In Maryland, Montgomery County has seen a rash of incidents where pedestrians have been hit by vehicles.
Overnight, a woman was killed after being struck twice on Interstate 270 in Gaithersburg. The victim was first hit by a car, and then by an out-of-service Metrobus on the southbound side of the road near Route 124.
That accident comes after two incidents Monday. A 14-year-old boy was struck by a Gaithersburg police cruiser at the intersection of Darnestown and Quince Orchard Roads. The boy suffered minor injuries. Police say he was in the median but outside of the crosswalk when he was hit. And a mother and her three-year-old son, who was in a stroller, were struck on Sligo Creek Parkway at University Boulevard West.
Both suffered serious injuries but are expected to recover. Last week, a 16-month-old girl in a stroller was struck by a car in Aspen Hill.
