Driver acquitted over WA crash death

An alleged drunk driver who fatally struck a drug-affected motorcyclist in Perth has been cleared of being criminally responsible.

Patricia Connie Peters stood trial in the West Australian District Court accused of dangerous drunk driving causing the death of 23-year-old Damir Nezic at a Morley intersection in June 2017, but was found not guilty this week.

Ms Peters, then aged 37, had an alcohol reading of 0.186 per cent while Mr Nezic had methylamphetamine in his system, the court heard.

Mr Nezic's helmet came off during the collision and he died at Royal Perth Hospital from multiple injuries.

One witness became emotional while testifying about the "traumatic" incident, saying he saw Mr Nezic overtake him and at the same time Ms Peters began moving her car at the intersection.

Ms Peters will face Perth Magistrates Court next week charged with driving a motor vehicle under the influence of alcohol.
