Officer DiAria is a police officer only seen in Ready, Set, Don't Drive. While Miley is on her way to a party, he pulls over Miley for having her turn signal on for a mile and a half. After he asks to see Miley's license, he takes her to jail, as she obtained the license as Hannah Montana, not as Miley Stewart. To get out of jail, Miley had to prove to his daughter Kelsey, the ultimate Hannah Montana fan, that she really was Hannah Montana, revealing her secret to her. Miley mistakenly pronounces his name "diarrhea", which he corrects as being pronounced "dee-aria".
He is portrayed by Wayne Wilderson.
