Crash a reminder to take care over Easter THE narrow escape of three small children in a car crash in Sydney's northwest is a reminder to motorists to take care over the Easter break, says NSW Police Commissioner Andrew Scipione. The children, aged one, three and five, suffered various injuries, including a fractured arm and facial injuries when their car crashed into the rail at a West Pennant Hills intersection at 2.20am (AEDT) on Tuesday. Their mother, who was believed to be suffering from fatigue, was unhurt. Inspector Wayne Chaffey says the children, who were taken to Westmead Children's Hospital, were "lucky to be alive" after a guard rail pierced the windscreen and speared into the back of the car. "At this stage speed and alcohol aren't a contributing factor and police will be looking at it in regards to fatigue," Insp Chaffey told Macquarie Radio. Mr Scipione said that driving tired was a major road risk. "As we move towards Easter certainly we know that fatigue is one of the big four killers," he told reporters in Sydney. Our biggest problems on our roads: seatbelts, speeding, alcohol and fatigue. Fatigue accounts for a lot of deaths. My advice has been and always will be, particularly young people who are involved in fatigue-related crashes, if you are going to have a crash I would rather you crash on your mates lounge rather than into the telegraph pole and kill yourself or someone else. Please if you are tired, don't drive.
