AMBER & Blue Alerts

AMBER Alerts

AMBER stands for America's Missing: Broadcast Emergency Response and it is a U.S. Department of Justice program used to respond to the abduction of a child. AMBER alerts must be declared by an on-duty LEO Supervisor or LEO Command Member, before messages can be displayed on our CMS boards. AMBER Alert messages are typically a three-line message that provides information to motorists on the abduction of a child. The message should display a vehicle description and license plate number (or partial number).

The following guidelines must be strictly followed when creating an AMBER Alert display, as to allow for the best readability and uniformity across the state.


  • AMBER Alerts can be displayed on any and all signs across the state, which are otherwise not in use.

  • Row A should ONLY include the text 'CHLD ABDUCTION'.

  • Row B should include a vehicle description, including the color, make & model if possible. They should also follow that exact order in the row.

  • Row C should include the state of the vehicles registration & the license plate. (For example: SA 12ABC345)
