Santa Monica Deputy City Attorney Melanie Skehar says Pressly's attorney entered the plea Thursday for the former star of "My Name is Earl."
Pressly was also ordered to attend a six-month alcohol education class. Skehar says the Department of Motor Vehicles is also requiring an ignition locking device be installed on her car.
Pressly was arrested Jan. 5 after police say she was stopped for a traffic violation and charged with driving while having a blood alcohol content of more than .20. The legal limit is .08.
Her attorney, Richard Hutton, did not immediately return a phone message seeking comment.
