Lindsay Lohan was arrested for drunk driving early Tuesday morning–her second DUI arrest in less than three months. Lohan was charged for possession of cocaine (a stash was found her in pocket), driving under the influence and driving with a suspended license. TMZ.com reported that Lohan refused a Preliminary Alcohol Screening Device after failing a walk-the-line test, but when her blood alcohol level was later tested at the police station, it was well over the California legal limit. Interestingly, at the time, she wasn’t wearing the SCRAM alcohol monitoring device on her ankle that she’d voluntarily agreed to wear upon release from rehab. Lohan faces up to six years in jail if convicted of all charges.
