The New York City Taxi and Limousine Commission (TLC), created in 1971, is the agency responsible for licensing and regulating New York City's medallion (yellow) taxicabs, for-hire vehicles (community-based liveries and black cars), commuter vans, paratransit vehicles (ambulettes) and certain luxury limousines. The TLC licenses and regulates over 50,000 vehicles and approximately 100,000 drivers, and performs safety and emissions inspections of the 13,637 medallion taxicabs three times each year, as well as biennial inspections of all TLC-licensed For-Hire vehicles, making it the most active taxi and limousine licensing regulatory agency in the United States.
