An Atlants father was arrested amid claims he passed out from a drink and drugs binge while driving his toddler son.

Police accused Robert Eugene Mobley of losing consciousness while driving his SUV with his two-year-old son sat in the front passenger seat.

He was arrested after police reportedly discovered him in the car at a motorway slip road in Atlanta, at 5.30am on Sunday August 10.

Police said it took three attempts to wake the 39-year-old as he lay slumped over the steering wheel with his foot on the brake. The car's engine was believed to be still running.

A bottle and cup containing whiskey were found inside the vehicle.

While being questioned by police, Mobley allegedly gave a false name, calling himself Robert Griffin.

He was arrested on several charges including driving under the influence, cocaine possession and child endangerment.
