"The officer was alert and conscious and is being treated at this time," the statement read.
The driver of the vehicle that struck the officer remained on scene and traffic charges are pending.
In Georgia, there is a "Move Over Law," which says "motorists travelling in the lane adjacent to the shoulder must move-over one lane when emergency and utility vehicles are stopped on the side of the highway and operating in an official capacity."
