25-year-old Timothy Clement and 57-year-old David Clement were riding their bikes on the shoulder of a road, when a state trooper reportedly veered his cruiser into the breakdown lane, striking the bikers from behind.
The crash happened Thursday morning.
The conditions of both bikers are unknown at this time.
The state police sergeant was uninjured: he was escorting modular jail cells on the back of a truck headed for a local prison at the time.
The accident remains under investigation.
