LITCHFIELD, IL. (KMOX) -  The driver of a school bus involved in a scary-looking crash on I-55 near Litchfield Monday has been ticketed for failing to reduce his speed to avoid an accident.

66-year-old Henry Jaeger was at the wheel of the bus bringing sixth grade students back from Grant Fork school back from a field trip when he rear-ended a tractor-trailer.

Illinois State Police say the semi had either stopped or slowed while approaching a construction zone.

The collision occurred at 4:34 P.M.  Monday.

Illinois State Police now say the bus was carrying 33 students from Grant Fork Elementary School.

They had been on a field trip to Springfield to view the capitol and the Lincoln Museum.

Ten injured people, including the bus driver Jaeger, were originally transported to Litchfield and Hillsboro area hospitals.

Three students were been airlifted by Arch Helicopter to Cardinal Glennon Hospital in St. Louis.

The uninjured students were taken back to Grant Fork School and parents were told to take their children to a hospital to be checked.

Ambulances from at least eight departments were on the scene. Some estimates put as many as twenty ambulances on the scene at one time.

The front end of the school bus and part of the side of the bus was torn open. The rear of the semi also suffered extensive damage.

Neither of the vehicles were overturned.
