A lorry driver who caused a fatal crash on the M25 after a 15-hour non-stop driving stint has been jailed for four and a half years.
Anton Maizen killed 79-year-old Ronald Moughton when he ploughed his 40-tonne lorry into the back of the pensioner's Renault Clio after he failed to notice queuing traffic on the London orbital.
Two other motorists are still recovering from their injuries in hospital.
The crash occurred near Aveley in Essex in April this year, after Maizen had been at work for 23 hours, and had embarked on a marathon 840-mile drive the previous day from his home country, Germany.
When interviewed by police, Maizen was unable to explain why he had not slowed for the traffic, which had hit at his maximum limited speed of 56mph.
He admitted causing death and serious injury by dangerous driving on Friday. In addition to his custodial sentence Maizen was banned from driving for five years.
