A police officer was in critical condition Sunday after he was hit by a car as he was laying flares on a highway, authorities said.
The 57-year-old driver stopped at the scene and faces a charge of aggravated assault with a motor vehicle, police said.
The name of the officer who is a two-year veteran of the department has not been released. He was taken to Methodist Dallas Medical Center where he remained in critical condition.
The incident began about 5:45 a.m. when officers responded to a possible hit-and-run with a disturbance in the westbound lane of Interstate 20 at Mountain Creek Parkway.
At the scene, officers decided to shut down the far right lane of I-20.
One officer began laying flares in the far right lane of I-20 when a witness told police a Toyota Venza approached the accident scene, drove around a squad car which had its emergency lights on and onto the emergency shoulder of the far right lane.
When he re-entered the roadway, the motorist hit the officer who was standing in the far right lane.
Police said the injured officer was improving.
Police identified the driver as Boniface Madubuko who was in the Dallas County Jail Monday in lieu of $100,000 bail.
