Official trailers include marked police cruisers in Vice City and chase sequences. Lights, livery, and pursuit framing are visible. Rockstar has not posted a GTA 6 police-vehicle roster, radio codes, or wanted-level rules.
This page does not guess Vapid / Buffalo / Stanier identities from body lines. Community matching is a separate hobby. Map-6 only records that a police-cruiser type appears in official video.
Trailers also imply a living law-enforcement presence — cruisers in traffic, not a single prop car. That still is not a count of precincts, helicopter units, or water patrol, which belong on their own sourced rows if Rockstar shows them as named types.
Use the interactive map to pin districts where trailer chases appear to take place. Do not treat a paused frame as a confirmed spawn or a leak of dispatch AI.
