The two-tone siren heard here is the standard warning sound for police vehicles across much of Europe, including the Netherlands, where it is known as a politie sirene, and Germany, where the horn is called a Martinshorn. Unlike the longer wailing sirens common in the United States, the European version alternates quickly between two pitches to cut through city traffic. Clips of the sound circulate widely on soundboards and in short videos, where creators reuse the few-second loop for chases, arrests, roleplay games and jokes about getting into trouble.
