Emergency crews were on the scene of an accident involving a school bus and a car near the Wisconsin border Thursday.
It happened on Route 45 in Union Grove, Wis., just south of Highway 142 in Kenosha County.
A car appears to have crashed into the back of the bus, wedging itself underneath.
The driver of the car was pinned inside the vehicle but was eventually extricated and flown to a hospital.
It's not clear if any students were on the bus or if there were any more injuries, but there didn't appear to be heavy damage to the bus.
Authorities are investigating the cause of the crash.
