The Bureau of Field Operations (BFO) provides traffic law enforcement services and promotes highway safety in Wisconsin. This is primarily accomplished by troopers, inspectors, and law enforcement dispatchers located in Wisconsin State Patrol Posts and Safety and Weight Enforcement Facilities statewide. The Motor Carrier Enforcement section oversees motor carrier safety and weight facilities (SWEFs), and inspects and regulates motor carriers, school buses and ambulances. The bureau also enforces criminal and traffic laws, conducts criminal highway interdiction programs, and helps local law enforcement agencies with traffic safety, civil disturbances and disasters (natural and man-made).
