A driver had a lucky escape after an object hurled from an overpass smashed his window last night.
The object, believed to be a rock, was hurled from The Avenue overpass at Figtree at about 8pm.
The driver, a 35-year-old male from the western Sydney suburb of Raby, was uninjured.
The truck only suffered minor damage and was able to be driven away.
The driver did not see anyone on the overpass before the incident.
Police investigations are continuing.
