GorkFart kontrol
This is either Norwegian or Danish.
It’s true that ‘fart’ means speed in Swedish, but in this context ‘hastighet’ would be used (~‘hastiness’).
Probably Denmark then. European route E47 goes from Germany to Sweden, E55 from Greece to Sweden. In Denmark they share the same physical road for a while.
These signs are not Danish, not officially at least. “Fartkontrol” is a Danish word but the sign is not an official sign and in Denmark we wouldn’t split “fart” and “kontrol” into separate words.
The first one is Danish. It is split up like that because of the width of the sign, and it is an official sign. The second one isn’t Danish.
