Payne, of Brandreth Close, Dickleburgh, near Diss, appeared at court on Wednesday (December 16) having previously admitted driving dangerously on October 13 this year.
Dave Foulkes, mitigating, said it was a “sad case”.
He said: “This is not a case of someone deliberately going out and driving badly and causing a risk to themselves and others.”
He said the victim was “very vulnerable” due to her mental health and had gone to hospital due to concerns about herself but was sent away.
