What is special about speed & redlight alerts?


I am wondering what is special about the speed & redlight POI's that enable them to pop up on my Garmin 660 with a red warning bar at the top of the display. None of the other POI's such as rest areas show up automatically as do the speed & redlight files. If you can tell me what makes this happen, how can I modify other POI's to bring up an alert automatically when I am approaching the POI. Thanks; Dave in Canton, Ohio question
