"[Bollea leaving solitary confinement was] the result of routine and ongoing assessments of inmate population and classification; and the opportunity to house those juveniles who have been sentenced as adults to county time," the sheriff's office said in a statement, The Times reported.
Bollea -- the son of wrestler Terry "Hulk Hogan" Bollea -- was driving his father's 1998 Toyota Supra last August when he lost control and hit a raised median, spinning the vehicle and causing its rear end to strike a palm tree.
Bollea's front-seat passenger -- former U.S. Marine John Graziano -- spent several weeks in critical condition in a medically-induced coma and is expected to require lifelong care.
Following a more than two month investigation by police, Bollea was arrested on charges of reckless driving involving serious bodily injury; using a motor vehicle in commission of a felony; being a driver under 21 operating a vehicle with a breath-alcohol level of 0.02% or higher; and having illegal window tinting.
He was sentenced last month to eight months in jail after he pleaded no contest to reckless driving. He also received five years of probation and surrendered his driving privileges for three years.
