A man has been reported for drink-driving after being stopped at Whyalla Stuart on the weekend.
Police stopped a vehicle on Nicolson Avenue at about 1.20am on Saturday to conduct a mobile driver screening test.
The driver, who was the holder of a provisional driver's licence, allegedly produced a blood alcohol reading of 0.143 - nearly three times the legal limit.
A 22-year-old man from Western Australia was reported for drink-driving and breaching a condition of his provisional licence.
He was issued with a six-month instant loss of licence notice and will be summoned to appear in the Whyalla Magistrates Court at a later date.
