driver’S licenSe

Well, add your American version
https://www.gov.uk/browse/driving/driving-licences
That said, 'international' appears to be 'permit' - https://www.gov.uk/guidance/international-driving-permits-for-uk-drivers-from-28-march-2019

It’s not American, it’s international. In the Ngram, I chose English, which includes all Englishes.

Sorry, I had added the wrong Ngram...

I hate arguing with you, but just google for either 'international driving permit' or 'international driver's permit' and then see the images.
BTW, the one that I once was given in Russia was in French

I just looked and you’re right - they also use “international driving licenCe/permit” Good job!
