I frequently receive threats about my car potentially being impounded, which can be more of a hassle than an actual occurrence. While I can't guarantee they won't impound it, I've only experienced it once when my car was towed for parking in a disputed spot.
For various trips, including crossing the border to Paraguay, I've used my Texas driver's license without any issues. I've encountered routine checkpoints and even received a speeding ticket once, all with no comments on my license.
I understand that getting an Argentine driver's license is a requirement, and I acknowledge that I should do it. However, I find the process, known as "tramite," quite tedious and avoid it when possible.
Notably, I bought my car nearly three years before obtaining residency. During that time, I traveled across the border with Paraguay using my passport, insurance papers, license, and the "cedula verde" (the car's registration document) without any problems.
However, an incident occurred when I presented my temporary residency papers at the border. The law didn't allow me to cross with my car unless I had a DNI, as the precaria (temporary residency) wasn't considered sufficient. This situation happened in Clorinda, and I had to spend several stressful hours figuring out a solution. Eventually, a helpful immigration officer suggested a nearby ferry, and with some pleading, I managed to cross.
This experience prompted me to expedite the process of obtaining my DNI upon my return.
