The design of road signs in Poland is regulated by Regulation of the Ministers of Infrastructure and Interior Affairs and Administration on road signs and signals. The Annex 1 to the regulation describes conditions related to usage of the road signs – size, visibility, colors and light reflections, typeface and text, criteria of choosing the type of foil to signs faces, colorful specimens and schematics.
Road signs are divided by two categories – "vertical" and "horizontal". The "vertical" signs are placed on the side of the road or over the road. The "horizontal" are simply road markings painted on the carriageway, usually with white paint. The yellow paint is used on temporary situations, mostly during the road works. It has higher priority than white paint.
The road signs in Poland follow the Vienna Convention on Road Signs and Signals and, therefore, are more or less identical to those in other European countries. Warning signs have yellow background rather than the more common black-on-white design, and therefore similar to the road signs in Greece.
Polish road signs depict people with stylized silhouettes.
