A Blue Alert is a public safety alert that goes out when a law enforcement officer has been killed, seriously injured, or is in serious danger, and the suspect is on the loose and considered a credible threat to others.

What a Blue Alert Is

  • It is a specialized alert type in the U.S., similar in concept to an AMBER Alert but focused on threats involving law enforcement officers.
  • The alert is designed to rapidly share information with other police agencies, news media, and the general public to help locate a suspect and warn people about the danger.

You’ll typically see it pop up as a push notification on phones, on highway signs, TV, or radio via the Emergency Alert System.

When a Blue Alert Gets Issued

Exact rules vary by state, but the core idea is similar. Common criteria include:

  1. A law enforcement officer has:
    • Been killed,
    • Suffered serious or life‑threatening injury,
    • Been assaulted with a deadly weapon, or
    • Been abducted or gone missing in worrying circumstances while on duty.
  1. The suspect has fled the scene and is not in custody.
  1. Authorities believe the suspect poses an ongoing, credible threat to the public or other officers.
  1. There is enough descriptive info (for example, vehicle description or tag) that sharing it with the public could realistically help locate the suspect.

How Blue Alerts Reach You

  • Distributed via:
    • Wireless emergency alerts to phones.
* Emergency Alert System (TV and radio).

* Highway and roadside message signs.
  • The national Blue Alert Network helps states coordinate these systems across the country.

So if your phone suddenly flashes a Blue Alert, it usually means authorities are urgently looking for someone who has attacked or seriously threatened an officer and might still be dangerous in your area.
