Macon singer Nick Malloy apparently overcorrected his steering early Wednesday after he had nodded off, veering down an embankment and hitting a culvert and trees, authorities said Friday.

Malloy drove onto a grassy patch on the left side of the Bass Road exit off Interstate 75 North, then veered right and went down an embankment, according to an accident report. He crashed into a culvert, flipped over, hit one tree and then another.

His vehicle, a 1998 Acura CL 3.0, came to rest on all four wheels. The car traveled an estimated 336 feet from the grassy patch to the final point of impact.

Malloy, 23, lay inside his wrecked car for several hours until a passer-by spotted the wreck about 7:30 a.m. and called 911.

The son of WMAZ anchorman Frank Malloy, he was taken to The Medical Center of Central Georgia, where he has undergone surgery for multiple injuries.

According to a Bibb County accident report, Malloy was not tested for alcohol. Deputies didn’t notice the smell of alcohol when they arrived at the wreck scene. Use of a cell phone didn’t contribute to the crash, Lt. Sean DeFoe said.
