A man from Halifax has been killed in a freak accident.
Mark Pearson, from Pye Nest Gardens, died after a piece of metal smashed through his windscreen and hit him while he was driving along a motorway.
The 41-year-old was driving a silver Vauxhall Vectra on the M6 on the northbound carriageway and was just approaching the exit at junction 31 at Preston when the accident happened at 11am on Wednesday.
It is thought the metal may have come off another vehicle.
Lancashire Police said an ambulance was called and he was taken to hospital but he died shortly after arriving there.
Mr Pearson is understood to have a wife and a seven-year-old daughter.
Sergeant Dave Hogarth, from the Lancashire Road Policing Unit, said: “This appears to be an incredibly tragic incident where in the most unusual of circumstances, a man has sadly lost his life.
“I would appeal to anyone who was on the motorway that morning and who witnessed what happened to come forward and contact the police.
“I also want motorists to check their vehicles and loads to see if they are missing anything.
“It is important that we carry out a thorough investigation so we can establish exactly what has happened.
“Clearly this is an incredibly difficult time for the family of the man and we have specially trained family liaison officers supporting them.”
The northbound carriageway of the M6 was shut for several hours to allow accident investigators to carryout a full examination of the scene.
Anyone with information is asked to call Lancashire police on 101.
