This is the horrific moment a lorry driver ploughed into a line of rush-hour traffic leaving a man with broken bones and a fractured skull.
Vygantas Stanulis smashed into the back of a Ford Fiesta at 50mph after taking his eyes off the road.
The car was then pushed forwards, slamming into the back of a lorry laden with wooden pallets.
Harrowing footage shows the Fiesta's bonnet crumple and the windscreen fly out.
The driver of the Fiesta, a man in his 20s, was left with multiple injuries including a fractured skull, two fractured vertebrae and a fractured ankle.
Witnesses to the crash on the A2, near Canterbury, in January, said the lorry did not slow down as it approached the line of traffic.
Stanulis from Lithuania only attempted to brake about half a second before smashing into the Fiesta.
The 55-year-old had previously denied the charge but pleaded guilty on the first day of his trial.
He was later jailed for a year.
Kent Police Constable Celia Weller said Stanulis had shown remorse for the crash.
She said: "Stanulis told us he had taken his eyes off the road for a second to look at two lorries parked in a layby.
"He described it as a momentary lapse in concentration.
"He didn’t set out that morning to cause harm and is still coming to terms with what happened.
"The victim still faces operations on his face and knee and will live with the consequences of this collision for a long time."
