For nine decades, the Missouri State Highway Patrol has answered the call to serve and protect the citizens of this state. Yesterday was the 90th Anniversary of the start of the Missouri State Highway Patrol. In recognition of the anniversary, Governor Mike Parson proclaimed it to be Missouri State Highway Patrol Day in Missouri. In 1931, Governor Caulfield signed into law an act of the 56th Missouri General Assembly establishing the Patrol. Present day, the Patrol consists of over 1,500 Troopers and 1,200 civilian employees. Thirty-one Troopers have been killed on duty since 1931 with one member dying in World War II. Colonel Eric T. Olson, superintendent of the Missouri State Highway Patrol, says they are committed to being professional, courteous, compassionate, resourceful, and responsible.
