Bus, Tram, Maxitaxi & Trolleybus. Romanian cities generally have good public-transportation systems comprised of buses, trams, trolleybuses and, in some cases, maxitaxis. Bucharest is the only Romanian city with an underground metro.Taxis are cheap, reliable and a useful supplement to the public-transportation systems. Drivers are required by law to post their rates on their doors or windscreens. The going rate varies from city to city but ranges from 1.39 to 1.79 lei per kilometre. Any driver posting a higher fare is likely looking to rip off unsuspecting passengers.
