We rent cars frequently when in Europe and elsewhere and have never needed an international driving permit. Just prior to our most recent roadtrip from Belgium, I came across information that really changes things. We’re in Antwerp house- and cat-sitting for a couple of months again and had some days away to do something with while the owners were home between their travels. I booked a rent car awhile back, but hadn’t settled on where we should go. We’d been thinking northern France and the Channel Islands, but were starting to lean more towards Switzerland since David had never been. A “why not” run to Lichtenstein had also piqued my interest so I began plotting out a drive south through France to Switzerland, factoring in a stop in Dinant, Belgium, that had been on my want-to-see list for some years.
