, and often ignore traffic rules. In the capital, leave extra space, expect lane changes without signals, and consider leaving the car parked and using taxis while you are in the city. Inside towns, the limit is 40 km/h on ordinary streets and 60 km/h on avenues and through-roads, so watch for the change each time you turn off a main road.

Once you head south or west, the problem flips from traffic to distance. Gas stations are often far apart and not always easy to spot from the highway, the State Department notes. In Patagonia this matters most. Fill the tank at every opportunity, carry water and snacks, and do not rely on mobile signal between towns. Gravel sections can be hard on a normal hire car, so ask the rental company which roads its cars are allowed on.

Speed limits in mph

Fines, in pesos

Amounts vary by province, and inflation moves them often. As a guide: up to 10 km/h over costs around ARS 10,000-30,000, a bigger overstep ARS 30,000-90,000, and the most serious cases more than ARS 90,000 plus a licence suspension. A phone at the wheel runs ARS 20,000-50,000, a red light ARS 30,000-90,000, no seatbelt ARS 10,000-30,000. The speeding fine calculator gives a quick estimate.

What must be in the car

Argentine rules require a warning triangle, a reflective vest, a fire extinguisher, a first-aid kit and spare bulbs. Most Americans have never had to carry the whole set, so open the boot and check each one before leaving the lot.

Emergency numbers

911 works as the general emergency line, which is one familiar thing. Argentina also has direct numbers: police 101, ambulance 107, fire 100. The Argentina driving guide covers regional road conditions in more detail.
