Polish road signs typeface
Polish road signs typeface () – geometrical typeface meant to making text 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 has been created by Marek Sigmund, who made the project commissioned by the state authorities in 1975, while the Instruction about road signs and signals () was being implemented. The typeface has been designed in six weeks. According to the designer's assumptions, the typeface included creating text on boards by using the freehand and stencil techniques. This typeface has poor readability when trying to read a small text while driving at high speed. Electronic versions
