Another serious Easter road crash as SA Police test thousands of drivers A WOMAN is in a critical condition after a two-car crash at Woodville South. The Gawler woman, aged in her 40s, was driving a white Holden Commodore station wagon which collided with a blue Mitsubishi sedan at the intersection of Port Rd and Woodville Rd, about 7.15pm on Saturday. She was taken to the Royal Adelaide Hospital with life-threatening injuries. Major Crash investigators have arrested a West Lakes man, 27, who suffered a broken ankle in the crash, and charged him with causing serious injury by dangerous driving. Police said he was unlicensed and driving an unregistered vehicle. He was refused bail and is expected to appear in the Adelaide Magistrates Court on Tuesday. A woman has life-threatening injuries after this crash at Woodville South on Saturday night. Passengers in both vehicles escaped with only minor injuries. On Saturday, 17-year-old Dylan Poulton was killed in a road crash at Balaklava. On Friday, a man and a woman were killed in a horrific head-on crash near Ki-Ki. Police are urging all road users to take care during the Easter holidays with increased numbers of people on the roads. South Australia has already recorded its equal worst Easter road toll in recent years - so far the same as 2010 - with three people killed since Thursday. Overnight, police conducting Operation Crossroads - targeting drink and drug driving - detected 46 drink drivers and 16 people committing drug related offences from almost 3900 tests. Police issued 36 motorists with an immediate loss of the driver's licence and 34 vehicles were impounded or clamped for 28 days. In one incident, police witnessed a female passenger cradling a newborn baby in her arms as the driver pulled into a testing station on Glen Osmond Rd at Fullarton. The driver was issued with an expiation notice for not securing the child in an approved child restraint. "The consequences to an unrestrained child involved in even a minor crash could be fatal," police said. In another incident, an unlicensed male driver allegedly recorded a blood alcohol reading of 0.223 - more than four times the legal blood alcohol limit - at Gilles Plains. Traffic Support Branch acting officer-in-charge Detective Inspector Peter Duance said: "Despite repeated publicity and warnings, it is disappointing that so many motorists continue to drink and drug drive. These people show little regard for their safety and that of others. Their poor choices placed themselves and all of us at risk.
