[1] The German blazon reads: Ein rot-silberner geschachteter Schild, belegt mit einem grünen Wellenbalken.

The municipality's arms might in English heraldic language be described thus: Chequy of twenty gules and argent a fess wavy vert.

Since there is not much of a clue about the village's local history, the municipality adopted the arms formerly borne by the “Hinder” County of Sponheim, but with the addition of a wavy fess (horizontal stripe).

The former county's “chequy” arms of course recall the village's allegiance thereto in centuries gone by, and the fess is canting for the second syllable in Daubach's name, Bach being the German word for “brook”.

[11] Running by 8 km south of Daubach are Bundesstraße 41 and the Nahe Valley Railway (Bingen–Saarbrücken), on which is a station at Bad Sobernheim.
