A COODANUP man was arrested on Friday afternoon after a road side breath test resulted in a reading of 0.4 per cent which is eight times more than the legal limit.
A later test returned a reading of 0.186 per cent, and the man was arrested and charged.
The 54-year-old man was tested by Mt Barker police after 5.30pm, after an off-duty police officer claimed he witnessed the man lose control of his car and skid across Albany Highway.
The off-duty officer asked for the help of Mt Barker police because he was suspicious the Coodanup man was intoxicated.
Mt Barker police attended and subjected the man to a preliminary breath test which is when they tweeted that the driver had registered 0.4 per cent.

Police believe the extraordinarily high reading could have been due to recent alcohol consumption.
The Coodanup man was taken back to Mt Barker Police Station to undergo a formal breath test which returned a reading of 0.186 per cent.
He was charged with driving an unlicensed car, exceeding 0.18 grams of alcohol per 100ml of blood, having no authority to drive.
His car was seized and he will appear in Albany Court on April 5.
