Police have released footage of a fatal car crash in a warning to drivers texting behind the wheel.
The harrowing video shows the moment a lorry driver ploughed into a line of stationary vehicles as he checked his mobile phone.
Tomasz Kroker was jailed for 10 years for causing the deaths of Tracy Houghton, 45; sons Ethan, 13, and Joshua, 11; and her partner’s daughter Aimee Goldsmith, also 11.
Dash-cam footage showed Kroker scrolling through music at the wheel before causing an eight-vehicle pile up.
In the video, Aimee's mum, Kate Goldsmith, said it "sickens" her to see drivers continuing to use their phones.
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?"
