A traffic police officer needed hospital treatment after he was thrown to the ground following a high-speed collision.

Dashcam footage released by the Oklahoma Highway Patrol showed Jesse Gregory talking to the driver of a car he had stopped when a black SUV smashed into the passenger’s side.

Launched into side of Interstate 40 

Mr Gregory can be seen launched into the grassy area to the side of Interstate 40 near Oklahoma City but is heard making a radio call at the end of the video.

The officer and two others were left needing medical treatment but have since left hospital after sustaining no major injuries.

Oklahoma Highway Patrol say the crash that occurred during a routine traffic stop remains under investigation as they look into the cause of the collision.
