Meters are technically required by Egyptian law, but they generally go unused and in many cases do not even work. The prime exception is in Cairo, where a new class of taxis with a different livery (white with a black checkered band around the middle) have electronic meters installed and used. In most other cases, the price of a journey is generally determined through negotiation or bargaining between the passenger and driver, either just after the cab is hailed or just after the destination is reached.
