The Finnish traffic sign typeface contains a lot of errors and problems. I ended up asking about the typeface used for upcoming renewed signs from Liikennevirasto, and the conversation in Twitter lead to a CC0 release of the original typeface drawn in 1960's.
Tie is a typeface conversion of the original Finnish traffic sign typeface that is available at Liikennevirasto page.
