Drogowskaz

The Polish road signs typeface (Polish: Polskie liternictwo znaków drogowych) is a geometrical typeface designed for use on Polish road signs, according to Attachment 1 of Regulation on detailed technical conditions for road signs and signals as well as road safety devices and conditions for their placement on roads. The regulation defines a construction of digits, all of the letters of Polish alphabet and the letter V (not including Q and X), and the punctuation marks: hyphen, round brackets, comma, full stop (period) and exclamation mark. The typeface was created by Marek Sigmund, whose project, commissioned by the state authorities in 1975, was to replace the former road signage typeface 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.

Sans-serif faces work well for headings, captions, children's books and modern nonfiction. For long-form body text in print, most designers still prefer a serif.
