A "devoted mother" who died in a car crash had strapped her two children in but was not wearing a seatbelt herself, an inquest heard.
Laura Kinrade, 27, from Jurby, died and her two young children, who were in the back seats, survived when the car hit a tree on the Isle of Man in 2016.
She crashed on a 50mph zone of the A3 Lezayre Road but it was "difficult" to know her speed, the inquest was told.
Coroner John Needham recorded a verdict of accidental death.
Ms Kinrade's children were treated for "minor injuries" at Noble's Hospital after the crash on 30 October, the hearing at Douglas courthouse was told.
She was travelling home from Ramsey towards the west of the island with her children and the family dog when she lost control.
The car crashed into a tree before "whipping violently around, throwing Laura backwards through the rear window", Mr Needham said.
A post-mortem examination found she died from head injuries.
Police said Ms Kinrade was not wearing a seatbelt.
Mr Needham said: "Laura was a much-loved family member and devoted mother - it is tragic she should die in this way.
"I am not in a position to say why she lost control of the car - this was not a low-speed collision but it is difficult to know what speed she was travelling at."
The dog was seen walking away from the crash by a witness, the inquest was told.
Police tests showed the road, which had been resurfaced the day before, had a "slightly lower than expected level of grip".
The inquest concluded this would have not been a significant factor in the crash.
