Two young brothers were not wearing seatbelts when they died in a motorway crash on Christmas Day when their mum's car hit a tree.
An inquest heard that Mohammed Arsalaan Habib, four, and his older brother Adnan, 10, were killed alongside their aunt Bushra Tazarib, 32, while on their way to a family wedding. Their mum, Parveen Habib, 38, and her daughter, who was the front-seat passenger, escaped with minor injuries.
The inquest was told Mrs Habib sent her red Ford Focus into a spin like 'scenes from a movie' before crashing down an embankment and into a tree near Junction 15 of the M6, near Keele, Staffordshire.
Mrs Tazarib and Adnan were not wearing seatbelts at the time of the horrific collision while Arsalaan was not properly restrained in his car seat. Mrs Tazarib and Adnan may have taken them off to reach for some snacks, while Arsalaan could have wriggled out of his shoulder straps.
Mrs Habib was told in June this year she will not been charged in connection with the deaths, despite hitting speeds of 90mph in the run up to the crash.
The court heard the exact cause of the accident remains a mystery, but may have been down to a momentary loss of concentration or a faulty tyre.
Recording a narrative verdict that all three victims died in a road traffic collision, North Staffordshire coroner David James said: "The circumstances were tragic and distressing.
"I find that no other vehicles were either involved or contributed towards this incident and there is no evidence for the reason for the loss of control."
Mrs Habib was driving from her home in High Wycombe, Buckinghamshire, to a wedding in Bolton.
At the time of the crash, former world boxing champion Amir Khan, a second cousin of the bride at the wedding they were due to attend, said: "It is such a tragic incident and my deepest condolences are with the family and friends of all three who passed away.
"To lose two boys and a young woman in circumstances like these is devastating. My thoughts and prayers are with them."
