What is the consequences of a young woman driving under the influence of alcohol driving after a night out?

In R v. Cook, 2013 SKPC 161, the 22‑year‑old offender had been drinking alcohol with friends. She retrieved her vehicle and on her way home drove over the victim, who was passed out in the middle of the road. She fled the scene. After an extensive investigation, the police determined her to be a suspect. She initially denied responsibility but later confessed. She had no prior criminal antecedents. She received a 90‑day jail sentence to be served intermittently, plus 18 months of probation and a two‑year driving prohibition.
