Blue Alerts can be transmitted to television and radio stations; to cellphones and wireless devices, to overhead highway message signs, and other secondary alerting mechanisms – in the same way that AMBER Alerts are commonly issued.
There are currently 37 states with Blue Alert plans. The COPS Office provides resources and technical assistance to states, territories, law enforcement agencies, and tribes seeking to establish or enhance Blue Alert plans; including, voluntary activation guidelines, examples of legislation, policies, and forms gathered from around the nation in a central Blue Alert data repository.
