A Gold Coast mother has set a state record for drink driving after blowing eight times the limit GUILTY PLEA: A remorseful Janet Sarah Waterhouse leaves Southport Magistrates Court yesterday. A GOLD Coast mum has set a Queensland record for drink-driving, with a reading of 0.425 per cent. An embarrassed and remorseful Janet Sarah Waterhouse yesterday pleaded guilty in Southport Magistrates Court to high range drink-driving. The mother of two teenagers was placed on a two-year probation and banned from driving for 15 months. Waterhouse admitted drinking 500ml of straight vodka late on May 10 last year. About noon the next day she drove to her local shops on Ferry Rd to buy more alcohol.

Police tracked Waterhouse to her Ridgeway Ave home and breath-tested her at 1.35pm. Under the Transport Operations (Road Use Management) Act 1995, police can legally test people for suspected drunkenness up to three hours after an offence has been committed. Solicitor Mark Bamberry said Waterhouse had consumed another 500ml of vodka at home by the time police breath-tested her. Forensic experts calculated that although her reading was 0.425 - eight times the legal limit - she would have been five to six times over the limit when behind the wheel. Solicitor Mark Bamberry said Waterhouse had consumed another 500ml of vodka at home before police arrived to breath test her. He said she was drinking to cope with issues in her de-facto relationship and repercussions from childhood indecent assaults by her former swimming coach. "She was drowning her sorrows with alcohol," he said. Magistrate John Costanzo said a lengthy probation term, accompanied by counselling and driving courses, would help protect the community. "Anyone driving with that amount of alcohol in their system is simply a risk to themselves, every road user and member of the public in the vicinity," he said. It was simply good luck and not good management that you didn't have a serious accident or kill someone. He commended her for staying off the roads for the past nine months and beginning counselling session of her own accord. Outside court Waterhouse declined to comment. Mr Bamberry said her case highlighted the need for people to be aware that drinking after driving could still land them in court. "The legislation allows for police to test you up to three hours after you have committed a driving offence and your result can be used against you in court," he said.
