The offender was found guilty of dangerous driving causing bodily harm after crossing the centre line at high speed and causing a head-on collision that resulted in catastrophic injuries to another driver.
The offender had been experiencing significant sleep deficits and fell asleep at the wheel.
The Crown sought a one-year custodial sentence, while the offender sought an 18-month conditional sentence order.
The court found that a conditional sentence would not adequately address the need for deterrence and denunciation, given the offender's choice to drive while severely sleep-deprived.
The offender was sentenced to one year in jail and a three-year driving prohibition.
