Bradley Bullock, 50, sustained fatal injuries on Stoneywood Street in Fernvale, about 60 kilometres east of Brisbane, on Sunday afternoon following reports of a disturbance.
Lacey-Jay Bullock, 45, was charged with murder and driving while disqualified.
She was not required to appear in person for the brief hearing on Tuesday. Her duty solicitor requested a three-week adjournment and did not make an application for bail.
Magistrate Jason Schubert remanded Mrs Bullock in custody, ordering the matter back to court on October 21. Members of her family were in the courtroom during the short proceeding.
