All taxis in Buenos Aires city are black and have yellow tops. An unoccupied one will have a small, red libre" sign on the lefthand side of its windshield. When hailing a taxi on the street make sure it says radio taxi" and that you see a CB antenna attached to the hood. Radio taxis are part of licensed fleets and are in constant contact with dispatchers; nonlicensed cabs are occasionally driven by unscrupulous men looking to rip off tourists; avoid them. If you telephone for a taxi, you'll have to wait a few minutes, but you can be sure of its origin and safety. Legally, all taxis are supposed to have working seatbelts, but this isn't always the case.
