No other vehicles were involved and Scott County Emergency Management Agency director Jack Donovan told the Lexington Herald-Leader the truck driver wasn't hurt.
The road was closed while the flammable load was retrieved and the truck uprighted.
Donovan said the tanker was leaking in two places, but it wasn't clear how much of the 7,000-gallon cargo spilled.
