“The stepped-up enforcement of highway laws came as a new CDC study showed most U.S. drivers reported talking on their cellphone and about one in three read or sent text or email messages when driving. Roberts, who usually steers a motorcycle or standard patrol car in Meigs, McMinn and Rhea counties, is one of 97 troopers statewide who hold a commercial driver’s license that allow them to use a semi truck. On Wednesday, Roberts spotted seven people breaking the laws below him. He thought he saw a Volkswagen driver texting, but he wasn’t sure; maybe she was just dialing a number.”
