POLICE say a 17-year-old girl was behind the wheel of the mini bus involved in a serious crash near Hay on Friday.
Seven children and a baby were hospitalised as a result.
The white Toyota Hiace was travelling east on the Sturt Highway about 12.30pm when it allegedly crossed to wrong side of the road and collided with a B-Double 15km west of the town.

An Ambulance NSW spokeswoman told The Daily Advertiser on Friday that the teenager was trapped in the vehicle for about two hours.
She was treated for a suspected fracture to her leg.

The others were taken to Westmead Hospital, where they all remain in a stable condition except for the baby, who is in a serious but stable condition.
Police from the Deniliquin Local Area Command are investigating the crash.
The 47-year-old male driver of the B-Double was not injured.
Investigations are continuing.
