 A man involved in last week’s horror collision on the Princes Freeway has died in hospital.

Police believe a truck was travelling towards Melbourne when it collided with a sedan at about 11.55am last Tuesday.

The driver of the car, a 78-year-old Pakenham man, was rushed to hospital with life-threatening injuries.

Tragically, he passed away on Monday.

Following the crash, the truck rolled onto the wire rope barrier and stopped on the centre median strip – causing up to six hours of traffic delays.

Police interviewed the driver of the truck, a 35-year-old man from Ferntree Gully, but he was released pending further enquiries.

Major Collision Investigation Unit detectives continue to investigate the incident.

Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
