Ms Hansen was killed and 11 other people including an 18-month old baby were injured when a car driven by learner driver Rose Deng, 42, veered onto the footpath and into a queue of people wating for a bus near the intersection of Railway Parade and Montgomery Street in March last year.

Deputy State Coroner Malcolm Macpherson will deliver his recommendations when the NSW Coroner's Court reconvenes at 2pm.

In his closing submission this morning, Ms Deng's legal counsel Mark Ierace SC said there was no evidence Ms Deng had lied about her mental health when applying for a learner driver's permit.

''There no evidence to suggest she was aware Post Traumatic Stress Disorder, which she had endured as a result of her experiences in Africa, would affect her driving,'' he said.

''More to the point, there's no evidence it was a significant contributing factor to this event.''

Mr Ierace said although Ms Deng's PTSD could not be said to have contributed to the crash, it had a severe impact on her immediately following Ms Hansen's death.

''There can be no doubt that as a result of this incident she experienced extreme trauma,'' he said,

''She literally pulled her hair out, clumps of her hair were found in the road, she punched her face, she threw her head against the gutter.

''Once the accident occurred, her central role in the death of Ms Hansen immediately combined with her earlier distresses.''

He asked Mr Macpherson to recommend the Roads and Traffic Authority investigate writing guidelines for lay driving instructors setting out the best method of stopping a car in an emergency.

Ms Deng's driving supervisor at the time of the crash, John Tittmarsh, had previously told the court he had attempted to reach across Ms Deng to turn off the ignition.

Evidence given by a police expert had suggested the fasted way to stop the car may have been to put it in nuetral and engage the handbrake.

''If it is determined to be an additional measure that can be placed at the disposal of lay driving instructors (to stop cars in emergency situations) then it should be,'' Mr Ierace said.

Counsel assisting the Coroner, Melanie Cage, suggested in her submission the ''12 tips for learner drivers'' currently available on the Roads and Traffic Authority website be included in future editions of the learner driver's handbook.

Counsel for the Authority, Chris Ronalds SC, said the tips would be included in the next print run in three to four months time and in all subsequent editions.
