NASCAR driver Kurt Busch's ex-girlfriend is delivering emotional testimony in a Delaware courtroom, seeking an order that Busch stay away from her following an alleged assault.

Patricia Driscoll testified Tuesday that Busch had choked her and smashed her head into a wall in September at Dover International Speedway. The 36-year-old sobbed during her testimony, and the judge ordered a break.

Driscoll has filed court documents asking that a judge order Busch to stay away from her and not contact her. She also is asking that Busch undergo a psychiatric evaluation and be evaluated by a certified domestic violence treatment agency.

Attorneys for the 36-year-old Busch have denied the allegations, which also are the subject of a separate criminal investigation by Dover police.
