Petty was charged today with DUI with injury, DUI with a blood alcohol level of .08 or higher with injuries and with having no proof of financial responsibility -- meaning she had no insurance.
The first two charges carry a maximum penalty of one year in county jail and up to $1,000 in fines each. The insurance infraction could cost up to $200.
Petty allegedly hit a skateboarder with her car in Venice, Calif. last Saturday. Both suffered only minor injuries.
Petty is due back in court on June 25.
