Swiss drivers license valid once left
Hi - I have a Swiss drivers license and ive now left Switzerland since 2006. Im a British national and have been living in Asia since. I'm popping back next month and intend to hire a car, but realised it may not be valid as its linked to my old Swiss visa.
I'm assuming it's no longer valid, but does anyone know for sure? It has no expiry date, blank, just issue date and visa number.
Many thanks in advance
