A 46-year-old man from Beaumont has lost his licence for a year, after he was caught drink-driving in the middle of the day on Wednesday. 

Police were alerted to an erratic Mercedes-Benz on Victor Harbor Road around 12:30pm, after a member of the public claimed the driver was involved in several near-misses. 

The man was later stopped on the Southern Expressway. 

A breath test revealed a .171 alcohol reading, prompting a 12-month loss of licence and a 28-day impoundment of his vehicle. 

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

Police are urging anyone with dash-cam footage of the driver to assist with their investigation by calling Crime Stoppers on 1800 333 000.
