Stephanie Pratt reached a plea deal with Los Angeles prosecutors in her DUI case Thursday.
The Hills star, 23, was sentenced to three years informal probation, completion of a 12-week alcohol education program, as well as three Alcoholics Anonymous meetings a week for eight weeks, and will pay a fine.
DUI charges were dropped in exchange for a no contest plea to one count of misdemeanor “exhibition of speed.”
On the issue of whether she attended rehab, “Ms. Pratt voluntarily sought help from a doctor regarding substance issues but the doctor recommended that she didn’t need rehab,” Pratt’s lawyer Jon Bryant Artz tells PEOPLE.
Following her Oct. 18 arrest, in which she was pulled over after attending Holly Montag‘s birthday party, Pratt said the incident “was the worst thing to happen to me and, at the same time, it was the biggest blessing” as a life lesson.
