Driver flees on foot after hit-run in Vic

A driver is on the run following a hit-run crash on a Melbourne freeway.

Police say a Holden was travelling at 155 km/h in a 60 km/h zone on the Princes Freeway, Laverton, about 7.20am when it hit a vehicle but failed to stop.

It sparked a police chase, but the driver continued speeding and crashed into a fence after exiting the freeway.

The driver then fled on foot.

Police are hunting the driver, who was the sole occupant, and want anyone with dash cam footage to contact them.
