As I'm heading to the French Alps shortly for another cycling trip (leaving the house in a few hours!
), I revisited the page on
priorité à droite, and on reading it more closely than before, realised that roundabouts in France are divided into 2 types: those in which vehicles entering the roundabout give way to those in the roundabout (a typical USA or Australian system), and those in which the reverse applies!
I remember the latter type, but don't recall seeing the former type (indicated by the arrows in a circle inside a triangle sign), but now I'll watch for it to see if I can spot any while over there.
Here's the page link again:
