WASHINGTON COUNTY, Md. -- A new dashcam video illustrates how dangerous highways can become when drivers fail to obey a law known as the "move over" law.
Oklahoma does have a "move over" law.
Maryland State Police released the dashcam vid of a traffic accident that seriously injured an officer during a routine traffic stop in June.
The trooper was hit by a tractor trailer driving too close to the shoulder.
The semi smashed into his patrol car.
A "move over" law requires drivers to literally move over or slow down when they see first responders along the side of the roadway.
The officer is recovering from the accident with several serious injuries.
