Video evidence played in court has been released showing the lead-up to the deaths of four Victorian police officers who were struck by a semi-trailer driven by a drug-impaired truckie.
Mohinder Singh, 48, was sentenced to 22 years' jail in Victoria's Supreme Court on Wednesday following the fatal crash in April last year.
The new video released by the court shows Singh's truck at times failing to remain inside his lane's markings along Melbourne's Eastern Freeway.
One clip shows him driving in the middle of two lanes as he passes a slip lane while another sees a motorist head into the breakdown lane to avoid a potential collision with the wandering truck.
Moments later, Singh struck the officers who had pulled over Porsche driver Richard Pusey for speeding at the Kew section of the highway.
Constable Lynette Taylor, Senior Constable Kevin King, and constables Glen Humphris and Josh Prestney died at the scene.
Truck driver high on drugs, court hears
Singh was short on sleep and high on drugs at the time of the crash, the court heard.
He will be eligible for parole after serving 18 years and six months in jail.
Justice Paul Coghlan said the crash had "shocked the public conscience".
He described footage of the incident as "chilling" and said the officers stood no hope of survival.
"The grief of those close to the victims is profound and life-changing," Justice Coghlan told the court.
"Such grief is heightened by the sudden and unnecessary nature of the deaths. We can only hope ... as time goes by, some amelioration of their suffering can come about."
'No punishment can replace the loss'
Const Prestney's father read out a statement on behalf of the families of the four officers outside court.
Flanked by his wife Belinda and son Alex, Andrew Prestney thanked the first responders and members of the public at the scene for the "care and respect that was shown to our loved ones".
"We share a history with them now and forever," Mr Prestney said.
"Even though justice has now been served in relation to the actual collision, no amount of punishment can replace the loss of our loved ones and the missing place at our tables that will be felt by us for the rest of our lives."
Pusey, who filmed the officers on his phone as they died, will be sentenced later this month after pleading guilty to outraging public decency, speeding and reckless conduct.
Pusey avoided being struck by Singh's truck as he was urinating at the side of the road at the time.
