HAGERSTOWN, Maryland (NBC News Channel) -- A new dashcam video illustrates how dangerous highways can become when motorists fail to obey a law know as "the move over law."
Maryland State Police released dashcam video of a traffic accident that seriously injured trooper David Avila during a routine traffic stop along Interstate 70 in June. Trooper Avila was struck by a tractor trailer driving to close to the shoulder that slammed into his patrol car.
The new law requires drivers to literally move over or slow down when they see first responders along the side of the road.
Trooper Avila is recovering from the accident with several serious injuries. But doctors say they aren't sure Avila will be able to move his right arm again or return to work.
