DPS is the Russian traffic police, and its distinctive two-tone siren is instantly familiar to audiences in Russia and other Russian-speaking countries from everyday road traffic. Short recordings of the siren circulate widely in memes, gaming clips and short-form videos, where it is used as a shorthand for police arriving, a chase starting or someone getting caught. Because the sound needs no translation, it works in edits even for viewers who do not speak Russian, which keeps it popular for comedic busts and dramatic interruptions.
