Katie Allan, a 20 year old student who was studying at the University of Glasgow, had consumed four pints of cider before driving home from a pub, has been jailed for 16 months after she hit a 15-year-old boy, who was out running.
The runner was left unconscious and bleeding, with a broken ankle and a fractured eye socket.
Allen left the scene of the collison but a witness passed on her car registration to police, who found at home.
She pled guilty to causing serious injury to the teenager by driving dangerously, and driving with 87 microgrammes of alcohol in 100ml of breath - more than four-times the legal limit.
Defence solicitor Amy Spencer asked for leniency for her client, but Sheriff David Pender ruled there was only one appropriate sentence - and jailed Allan for 16 months.
She was banned from driving for four years and will have to sit and pass the extended test before she can drive again.
