Traffic light coalition (direct translation of German: Ampelkoalition) is a term originating in German politics where it describes a coalition government of the Social Democratic Party of Germany (SPD), the Free Democratic Party (FDP), and The Greens. It arises from the fact that the parties' traditional colours, respectively red, yellow, and green, resemble the normal colour sequence of a traffic light (Ampel). It has subsequently been used to describe similar coalitions between social democrats, liberals, and greens in other countries.
