Less than 16 hours after a crash Thursday, another school bus was involved in a chain-reaction wreck involving two other vehicles, both driven by high school students.

About 8:30 a.m. Friday, a school bus was struck from behind by a sport utility vehicle that had been hit by another SUV on Pilgrim Mill Road.

According to Forsyth County Sheriff’s Deputy Courtney Spriggs, the incident is still under investigation, but the bus “was turning onto Pilgrim Point Road and a car behind it stopped to turn.”

“A third vehicle hit the vehicle behind the bus, which then hit the bus,” she said.

The drivers of both vehicles were students at Forsyth Central High School, authorities said. Their names have not been released.

Forsyth County Fire Division Chief Jason Shivers said one of the 22 students on board the school bus was treated for minor injuries and released to a parent.

The driver of one of the two SUVs involved also suffered minor injuries, he said.

According to Spriggs, the damage to the bus was “so minor that they left the children on [it] and took them to school on that bus.”

Forsyth County Schools spokeswoman Jennifer Caracciolo said the system is “grateful that the students on the bus, as well as the students in the cars, are OK.”

The bus, which she said was headed to Little Mill Middle School, was being driven by a six-year veteran of the system.
