Police officers investigating the crash on the M1 near Sheffield on Sunday night also want to hear from motorists with dash cam footage of the incident or the car involved before it ran out of control.
A white Volkswagen Golf was travelling on the northbound stretch of the motorway near Woodhall – between Junction 30 for Barlborough and 31 for Aston – when the driver is believed to have lost control.
The car left the carriageway and hit a barrier and a number of trees before overturning and coming to rest on its roof.
