Problem Oriented Public Safety

The State Patrol’s style of community policing is called Problem Oriented Public Safety, or POPS. The foundation of POPS is based on a philosophy of taking the concerns of the motoring public by addressing persistent problems. When a problem is identified by a citizen, trooper, or anyone with a concern, the POPS trooper works with other agencies and groups to develop the best achievable solution to address the origin of the problem. Solutions to various problems may range from simply educating the public to major construction projects.
