A man has been arrested on suspicion of causing death by dangerous driving and failing to stop at the scene of an accident after a fatal motorway crash.
A 53-year-old victim was killed when he was thrown from a pick-up truck after it was hit by a van on the M6 at around 5.50am on Saturday.
The crash happened in the northbound carriageway between junction 35 at Carnforth and Burton-in-Kendal Services.
It is believed the collision occurred when the white Transit-type van drove into the back of the car transporter.
Lancashire Police said the impact rolled the transporter, while the van failed to stop and was driven off.
A police spokesman confirmed a 46-year-old man from Warwickshire was arrested shortly afterwards and questioned in custody by officers.
He has since been released on police bail pending further enquiries.
Firefighters were called to the scene to free the driver’s wife who was trapped in the passenger seat in the car transporter, while two ambulances and two rapid response cars were also despatched to the incident.
The woman was taken to Royal Lancaster Hospital where she was treated for injuries, which were not thought to be life-threatening.
The M6 was closed between junctions 34 and 36 until the late afternoon while investigations were carried out.
The Highways Agency put diversions in place but there were traffic delays of around 30 minutes until the motorway was partially reopened.
Police, who confirmed the couple were from Huddersfield, West Yorkshire, are now appealing for witnesses following the crash.
Chief Inspector Tim Leeson said: “We are currently trying to establish the circumstances surrounding the collision and we would appeal to anyone with any information to come forward.
“I would appeal to anyone who may have been travelling along the M6 around that time that may have witnessed anything to contact us if they have not already done so by calling 101 and quoting log number 0479.”
