Bynes' lawyer, Rich Hutton, issued the plea on her behalf. In addition to being placed on probation, the actress was also fined $300.
The former Nickelodeon star was charged with driving on a suspended license in September 2012 after being pulled over. Bynes' license had been suspended following two hit-and-run charges filed against her, which were later settled.
The actress, who now lives in New York, still faces charges stemming from her April 2012 DUI arrest. Bynes entered a plea of "not guilty," and shortly after the incident she tweeted President Barack Obama for help.
"Hey Barack Obama ... I don't drink," she wrote. "Please fire the cop who arrested me. I also don't hit and run. The end."
