A man driving nearly 90km/h in a 40km/h zone on an Alice Springs road last Sunday was arrested after failing a roadside breath test, NT Police said, but was too drunk to complete a full breath analysis at the watch house.

The 30-year-old man is facing dangerous driving charges after he was detected speeding by police, doing 89km/h on an undisclosed Alice Springs road at 2:30am on February 12.

“The vehicle was pulled over and the man was subject to an initial roadside breath test, where he tested positive,” said Senior Sergeant Rob Engels.

“He was arrested and conveyed to the Alice Springs Watch House where he was unable to complete a breath analysis due to his level of intoxication.”

The man was charged with driving at a dangerous speed – exceeding speed by 45 kilometres and failing to supply a sufficient sample of breath for breath analysis.

He was bailed to appear in court on March 1.

“This is a frightening example of someone selfishly putting everyone on our roads at risk,” Snr Sgt Engels said.

“This person has not only made the terrible and dangerous decision to drive whilst intoxicated, he has then sped along a heavily used street at more than twice the speed limit.

“Random breath testing and speed detection will be continuing on Territory Roads as we continue to work to combat the Fatal Five and support good driver behaviours.”
