Trapster was a navigation social networking mobile application and website, provided for free, that maps out and alerts users in real time to the presence of live police speed traps, DUI checkpoints, traffic, red light cameras, speed cameras, and areas where police often hide.
[7] Trapster can use Wi-Fi or GPS to pinpoint the user's current location[8] and send them audio alerts or text messages when they are approaching a ticket threat.
Users can customize the alerts via the Trapster website or the mobile app so that they only receive notifications of conditions they are interested in, such as red light cameras or live police.
[13] Bill Johnson, executive director of the National Association of Police Organizations stated that he is all for it if the result is that people slow down.
Brent Barbee of the Amarillo, Texas Police Department said "Having (motorists) slow down on their own is a lot less manpower-intensive than having us forced to spend time writing tickets.
[18] When checked on December 21, 2014, it was discovered the Trapster website was put into closure mode, thereby cutting off new activations, and the Twitter account permanently closed.
