Police investigations are continuing into a fatal crash in the state's North-West on Thursday evening in which a 10-year-old girl died.
The crash involved a head-on collision between a white Subaru and a white Toyota Hilux utility on the Bass Highway, about 3.5km west of Somerset, about 5.35pm.
Investigations into the incident continue today, with preliminary investigations indicating the utility crossed to the opposite lane of the highway.
The girl, from Tasmania's North-West, was a passenger in the Subaru.
The driver of that vehicle was a 65-year-old woman who is a family member. The woman received serious injuries and was transferred to the Royal Hobart Hospital on Thursday night, where she remains in a serious condition.
A male driver and his female passenger in the Hilux sustained injuries which were not believed to be life-threatening. The two people, aged in their early 20s, were transported to North West Regional Hospital and remained there overnight.
Anyone who witnessed the crash, or has relevant dash cam footage, is asked to contact Police on 131 444.
Our thoughts continue to be with families and loved ones of those involved.
