The European Union is moving towards compulsory introduction of a procedure under which a driver may be traced from a scrap of paint left behind by a car at the scene of a crime or a hit-and-run accident. The EU Council of justice and home affairs ministers has called on the European Commission to produce a directive that would compel registration documents to carry an adjective and alphanumeric code specifying the colour of the vehicle, saying this was necessary to combat "the development of organised crime" and to "better protect public and private interests in police and/or judicial inquiries."
