The typeface was created by Marek Sigmund, who made the project commissioned by the state authorities in 1975, while the Instruction about road signs and signals (Polish: Instrukcja o znakach i sygnałach drogowych) was being implemented. The typeface was designed in six weeks. According to the designer's assumptions, the typeface included creating text on boards by using the freehand and stencil techniques.[2][3]
Sigmund's specifications included glyphs that appear cut-off or oversized (such as the flat right edge on lowercase "e" and capital "G") and a purely geometric approach to letter design; in general, Polish signage uses large letters to ensure readability.[4]
Liternictwo Drogowe – distributed by the company Centrum Rozwoju Explotrans S.A., which cooperates with Ministry of Infrastructure. It completely matches the Regulation, and is meant mainly for the enterprises that produce road signs.[5]
Tablica drogowa – created in 2001 by Grzegorz Klimczewski. This version has all the glyphs that are defined in the Regulation and also additional ones (including Q and X letters). Some unused glyphs, such as (quotation mark, question mark, percent sign), have been replaced by arrows. At first, the font was distributed commercially, but currently it is non-commercial freeware.[6]
Drogowskaz – created in 2006 by Emil Wojtacki. Apart from the glyphs defined in the Regulation, it includes many more, designed in style of the original typeface, such as scribal abbreviations and diacritics used in various languages. The font is distributed as non-commercial freeware.
W droge — created in 2011 by Open Source Publishing, a secondhand tracing of the typeface from real-world signage in Wroclaw. It is distributed under a permissive free software license.[7]
