The driver of the Ford Focus was released from the hospital Tuesday night with injuries less severe than initially anticipated, according to Denton police spokesman Bryan Cose.
He said traffic investigators suspect the driver may have fallen asleep at the wheel before the crash. There hasn't yet been any indication that drugs or alcohol played a role, he said.
No charges have been filed.
A man was taken to Medical City Denton with unknown injuries Tuesday after driving a Ford Fusion head-on into a school bus carrying the Lake Dallas Middle School football team, according to Denton police.
Denton police spokesman Bryan Cose identified the driver of the Ford as a 22-year-old Denton man. He said the crash occurred at about 5:30 p.m. on U.S. Highway 380 near North Mayhill Road.
Cose did not know the driver's condition as of Tuesday evening.
He said the Ford crossed over the center lanes of traffic before striking the bus.
Cose said one student on the bus complained of neck pain after the crash, and his parents have been notified. He said all other students appeared to be OK.
The preliminary investigation showed that the bus was traveling eastbound and the Ford westbound, Cose said.
