Renting a car in Foz do Iguaçu: can you cross the border?
Marco Três newsroom · edited by Annie Grellmann
Green Card insurance, rental authorization and traffic rules in Argentina and Paraguay
Renting a car in Foz to go to Argentina or Paraguay requires the rental company's authorization and the Green Card. Not all allow it; confirm before booking.
Direct answer: You can cross the border with a rental car from Foz do Iguaçu, but only if the rental company authorizes it and issues the Green Card (Mercosur's mandatory insurance). Most do not allow it by default, so confirm BEFORE booking, not on pickup day.
What you need
- Green Card (Carta Verde): mandatory third-party liability insurance to drive in Argentina and Paraguay. Many companies do not provide it.
- Written authorization from the rental company to take the car abroad. Without it you can be turned back at the border.
- Car documents, your driver's license and travel ID.
Before you book
Ask in writing: (1) can the car go to Argentina and Paraguay? (2) is the Green Card included? Some hand over the car ready to cross; others do not allow it at all.
Traffic rules
- Argentina: headlights always on, even by day, and seatbelts for everyone.
- Paraguay: heavier traffic, watch for motorcycles.
