The 54-year-old pharmacist blew five times the legal blood alcohol limit in the aftermath of the wreck, after she turned "directly" into the path of an oncoming car just 300m from her home on April 1 last year.

During a mention in Tamworth District Court last week, Crown prosecutor Matt Coates said Anderson would need to attend court when her sentence is handed down in about three weeks.

"The Crown's submitting she would have to appear in person," he told the court.

He said written submissions could be handed up to the judge for consideration the week before.

Judge Deborah Payne set the sentencing hearing for mid-May and told lawyers she may reserve her judgement.

"I've got the next day as back-up if I need it," she said.

Anderson will be sentenced on the single charge of aggravated dangerous driving occasioning grievous bodily harm.

The offence can carry a maximum penalty of 11 years behind bars.

A set of agreed facts - tendered to the court when she pleaded guilty last year - show Anderson failed to give way as she turned her Volkswagen Tiguan right off White Street.

She turned into the path of a 57-year-old woman, who was travelling the other way in a Ford Focus at about 2pm.

A senior constable in the highway patrol squad witnessed the crash and captured it on his in-car camera.

He stopped to check on the drivers before calling for ambulance and police support.

He claimed Anderson said she was "fine" and hadn't seen the other driver coming.

He said she appeared "unsteady" on her feet as she got out of the car.

When asked at the scene if she'd had anything to drink, Anderson initially said "no", that she'd been "at work".

She was arrested after a positive roadside test and recorded a high-range blood alcohol reading of 0.250 at the police station.

Days later, Anderson told police she had checked her rearview mirror before making the right-hand turn, and next thing she knew the airbags were going off.

The victim was taken to Tamworth hospital and underwent surgery for a broken arm.

The agreed facts indicate that at least four months after the crash, the victim still had not been able to go back to work.

The facts said she took painkillers daily and suffered constant pain in her arm.

The case was adjourned to Tamworth District Court.
