Man seriously hurt in quad bike crash at Gillman A MAN is in hospital in a serious condition after a quad bike crash at Gillman. SA Ambulance Service crews were called to the Grand Trunkway about 3.40pm after reports the quad bike the man was riding crashed into a pole. The man, 33, was taken to the Royal Adelaide Hospital in a critical condition with spine and arm injuries, an SA Ambulance Service spokeswoman said. He is now listed as being in serious condition. Attorney-General John Rau this morning issued a plea for quad bike users to be wary of dangers because of a spike in crashes across the country. "I am seriously concerned by the fact that quad bikes are increasingly a cause of horrific injury and death across the nation," he said. Safe Work Australia statistics show there have been seven quad bike fatalities so far this year, four of those at work and three during recreational use. There were 19 fatalities nationally in 2012. "I urge all South Australians to assess the risks of quad bikes and use any necessary precautions," Mr Rau said.
