PC Mark Goodlad killed in M1 crash while helping driver
Tributes have been paid to a policeman who was killed in a collision involving a lorry on the M1 near Wakefield.
PC Mark Goodlad, 41, was hit on Monday afternoon after helping a woman whose car had broken down on the hard shoulder of the southbound carriageway.
The lorry driver, a 44-year-old Oldham man, has been arrested on suspicion of causing death by dangerous driving.
West Yorkshire's chief constable Sir Norman Bettison said the officer had "paid the ultimate sacrifice".
Police said that at the time of the collision PC Goodlad was standing between his marked BMW X5 and the woman's Suzuki Swift.
Sir Norman said: "People sometimes overlook the real essence of policing. We exist to protect the public from threat and harm.
"Sometimes it is about crime, sometimes disorder. Today, it was about the dangerous environment of the motorway.
"PC Mark Goodlad was assisting a vulnerable motorist, who had broken down in that dangerous space. He was doing his job as his colleagues do day-in day-out.
"Police officers put themselves at risk for others. Mark paid the ultimate sacrifice and we are all proud of him and are saddened by his loss.
"Our thoughts and sympathy are with Mark's family. We shall try to be there for them as Mark was there for the public at large."
PC Goodlad, from Goole in East Yorkshire, was in a marked police car when the accident happened at 16:15 BST between junctions 40 and 39.
He was later airlifted to hospital, where he died.
The 51-year-old woman who he stopped to help suffered minor injuries.
West Yorkshire Police Federation chairman Andrew Tempest-Mitchell said it was a "sad day" for the force to lose such a "dedicated officer".
"It was my understanding he was a very experienced road traffic officer," he said.
Yvette Cooper, shadow home secretary and a West Yorkshire MP, said the news of his death was "desperately painful and sad".
"All our sympathies and thoughts go out to his family and friends," she said. "This loss is felt by the whole community and police force in West Yorkshire.
"PC Goodlad and so many police officers across the country put their lives at risk every night so we all can be safer and more secure, and they deserve our deepest thanks and gratitude at all times."
Tributes to PC Goodlad were posted on Twitter. One tweet said: "How sad, no-one should die doing their job."
