5. Black cab. The famous London taxis are actually called 'hackney carriages' but in London we just call them 'black cabs/taxis'. London taxi drivers have to pass a special exam called the Knowledge to get their license so if you take a black cab, you can be sure the driver will know the way.
Yellow cab taxicab operators exist all around the world (some with common heritage, some without). The original Yellow Cab Company, based in Chicago, Illinois, was one of the largest taxicab companies in the United States.
A symbol of London and Britain, the black taxi is a common sight on the streets of the UK. The hackney carriages carry a roof sign TAXI that can be illuminated at night to indicate their availability for passengers.
Farelady, a modified London taxi is touted as the world's most luxurious taxi and at 120,000 pounds (approx ?1.21 crore) may be one of the most expensive taxis. The Farelady gets a revamped and more imposing grille which is inspired by the grille on some of the Mercedes-Maybach models.
If you see that the light is on (you'll know if it is, it's a bright yellow light), then to hail the cab simply stand on the side of the pavement and extend your arm outward. There's no need to shout “taxi” and indeed, it's actually illegal to shout “taxi” whilst trying to hail a cab.
