More than a dozen were injured and a driver was charged with driving under the influence after a tour bus traveling to the Masters Tournament in Georgia overturned on a highway.

At least 15 people were being treated at local hospitals from injuries sustained in the crash on Interstate-20 in Columbia County, according to WRDW-TV. Eighteen people were on the bus at the time. Several passengers were reportedly suffering non-life threatening injuries.    

Steven F. Hoppenbrouwer, 61, was charged with a DUI and failure to maintain lane, according to the station. Police said they believed Hoppenbrouwer had been using drugs, not alcohol.

Georgia State Patrol told Fox News the driver ran the bus off the side of the road and overcorrected to the left before it overturned on the median. The bus was about 20 miles from Augusta National Golf Club.

The accident snarled traffic for nearly two hours.

Sgt. Chris Wright of the Georgia State Patrol told The Associated Press one passenger told troopers he had decided before the crash: "I'm not riding back with him. I'll call an Uber."
