In which direction does this bus go?
'Direzione' — 'di-re-TSYO-ne'. Four syllables; stress on the third. The 'z' is like 'ts' in 'pizza'.
Use when multiple buses share the same stop and you need to confirm you are boarding the one heading in the right direction.
'In quale direzione' means 'in which direction'. 'Va' is the third-person singular present of 'andare'. This is particularly important at stops served by the same route in both directions.
Va verso il nord o verso il sud?
Does it go north or south?
Uses cardinal directions as reference.
Questo va verso la stazione?
Does this one go towards the station?
Uses a landmark as directional reference.
È quello giusto per andare a...?
Is this the right one to go to...?
Checks both direction and destination simultaneously.
Italian bus stops on opposite sides of the road often serve the same route number in opposite directions. The destination displayed on the front ('capolinea') is the most reliable indicator of direction.
