criticizing their build quality and contract signed under suspicious circumstances (allegations of corruption). Little over 400 of these buses are supposed to enter service within 2019. In July 2020, the first Mercedes-Benz Citaro Hybrid buses entered service, displacing several of the Otokar buses on other lines; the new Citaro C2 buses have similar specifications to the models ordered in several other Western European cities. On 20 January 2022, the employees of the STB staged a strike, demanding the resignation of chairman Adrian Criț. This act was condemned by the Mayor of Bucharest, who said that the strike had political undertones, and the following day, the Bucharest Courthouse declared the strike illegal. Liveries and logos The current livery was adopted in 1996 and has been in use since then. It is overall white and on trams, it has a yellow stripe applied below the headlights. The oldest livery that can be traced goes back to the 1940s when a golden ochre was used on trams. In the 1950s, with the formation of the ITB, the livery adopted was of cream for the lower (underside) and upper (from the windows to the roof) parts, whilst the rest was of a dark-red paint. For trolleybuses, the dark-red paint was only used for the underside and for a small stripe under the window. On buses, the part below the windows was full dark-red and the one above them was just cream. Alternatively, on trolleybuses, some TV20E models were painted with a lighter-blue instead of dark-red.

At this time, the blue livery began to be painted onto some of the newer trolleybuses. In 1986, the livery would be changed once again, to feature a unified design that featured a thick cream stripe in the middle and an overall red body (this was reversed on trams), after a row of experimental liveries between 1985 and 1987. However, by 1990, not all vehicles were painted. The first RATB livery was applied in 1991, it was supposed to be a transitional livery until a better design would be found. Most older vehicles were painted in
