I've made a few trips to various European countries in the last couple of years. I learned about the need to have a Crit'Air sticker for French cities -- all set. But now I'm seeing indications that driving in European cities might require multiple registrations, to avoid fines.
That need becomes apparent via reading about the experience of foreign motorists in the UK: link.
So, it seems that any trip planning now has an added dimension. Sometimes it works out that no registration is needed. But the only way to know is to do the research, in detail. (Example: since I'm going to Ghent soon, I've discovered that registration for the Flemish region is needed. If I later go to the French part of Belgium? Perhaps another registration...)
Here is where you can find the details (though not easily): Home
