States That Use Blue Alerts — And How Each System Works

Last updated on February 28th, 2026 at 06:09 am

When a police officer has been harmed or killed while on duty, and the suspect has not been identified, a Blue Alert will be issued that helps solicit help from the general public in locating a suspect who has caused serious bodily harm or death to an officer or one who is continuing to risk the safety of law enforcement and the general public.

Blue Alerts will be transmitted through multiple means of communication, including cellular (text message) and broadcast media, including television and radio news outlets, and highway message signs.

All states have implemented a Blue Alert Program that is operated in a similar manner to all other states; below is the listing of all states with a description of the respective Blue Alert Guidelines for each state.

What Is a Blue Alert?

A Blue Alert can be issued when there is:

A police officer who has either been severely injured or killed. 

There is an individual who has no longer been in custody. 

People are at risk because of this individual.

There is sufficient information to help locate the individual.

The intent behind the Blue Alert is to quickly inform and protect the person being notified and to obtain assistance for law enforcement from the general public.

Why Blue Alerts Matter?

Blue Alerts help:

• Catch dangerous suspects faster
  
• Warn communities about serious threats
  
• Support law enforcement efforts
  
• Improve public safety
  

However, states must use these alerts carefully to avoid sending too many notifications. That is why strict rules are followed before issuing them.

Conclusion

The Blue Alert uses various methods for disseminating this information including electronic notification of media outlets, and electronically posting messages on highway display boards; thus, allowing individuals to remain informed and prepared for possible threat(s) to themselves or their loved ones.
