Most of the cities and tourist areas have car rentals; depending on the company you may be able to return the car in another city. Although renting a car offers the tourist flexibility when traveling, one should take into account that car rental in Argentina tends to be costly. In Argentina you are allowed to use your regular drivers license, although it is highly recommended to get an international drivers license or international translation of driving licence. In order to drive in the country a person must be older than 18 years of age.

While driving in Argentina it is advisable not to exceed the speed limit and to obey all transit signs. Although bribing is common, if you receive a traffic ticket from a police officer, it is better not to argue and just accept the fine. Wearing a seat belt is a must, although generally people do not use them. It is prohibited to make left hand turns on main roads unless there is a left turn arrow at a stoplight indicating you to do so. In cities the maximum velocity is 40 k/h (25 mph) and 60 k/h (almost 40 mph) on main roads. On rapid highways the maximum speed permitted is 120 k/h (75 mph), while on main roads the maximum reaches up to 80 k/h (50 mph). Driving in a city like Buenos Aires can be rather chaotic, due to the quantity of vehicles and the narrowness of some streets. Drivers are typically aggressive, the streets are a mess, and there is little or no respect for pedestrians. You should drive defensively and with great care.

From  Argentina you can travel by car to neighboring countries. There are highways leading to Chile, Bolivia, Paraguay and the border with Brazil. Each country has border controls where you will be asked for your passport and visa (in case you need it to enter the country) and all valid automobile documents. The continuing rural roads are not in good condition nor are they well marked with signs.
It is also worth mentioning that the expressways are privately owned, therefore you have to pay a toll from one stretch of road to another . Although there are plenty of gas stations in every city and on highways, it is wise to fill your gas tank before setting out on rural roads since gas stations are harder to find in isolated areas. In Argentina gas is called nafta.
