At approximately 7:20 a.m., officials were dispatched to an area north of County Road 1300 N., on State Road 59.
According to Indiana State Police Trooper Bill Bradbury, the truck, a 2004 Black Ford F150 driven by Mark W. Merrill, 22, Terre Haute, was heading north on SR 59 when he failed to yield as a Clay Community Schools (CCS) bus had its stop arm out.
The truck then struck the student, a male, who was attempting to board the bus. Officials said eyewitnesses claimed the male "flipped over the truck."
"He was responsive," Bradbury said, adding officials suspected he might have sustained injuries to both of his legs.
State Police officials later confirmed the student, identified as 15-year-old Logan Parr, had been transported to St. Vincent Clay for treatment of a possible fractured left leg and numerous abrasions and contusions.
Officials with CCS said the bus had all its lights on during the stop. All lights were functioning during an inspection conducted by Indiana State Police troopers, which was requested by CCS officials on scene.
"Anytime there is an injured person, we like to get the state police involved," CCS Transportation Director Frank Misner said.
Other students on the bus were transported to another school bus and taken from the scene.
Officials told The Brazil Times Merrill and a male passenger stated they were going hunting.
Officials said Merrill, who was not injured, was taken to the Clay County Justice Center and preliminarily charged with one count of Criminal Recklessness with a Vehicle (a Class A misdemeanor) and one count of Reckless Driving (Passing a School Bus Stop Arm and Causing Bodily Injury), also a Class A misdemeanor.
His bond was set at $5,000, with 10 percent acceptable.
The driver of the school bus, Jack Glancy, 74, was not injured, nor were any of the eight other students on the bus.
Both north and south lanes of SR 59 were opened for traffic flow at approximately 8:48 a.m.
Other agencies responding the accident included the Van Buren Township Volunteer Fire Department, Clay County Sheriff's Department and TransCare.
