Federal Highway Police
The Brazilian Federal Highway Police (Portuguese: Polícia Rodoviária Federal, PRF) is a federal highway patrol, subordinate to the Ministry of Justice and Public Security, whose main function is fighting crime on Brazilian federal roads and highways, as well as monitoring and supervising vehicular traffic, although it has also taken on duties that go beyond its original authority, such as action within Brazilian cities and forests in conjunction with other public safety agencies. It was subordinate to the old National Department of Roadways (Departamento Nacional de Estradas de Rodagem or DNER), now the National Department of Transport Infrastructure (Departamento Nacional de Infra-Estrutura de Transportes or DNIT), until the publication of Law 8,028 of 12 April 1990, which redefined the structure of the Brazilian executive branch.
