ST. LOUIS – A Georgia trucker who lost consciousness before his tractor-trailer struck and killed an Illinois state trooper isn't medically fit to drive commercially, federal regulators have determined.

The U.S. Department of Transportation's Federal Motor Carrier Safety Administration, in an order issued last Friday, found that Johnny Felton Jr. "failed to exercise an appropriate duty of care to the motoring public" regarding his medical conditions the agency said disqualified him from trucking.

The department didn't detail Felton's conditions, which were redacted in the agency's order.
