Some major roads in Argentina are maintained by private companies, others by local governments, and the conditions of these roads vary considerably. Many national roads have only one lane in each direction whereas you get two or three lanes on the motorways. Local driving styles can be erratic to say the least, so do be aware of this when driving your car rental! Many areas are lacking in direction signs, so at times it may be necessary to pull over and ask locals for help. In towns, at junctions without traffic lights or signs, a car approaching from your right has right of way. Make sure you research the many road regulations in Argentina thoroughly before you pick up your car hire.
