Traffic jam

This isn't your run-of-the-mill traffic jam. It was caused by a trolley car whose electrical cable had become unhooked. Usually this isn't a major problem, since the driver just leaps out, grabs a long pole from the rear of the trolley, and tries to hook the cable back on to the overhead street wires. For some reason, it appeared that the trolley's cable couldn't reach the overhead wires. Serbian drivers are not patient, and leaned on their horns. A motorcycle policeman came along with another one to direct traffic. Then a rescue truck. Finally a small bulldozer came to lift one end of the trolley just a bit so the cable could be rehooked. This whole adventure lasted "only" twenty minutes, but in the meantime, automobile drivers were having fits, and even the bus you see in the photo grew impatient.
