The state is still committed to shutting down Warren County’s Driver Testing Center, something that will happen before May 31 if local officials are not successful in either reaching an agreement with the state or derailing the consolidation plan in the General Assembly.“We have saved Tennessee taxpayers $1.3 million as a result of these mergers,” said Bill Gibbons, Commissioner of Safety and Homeland Security during his meeting at Warren County Administrative Offices on Tuesday afternoon. Gibbons noted Warren County's will be the ninth to close. “Not a single position has been eliminated," he said.
