No one was injured Wednesday afternoon when a dump truck rolled into a school bus loaded with children in Readfield, police said.

Sgt. Frank Hatch, of the Kennebec County Sheriff’s Office, said 17 students were on board the bus and no one was hurt in the low-speed crash. The impact caused only minor damage to both vehicles, he said.

Trooper Bernard Campbell, of the Maine State Police Commercial Vehicles Unit, which assisted with the investigation, charged the dump truck driver, Teague Adams, 34, of Auburn, with violations related to several brake problems on the dump truck, Hatch said. Police put the truck out of service until the brakes can be repaired.

The 17 students on the bus ranged in age from 12 to 18. Readfield students are served by Maranacook Area Schools, which is Regional School Unit 38.

The crash occurred around 2:50 p.m. as Adams turned his dump truck from Main Street onto South Road. Teague told police he “missed a gear” while shifting, which caused the truck to roll backward into the front of the school bus. The bus, dropping the students off for the day, had followed the dump truck from Main Street onto South Road.

The bus driver, Brenda Ridley, 56, of Oakland, told police she saw the truck rolling backward and tried to reverse the bus to avoid the collision, but “the truck still rolled into the bus,” Hatch said.
