One person was seriously injured today in a three-vehicle collision involving a school bus on Old Whitesville Road south of Moncks Corner, authorities said.

There were four Whitesville Elementary School students on the bus, but none of them were injured, said Kathie Sizemore, a spokeswoman for the Berkeley County School District.

The children were transferred to another bus and taken home, she said. The bus and its driver remained at the scene while the S.C. Highway Patrol conducted its investigation, she said.

According to the S.C. Highway Patrol, the collision took place about 2:30 p.m.

All three of the vehicles were traveling in the same direction when the driver of a pickup truck tried to pass several vehicles at once.

The driver cut back into the traffic, between the school bus and a Ford sport-utility vehicle, said Lance Cpl. Bob Beres of the Highway Patrol. The pickup truck hit the school bus and the SUV, causing it to go off the roadway and flip over, Beres said.

The driver of the pickup, William S. Alongi, 24, is being charged with driving under the influence, Beres said. Alongi will be taken to the Hill-Finklea Detention Center upon his release from the hospital, Beres said.

According to court records, Alongi, of Moncks Corner, was out on bail, wearing a court-ordered ankle monitor.

He was charged by the Berkeley County Sheriff's Office in March with attempted murder, criminal domestic violence of a high and aggravated nature and malicious injury to property.
