Illegal taxicab operation 非法营运车辆

Illegal taxicabs, sometimes known as gypsy cabs, are taxicabs and other for-hire vehicles that are not duly licensed or permitted by the jurisdiction in which they operate. Most major cities of the United States and worldwide require taxicabs to be licensed, safety-inspected, insured as for-hire vehicles and use taxi meters and there may also be requirements that the taxi driver be registered or accredited. However, many unlicensed cabs are in operation. Illegal cabs may be marked taxi vehicles (sometimes referred to as "speedy cabs"), and others are personal vehicles used by an individual to offer unauthorized taxi-like services. Illegal cabs are prevalent in cities with medallion systems, which restrict the number of legal cabs in operation. Since their introduction in 2009, Uber taxis, which are crowd-sourced smartphone-enabled unlicensed taxis, have been classified as illegal taxicabs in some jurisdictions.
