Rota de trólebus 4 no mapa de Vilnius

One of it not the best trolleybus route in Vilnius. Unlike Antakalnis's main route, 2, it's not that overcrowded, though still has a reasonable amount of passengers. Traffic jams are prominent, though, also, not as bad as route 2. Probably the biggest issue with this route would be infrequency at particular times, especially on weekend evenings. The shortening to Gerosios Vilties st. on weekends is also quite confusing, as both route 6, and route 12, which are very, very similar (both start at Žirmūnai, then split apart, and join back together at Žaliasis tiltas for the most of the route), go to Žemieji Paneriai all the time. Why not shorten route 12 to Gerosios Vilties st., and extended route 4 while giving it more trolleybuses? Would seem pretty logical to me. Nevertheless, compared to some other trolleybus routes, it is pretty good.
