The family of an 18-year-old woman killed in a quad bike crash say the four-year prison sentence handed to the man responsible for the accident is "disgusting".
Joshua Wayne Bonjour, 22, was convicted after a trial and sentenced in the Perth District Court on Thursday for dangerous driving causing the death of Jodie Maree Worthington.
Ms Worthington was a pillion passenger on Bonjour's quad bike when it struck a car on a dirt track in Lancelin, north of Perth, in September 2012.
The court heard Ms Worthington was not wearing a helmet, the bike was not designed to carry passengers or more than 100kg, and Bonjour was speeding.
"I have no reasonable doubt that had you been travelling at a proper speed and under control, there would have been no collision at all," Judge Patrick O'Neal said.
"You were intentionally driving in a reckless way for the thrill of it."
Judge O'Neal referenced six victim impact statements and said Ms Worthington's family felt understandable anguish, devastation and were inconsolable.
At the time of the crash, Bonjour was on a four-year suspended jail term for other offences.
An extra 18 months jail was imposed for those crimes, bringing Bonjour's total sentence to five-and-a-half years.
Bonjour must serve at least three-and-a-half years behind bars before being eligible for parole.
A post on a memorial Facebook page for Ms Worthington read: "This is disgusting, would get more for stealing her car."
Despite his record, the judge said Bonjour had good prospects for rehabilitation.
"I accept that you feel some sense of guilt," Judge O'Neal said.
"You'd be a monster if you did not feel sorry for her death and I do not believe that you are a monster."
