'Tanked Girl' Lori Petty Pleads No Contest to DUI

Lori Petty just pled no contest to DUI with injury over her drunken driving arrest back in May -- the one in which she allegedly hit a skateboarder with her car.

The other two charges -- having no proof of financial responsibility (no insurance) and DUI with a blood alcohol level of .08 or higher -- were dismissed.

Petty -- who was arrested on May 30 in Venice, CA -- received 60 months probation, $100 in court fees and $395 in fines and penalties.

Petty also agreed to complete a 60 day outpatient alcohol treatment program -- she already has 30 days in the bag.
