A forty-year-old man was arrested late last week and charged with DUI after he was stopped for weaving in and out of his lane of traffic.  Summerville Police say that Ryan David Gifford of a Mahan Road, Summerville address, was stopped on Highway 48 after an officer noticed him not maintaining a single lane of traffic.  Police say that Gifford admitted that he had “huffed a can of air” prior to driving.  Gifford was arrested and booked into the Chattooga County Jail on charges of DUI for drugs, specifically “toxic vapor”.
