The What I Like About You actress was asked to stop her car on the side of the road by law enforcement officers in Los Angeles because she was driving without her headlights on.
The incident occurred last night (September 10), after her driver's license was thought to have been suspended last week.
Sources told TMZ that while Bynes did not end up in custody, she was spoken to by the officers and sent on her way.
It is unclear if officers ran a check on the screen star's license, but she was recently given two misdemeanor hit-and-run charges - reportedly causing her driving licence to be revoked.
Bynes also refused to take a breathalyzer test after being caught driving under the influence, which results in an automatic one-year license suspension.
She has pleaded not guilty plea to the DUI charge.
