Order at the junction: L, E, N, R

The right order is L, E, N, R. The trolleybus R does not have right of way and goes last.

N waits for E, E waits for L, R waits for E and N.

Word: Filobus = an electric bus with overhead wires.

The exam is in Italian: key terms and trap words are kept in Italian, so you learn them.
