The collision happened just after 7:30 at the intersection of 2nd Street S. and S. Jackson Street, a busy route for students walking to and from school.
The boy suffered serious but non-life-threatening injuries and was transported to Inova Fairfax Hospital, according to Arlington County Fire Department spokeswoman Lt. Sarah Marchegiani.
It was not immediately clear how the crash happened nor whether the teen was in the crosswalk when he was struck.
