What countries have bi, tri (or even more?!) lingual signs?

[Vierwielen]

I remember a sign at a services near London that had French , Spanish etc but also it had albanian . Never met any albanians here

Clacket Lane? English, German, French and Czech.

Quite why Czech rather than Polish I don't know.

What is the point of that sign, a clearway on a motorway. Also any European driver should know the rules of a motorway.

Years ago, there were a series of signs outside Sheerness in French, Spanish and German reminding drivers to "Keep left", but the regular ferry to Sheerness at the time was the Vlissingen ferry and most of the non-British vehicles on the road had Dutch numberplates.

Well, the Dutch usually have a better command of English than most natives. Some Germans might well come that way, but French and Spanish seem redundant in that location.
