A man was sentenced to eight months in prison after pleading guilty to dangerous driving.

Razvan Rusu, 30, was sentenced at Harrow Crown Court on October 10, and banned from driving for three years and required to take an extended retest.

Rusu, a Romanian national left the country and returned to Romania after the incident.

On his return to the UK he was summonsed and his passport seized.

Rusu was caught on using his phone behind the wheel of a HGV lorry, on the dashboard camera.

The footage clearly showed Rusu using his mobile phone for a distance of two kilometres.

Police officers were called to the M1 near junction 2 at 8.20am on March 12.

Officers established that an HGV tipper lorry had crashed into slow moving traffic, causing damage to three cars and injuring two drivers.

Both drivers were taken to hospital for treatment but released the same day.

Detective Sergeant Stephen Pidgeon of the Serious Collision Investigation Unit 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 even worse.

"That the driver was willing to take these risks whilst being aware that he was being filmed is even more incredible."
