Police have arrested four high-range drink drivers in Murray Bridge and Mannum during the past week.
A 50-year-old Murray Bridge man was stopped on Thomas Street just after 12.30am on Wednesday, April 8, and allegedly returned a blood alcohol reading of 0.198, almost four times the legal limit.
A 27-year-old Murray Bridge man allegedly blew 0.187 after being stopped on Galway Avenue around 12.20am on Monday, April 6.
A 51-year-old Mannum man was pulled over on that town's main street at 12.25pm on Sunday, April 5 and allegedly blew 0.227.
A 46-year-old Murray Bridge man breath-tested on Swanport Road at 12.40am on Saturday, April 4 allegedly produced a reading of 0.158, more than three times the limit.
Each of the four drivers had his car impounded for 28 days, lost his licence for 12 months on the spot, was reported for drink driving, and was told to expect a court summons.
The 27-year-old was also reported for driving unlicensed, as he had never held one.
