The motorist in the striking vehicle has been charged with DUI.
A Maryland State Trooper assigned to the Frederick Barrack was injured early Saturday morning.
Authorities say Trooper First Class David Zanoni was sitting in his patrol car in the area of Rock Raven Road and Buck Lantz Road when a Chevrolet Equinox swerved off the roadway and hit the state police cruiser. TFC Zanoni had parked the car in the northbound shoulder while responding to a call for service. State Police say his injuries are not considered life-threatening.
Troopers arriving at the scene determined that the driver of the Equinox, identified as Robert John Gery, 19, of Smithsburg, showed signs of impairment, and field sobriety tests were conducted.
Gery has been charged with driving under the influence of alcohol, and negligent driving. He was released to the custody of his parents.
"The actions of drunk and drugged drivers continue to cause property damage, personal injury and death to innocent persons," says Lt. Mike Brady, Commander of the Frederick Barrack, in a statement. "The citizens of Maryland should be thankful that TFC Zanoni was not seriously injured by Mr. Gery, a 19-year-old who chose to put himself and others in danger.
