The Hairspray star’s car was impounded shortly after the run-in with cops in Burbank, California and Bynes was cited for driving on a suspended licence.
She now faces possible jail time for ignoring warnings to stop driving, according to TMZ.com.
Bynes is also currently facing a DUI charge and two hit-and-run charges following other car-related incidents earlier this year (12).
A Los Angeles judge told Bynes on Wednesday (19Sep12) she faces jail time if she is pulled over by traffic cops again. She is due to stand trial for the DUI and hit-and-run charges on 29 October (12).
