A Charlottetown teenager wants P.E.I. drivers to stop speeding on Island highways, and is making plans to share her story of almost dying in a high-speed accident.

'You could kill yourself; kill your friends; kill other people.' — Katie Banks

Katie Banks, 17, suffered serious injuries in June when the car she was in flipped on a highway near Montague. On Friday the driver of that vehicle, 20-year-old Jonathan Tyler MacKay of Hunter River, pleaded guilty to a charge of dangerous driving causing bodily harm.

Months after the accident her father, Warren Banks, forced himself to go to the junkyard to look at the vehicle that Katie was in.

"This one shows pretty well half a car," he said while showing the pictures to CBC News.

" I came pretty close to losing my 17-year-old to just outright, plain stupidity."

An RCMP collision analyst estimated MacKay was driving 176 km/h when he crashed. MacKay had a severe concussion, but Banks suffered far worse. She had broken bones in her back, neck, pelvis and ankle and spent months in the Queen Elizabeth Hospital in Charlottetown. Doctors say she may always walk with a limp.

Banks said when she's recovered physically she wants to tell other teens about the importance of wearing a seatbelt and about the dangers of speeding.   "I just want people to know that a seatbelt did save my life and speeding is just wrong," she said.

"You could kill yourself; kill your friends; kill other people."

MacKay will be sentenced on the dangerous driving conviction in March.
