Lohan checked into the posh Promises rehabilitation facility in Malibu after the incident. She left the facility July 13 after six weeks of treatment. She was photographed wearing an alcohol-monitoring ankle bracelet after her release.
Lohan was arrested again on July 24 following a 911 call by Michelle Peck, the mother of Lohan's former personal assistant. Peck told police she was being chased by an SUV. Police later said Lohan was the driver, said Michael Bialys, Los Angeles DUI lawyer.
Lohan's blood-alcohol level was between 0.12 and 0.13 percent when police found her, officials said. Police also found a white powder in her pocket that was determined to be .02 grams of cocaine.
Lohan started 2007 in rehab at the Wonderland Center in Los Angeles.
