An SUV slammed "head on" into a school bus Wednesday afternoon on rain-slicked roads in Merrifield, but no serious injuries are reported, Fairfax County Police say.

Police received a call about the crash at 4:23 p.m. Wednesday. The bus and students were coming from Shrevewood Elementary School, FCPS Spokesman John Torre told Patch.

The crash — which occurred near the intersection of Gallows Road and Park Tower Drive,  about two blocks south of the Dunn Loring Metro Station  — closed down southbound Gallows Road during rush hour, Fairfax County Police spokesman Don Gotthardt said.

Students were being taken off of the damaged school bus and boarding a second school bus, believed to be a Fairfax County Public Schools bus, according to Gotthardt.

No students were injured but the driver of the SUV had a "minor injury," Gotthardt said.
