What does Signal 86 indicate in law enforcement communications?

Signal 86 is specifically used in law enforcement communications to indicate a "Drug Courier Alert." This signal helps officers communicate quickly and effectively about suspicious activities related to drug trafficking. When this signal is used, law enforcement personnel are alerted to be vigilant for individuals or vehicles potentially involved in drug smuggling or distribution activities.

Understanding the implications of this signal is important for ensuring public safety and facilitating coordinated responses to potential drug-related offenses. The other options, while significant in their contexts, pertain to different situations within law enforcement that require unique responses and codes.
