Authorities said a 79-year-old driver of a Cadillac SUV is at fault for an accident around noon involving a logging truck on Mike Padgett Highway.
The driver of the Cadillac was traveling south on Mike Padgett when he turned left onto Horseshoe Road in front of the oncoming Freightliner, authorities said. He was transported to Medical College of Georgia Hospital in serious condition, police said.
The driver of the logging truck was not injured.
Another vehicle overturned at Willis Foreman and Windsor Spring roads and trapped one person inside, authorities said.
Richmond County Sheriff's Capt. Gay said the driver, identified as Kimberly Williams, is believed to have been drinking when her Ford Taurus sped around a curve and flipped in the 2600 block of Willis Foreman Road. She was trapped inside, although not seriously injured.
Williams was charged with failure to maintain lane, driving under the influence and open container, according to police.
