"Carta Verde" is a mandatory insurance for international trips with vehicles registered in Mercosur countries, excluding the country where the car is rented. Essential to protect third parties in case of traffic accidents during the rental period, this insurance must be acquired directly from the rental company.

Make sure to verify the issuance of the "Carta Verde," along with all associated fees and costs, with the rental company responsible for the vehicle at least 3 days before pickup. It's worth noting that the "Carta Verde" insurance does not replace the need for a specific authorization to cross borders. Failure to present the "Carta Verde" when requested by the country's authorities may result in fines.
