The Brazilian Federal Highway Police (Polícia Rodoviária Federal or PRF) is a federal highway patrol, subordinate to the Ministry of Justice, 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. Its competences are defined by article 144 of the Federal Constitution and by Law 9,503 (Brazilian Traffic Code), by Decree 1655 of 3 October 1995 and by its internal regulation, approved by Ministerial Decree 1,375 of 2 August 2007. The title patrolman given to the members was abolished in 1998, replaced by the title policewoman/-man. Members of the PRF are divided into four classes: Third, Second, First and Special. Since 2009, entry into the PRF has required a university education degree recognized by the Ministry of Education. Condition now described in Law 9,654. Organization The Federal Highway Police was created in 1928 during the administration of President Washington Luís, under the name Roadway Police (Polícia das Estradas). It is present in all units of the federation and is managed by the Federal Highway Police Department (PRF), headquartered in Brasília. The states are divided into administrative units known as regions. A region can be a "superintendency", in the case of larger states, or a "district" in smaller states. Some regions encompass more than one Brazilian state. Regions are divided into "delegations", which coordinate the patrol posts. Currently the PRF has over four hundred patrol posts in the most diverse Brazilian municipalities, providing a capillarity to the structure of the agency that few national institutions possess. Despite the uniformed work, the PRF is not a military institution and a rigid hierarchy among the police officers does not exist. The entire hierarchy is based on the functions of supervision, which can be occupied by any police officer, for example a special agent may be supervisor of an inspector. The PRF, like other law enforcement agencies, also possesses specialized centers, such as the
