Road sign gantry with variable-message signs on the A 3 in Frankfurt am Main

Traffic signs, installations, and symbols used in Germany are prescribed by the Road Traffic Regulation (StVO) (German: Straßenverkehrs-Ordnung) and the Traffic Signs Catalog (VzKat) (German: Verkehrszeichenkatalog).[1][2]

§§ 39 to 43 of the StVO regulate the effect of traffic signs and installations. Annexes 1 to 3 illustrate most danger, regulatory, and directional signs and annex 4 illustrates the traffic installations. Other traffic signs and installations not specified in the StVO, primarily specific supplementary signs, are published in the VzKat.[1]

The VzKat was issued in May 2017[2] under the General Administrative Rules for the Road Traffic Regulation (VwV-StVO) (German: Allgemeine Verwaltungsvorschrift zur Straßenverkehrs-Ordnung).[3]

The StVO, the VwV-StVO and the VzKat are supported by technical rules (German: Technische Regelwerke), mostly published by the Forschungsgesellschaft für Straßen- und Verkehrswesen (FGSV), especially:

All signs have assigned numbers. The suffix number after the hyphen refers to the variation of the sign; the suffix on signs with variable numbers is the number depicted on the sign (for speed limits, maximum heights, etc.).[2]
