State Patrol's historical timeline: 1990-1999*


  • The Computer Aided Radio Log (CARL) developed specifically for the State Patrol in 1991 enabled dispatchers to use computerized functions to replace tasks previously completed by written communications.
  • In-car videotaping equipment was first installed in cruisers in 1992 as part of a study to access the system’s effectiveness and utility. The system cost about $1,650 per cruiser.
  • A law was enacted that provided troopers and inspectors with the full enforcement powers of a police officer for Wisconsin laws in 1993.
  • Trooper William Schoenberger died on April 22, 1993, from injuries suffered in the line of duty. (In memoriam)
  • A new emergency vehicle operator course (EVOC) opened at the academy in 1994.
  • The first mobile computers began to be installed in cruisers in 1995. By 1999, mobile data computers (MDCs) built by Panasonic were being used by troopers and inspectors to obtain critical information about motorists’ licenses and vehicle registration without having to use voice communications.
  • The Chemical Testing Section evaluated and approved the Intoximeter EC/IR for evidential breath testing results for determining alcohol levels in 1998. The Intoximeter replaced the Intoxilyzer equipment.
  • The position of State Patrol superintendent was created in 1999. Unlike the previous classification of administrator for the head of the agency, only a sworn officer could hold the position of superintendent.
  • The radio communications program for the Department of Natural Resources was consolidated with the State Patrol in 1999.
