The Minnesota State Patrol is the statewide police force in the state of Minnesota. While the State Patrol concentrates primarily on traffic enforcement and highway safety it also has a statewide law enforcement role. Troopers are also involved with accident reconstruction and commercial vehicle enforcement. The State Patrol capitol security division also handles the security for the Minnesota State Capitol grounds and the governor. Additionally, the State Patrol maintains a K-9 unit that focuses on drug enforcement interdiction, as well as a Special Response Team (SRT), that operates like a traditional SWAT Team.
