South Australia Police have reported a woman for drink driving after she was stopped on the Stuart Highway at Coober Pedy earlier this week.

Just before midnight on Wednesday, 27 August, police pulled over a Holden ute travelling south of the town as part of routine patrols. The driver, a 37-year-old woman from Peterhead, returned a positive breath test.

Further testing allegedly showed a blood alcohol reading of 0.172, more than three times the legal limit. Checks also revealed the woman was disqualified from driving at the time.

She was reported for drink driving and driving while disqualified, her licence was immediately disqualified for 12 months, and her vehicle was impounded for 28 days.

The woman will be summonsed to appear in court at a later date.

Police have reminded motorists that drink driving poses a serious risk to all road users and will not be tolerated on South Australian roads.
