WEATHERFORD -- Walmart heiress Alice Walton faces a charge of driving under the influence in Parker County.
She was arrested Wednesday on her 62nd birthday.
A state trooper pulled her over in a construction zone in Weatherford.
Department of Public Safety said she failed a field sobriety test, but refused a breath test.
Walton is the daughter of Sam Walton. Forbes currently lists her as the tenth richest person in America.
The DUI arrest is not her first. She was arrested in Arkansas in 1998 and was convicted of DUI charges.
