A 37-year-old Chestertown man working on a water line on Ft. Smallwood Road in Baltimore was seriously injured when a tractor trailer crashed into his parked pickup truck and pushed it on top of him Monday afternoon, Anne Arundel County police said.

The victim, John Scott Ford, was taken to the University of Maryland Shock Trauma in serious but stable condition after the crash around 12:15 p.m.

The driver of the Baystate Pools tractor trailer, Christopher Clark Rabel, 42, of Baltimore, didn't see the arrow board latched to the back of Ford's Chevrolet pickup, police said. The pickup was parked 10 feet from where Ford was working, on southbound Ft. Smallwood Road near Kembo Road, police said.

Police said the investigation is continuing but the crash appeared to be due to driver inattentiveness on Rabel's part, and speed did not appear to be a factor.
