'Whoa!' Man's breath test returns 'biologically impossible' result

A driver in Western Australia has shocked police after returning a random breath test more than six times the legal limit.

The driver underwent a breath test on Sunday morning about 3.16am in Derby in the Kimberley region.

He returned a blood-alcohol level of 0.341, which is more than six times the drink driving limit of 0.05.

Derby Police said the alcohol level in the man’s breath “biologically shouldn’t be possible”.

“It is like driving whilst under a surgical anaesthetic or being in a coma,” Derby Police tweeted.

Police added the driver has two prior life disqualifications.

The tweet has been liked more than 570 times with more than 320 re-tweets.

“Time to start crushing cars,” one woman tweeted. 

Another simply tweeted “whoah”.
