Chapter 96 of the Public Acts of 1919 created the Tennessee State Police which was renamed the Tennessee Highway patrol in 1929 and was administered by the Department of Finance and Taxation until 1937 when the Highway Patrol was transferred to the Department of Administration. In 1939 the Department of Safety was created as its own entity and its duties were transferred from the Department of Administration. In 1945 the Department received cabinet-level status and currently oversees the Highway patrol, handgun laws, driver's license issuance, and the Office of Homeland Security.
