A school bus and a Peterbilt collided on Route 444 in Kent County. There were no serious injuries, but state police say one student complained of an arm injury after getting to school. The bus hit the rear of the tractor trailer, which was stopped on the roadside. Troopers say the driver of the tractor-trailer was cited for not properly putting warning devices in the roadway. There was no major damage to either the truck or the bus. Students got a letter from the school to take home to parents.
