This is the horrifying moment a 'selfish, arrogant' lorry driver causes a fatal crash while distracted by pornography on his mobile phone.

Neil Platt, 43, ploughed into queuing traffic on the M58 in Lancashire, tragically killing father-of-two Danny Aitchison instantly.

Today Platt - branded a 'a multi-tonne accident waiting to happen' - was jailed for ten years after he pleaded guilty to causing death by dangerous driving.

He told police he hadn't touched his mobile phone - but damning in-cab footage from his HGV showed him repeatedly pressing the screen.

As he neared the end of his journey from Dumfries in Scotland to Liverpool on May 17 last year, Platt was looking at photographs of naked women on X - formerly Twitter - while driving at 54mph.
