"An Ordinance for the Regulation of Hackney-Coachmen in London and the places adjacent" was approved by Parliament in 1654, to remedy what it described as the "many Inconveniences do daily arise by reason of the late increase and great irregularity of Hackney Coaches and Hackney Coachmen in London, Westminster and the places thereabouts". The first hackney-carriage licences date from a 1662 Act of Parliament establishing the Commissioners of Scotland Yard to regulate them. Licences applied literally to horse-drawn carriages, later modernised as hansom cabs (1834), that operated as vehicles for hire. The 1662 act limited the licences to 400; when it expired in 1679, extra licences were created until a 1694 act imposed a limit of 700, which was increased by later acts and abolished in 1832.
