Driver lost control of Jaguar X-Type and hit two pedestrians
Hilda Lumsden-Gill claimed she had suffered a seizure but was told the crash was her own fault.
A motorist seriously injured two pedestrians after mounting the pavement.
Hilda Lumsden-Gill was charged with dangerous driving after losing control of her Jaguar X-Type and crashing into a parked Ford Ranger pick-up truck on Bogie Street in Huntly, Aberdeenshire.
She claimed to have suffered an epileptic seizure but a judge told her the crash had been "entirely" her own fault.
The 59-year-old's vehicle mounted the pavement, striking mother-of-four Pauline Thomson, who was thrown on to the car bonnet.
The car continued to drive along the road with Ms Thomson still on top of the vehicle before knocking over another pedestrian, Georgina Couper, who was standing on the pavement.
Ms Thomson was airlifted to hospital suffering from a fractured skull and severe brain injury, while Ms Couper was left with a fractured ankle and bruising to her head and body after the incident in May 2014.
On Monday, Lumsden-Gill was banned from driving for life at Aberdeen Sheriff Court.
The former community council chairwoman had denied the allegations during her trial in June.
She had lodged a special defence of being in a state of automatism claiming she had suffered a "complex partial seizure" - a type of epileptic episode - while behind the wheel.
"For the avoidance of doubt, this accident was your own fault, entirely your own fault and only your fault."Sheriff William Summers
Sheriff William Summers said he was concerned about her failure to recognise her responsibility for the accident.
He said: "For the avoidance of doubt, this accident was your own fault, entirely your own fault and only your fault."
The sheriff told the court the two pedestrians had suffered life-changing injuries and were likely to be physically and emotionally scarred for the rest of their lives.
During the trial Mrs Lumsden-Gill told a jury she had suffered from seizures occasionally since 1996 and despite MRIs and scans being carried out doctors could never give her a proper diagnosis.
On three occasions between her first fit and the collision, she had voluntarily handed over her licence to the DVLA.
More than three years had passed since she had suffered an episode, although she had been seen having a "bad turn" during a community trust meeting the month before.
She told the court while giving evidence: "If I had been aware, I would have reported it to my doctor and I would not have driven.
"I would have been worried about the safety of not only myself but of the general public."
Lumsden-Gill handed in her resignation for her role as chairwoman of Huntly Community Council after she was found guilty of dangerous driving.
She has now been banned from driving for life and will have to undertake 300 hours of unpaid work as part of her sentence.
