New York City taxis are most commonly called "Yellow Cabs" or simply "Cabs." Officially, they are known as Medallion Taxis because they are the only vehicles authorized to pick up passengers via street hails anywhere in the five boroughs. The "Medallion" refers to the physical plate attached to the hood of the car that serves as its license. In addition to the iconic yellow cabs, NYC also has Green Taxis (officially called Street Hail Liveries or SHLs). These were introduced to serve the "outer boroughs" (The Bronx, Brooklyn, Queens, and Staten Island) and Upper Manhattan; they can be hailed on the street in those areas but are prohibited from picking up hails in the "Yellow Zone" of Manhattan's central business district. In 2026, these taxis are increasingly integrated with the Curb and Arro apps, allowing users to hail them digitally just like an Uber. Despite the rise of ridesharing, the "Yellow Cab" remains the ultimate symbol of New York City transit, instantly recognizable by its vibrant paint and illuminated rooftop "off-duty" signs.
