Lindsay Lohan is in an unmarked police car, being escorted by two other unmarked cars, on her way to Lynwood Correctional Facility just east of downtown Los Angeles.

Lindsay was ducking down in the back seat of the cruiser, covered by a white sheet, as the trio of cars proceeded from the LAX Courthouse to her final destination, where she will be booked and released.

UPDATE: Lindsay posted $75,000 after spending about 5 hours at the jail, and was released. She's due back in court May 11 for a pretrial hearing.
