Tracey Houghton, 45, and her sons Ethan, 13, and Joshua, 11, as well as her partner’s daughter, Aimee Goldsmith, 11, were travelling back from a holiday when tragedy struck on the A34 near Newbury in Berkshire.
Lorry driver Tomasz Kroker was approaching from behind when he decided to change the music on his phone.
He failed to notice the traffic in front of him and ploughed directly into the family’s car – killing them instantly.
Dashcam footage of the tragic incident in 2015 has been re-released as part of a desperate plea from family and police for drivers never be tempted to use the car at the wheel.
The footage – which was posted by Surrey Police – features heartbreaking interviews with relatives of the tragic family.
Doug Houghton – the dad of Ethan and Joshua – said: “I thought that was the worst day of my life, my kids being killed.
“But I think it was three weeks later when I went to the funeral director’s and actually saw them, dead, cold, in their coffins.”
Aimee’s dad, Mark, said the children “couldn’t wait to get home” to play Pokemon and had kissed and hugged him before getting into the car.
Her tearful mum Kate recalled the moment police knocked on her door and told her her daughter had been killed.
“I continue to see drivers using their phones and it sickens me,” she said.
“If they had seen the devastation they brought my family, or to other families, by using phones, illegally… distracting themselves from driving a potential weapon.
“Would they be as sickened as we are?”
Kroker, 30, was jailed for 10 years at Reading Crown Court after pleading guilty to four deaths by dangerous driving and a single count of causing serious injury by dangerous driving.
