If you would like to explore Argentina , travelling by car is a good way to do so. With your own vehicle, you are independent and able to visit attractions which are often hard to reach with public transportation. 

Most of the roads in Argentina are in good condition. But there are also gravel and dirt roads – especially off the main roads and in the south of the country - for which an 4x4 vehicle is highly recommended. This is particularly true during or after the rainy season. For this reason, you should take a good road map with you e.g. Argentina Road Map by World Mapping Project. But it is even more important to be well informed about the situation on the route you are going to drive: For detailed information about road conditions, the estimate travel time and further facts on more than 120 routes use the service of cochera andina. On the website of Argentina's national traffic system you will find up-to-date info about traffic congestions, construction sites etc.

In general the traffic rules in Argentina are the same as in the U.S. ore Europe , however their interpretation by the locals is different – drive attentively. Pay attention at night: road users and streets often have little or no lights at all. 

A driver's license of your country is sufficient. However, in order to avoid any complications it is recommended to take an international driver’s license with you.

Speed limits: 60 km/h in the city and 100 km/h to 120 km/h outside the city as well as on the highways. Don’t drive faster than the speed limit, there are many strict speed checks.

Petrol is reasonably priced in Argentina (approx. 3,50 $ per gallon / 0,90 $ per liter), see current petrol prices In the Andes, the petrol consumption often increases to over 15 litres per 100 km. Although the gas station system is rather dense keep in mind to fill your tank regularly and take a reserve canister with you.

The best is renting a car directly in Patagonia, Iguazu or Atacama but not in Buenos Aires. From Buenos Aires the distances are to big, it is better flying. The roads that connect Buenos Aires to the other big cities can be dangerous. In Patagonia or Atacama there is almost no traffic.
