This terrifying footage shows an HGV driver ploughing into motorway traffic whilst he was on his mobile phone.
The 30-year-old man has been jailed for eight months after he caused a major crash on the M1 near Harrow .
Razvan Rusu, of no fixed abode, crashed his HGV on March 17 last year into slow moving traffic near junction 2 of the busy motorway.
The crash damaged three cars and injured two drivers who were both taken to hospital for treatment.
The shocking dash cam footage clearly shows Rusu using his mobile for two kilometres before he crashed.
Detective Sergeant Stephen Pidgeon, from the serious collision investigation unit of the Met Police, said: “Rarely is it possible to see such a clear example of the risks some drivers are willing to take with mobile phones and the danger that using them whilst driving can cause.
“It is only down to the quick thinking of one of the drivers who moved just before impact that there weren't multiple serious injuries or worse.
“That the driver was willing to take these risks whilst being aware that he was being filmed is even more incredible.”
Rusu was sentenced at Harrow Crown Court after he pleaded guilty to dangerous driving at the same court on Monday October 10.
He was banned from driving for three years and will be forced to take an extended retest.
Rusu had been living in the UK but left the country for Romania after the crash.
When he returned to the UK he was summonsed to court and his passport was seized.
