Douglas County law enforcement officers faced a close call during a traffic stop early Friday.

Deputies and Douglasville police officers were arresting a driver on traffic charges when another driver crashed into a parked patrol car, according to the Douglas County Sheriff’s Office. The crash happened on the Chapel Hill entrance ramp to Interstate 20 in Douglas County.

The crash was bad enough to deploy the air bags and knocked the patrol car into the rear of a deputy’s car, deputies said. Though no one was inside the cars, the crash impact caused a deputy standing nearby to fall, authorities said.

“He sustained minor injuries minor lacerations to his right arm, and he complained of injury to his right knee,” Georgia State Patrol Cpl. Michael Stewart said.

Stewart said the crash is a perfect example of why the Move-Over-Law was designed. He said drivers need to give officers room to do their work.

“Yield that lane to them if you can. If at all possible, move over to the next lane possible leave them all the room you can there,” Stewart said.

The driver involved in the crash told authorities she had been drinking, according to the GSP. Channel 2 Action News was there as she underwent a field sobriety test. The GSP is investigating whether to charge her with driving under the influence.
