Up until 1991, the total number of cars in Albania was between 5000 and 7000. In 1991, the Albanian government lifted the decades-old ban on private-vehicle ownership. As a result, car imports numbered about 1,500 per month. Traffic in the capital remained light, but traffic lights and other control devices were urgently needed to deal with the multiplying number of privately owned cars. Albanian entrepreneurs also imported used Greek buses and started carrying passengers on intercity routes that did not exist or had been poorly serviced during the communist era.
