Fatal crash footage of a lorry piling into traffic on the M53 has been released.
Peter Tootle, 61, of Naomi Close, Blacon , was at the wheel of the truck which smashed into a queue on September 30, 2014.
Mark Done, 51, from Kirkby, was killed and 10 other people were injured as their cars were shunted together.
In agreement with the families affected, police have issued the video as a stark warning to motorists.
Merseyside Police’s Road Policing Unit Constable Darran Doyle said: “The families of those most affected by this terrible tragedy have agreed for this footage to be released to show the devastating impact of this collision.
“All of this could have been avoided if the driver had paid attention to the warning signs which were put in place on the motorway following the earlier accident and were clear to be seen."
Tootle was jailed for 30 months for causing death by dangerous driving and 25 months for causing serious injury while driving dangerously.
Pictures from the HGV's cab shows it career into the back of a Citreon HGV on the inside southbound lane.
Traffic was at a standstill on the because of an earlier collision near junction 4.
On impact the lorry causes a pile-up as the cars in front are smashed together.
Mr Done was killed while his wife Diane , who was in the passenger seat, is still undergoing treatment for her injuries.
His daughter paid tribute Sophie said the 51-year-old was the 'ultimate family man'.
Paul Johnson, 61, from Wallasey, has also been left needing 24-hour care as a result of the injuries he suffered.
PC Doyle said: “Mr Done’s family have been left without a dad and granddad and Mr Johnson’s family have been left to pick up the pieces and cope with Mr Johnson’s life-changing injuries.
“The driver of the lorry, Peter Tootle, and his family have also had their lives changed forever by what happened on that day.
“This just shows that not paying attention when behind the wheel of any vehicle can have tragic consequences.”
