Drivers could soon have their blood tested for tiredness and face prosecution for being sleepy at the wheel following new research.
Motorists who cause crashes would face the new blood test as a result of the study funded by the Australian Government Office of Road Safety - which could be rolled out within two years, it is reported.
It comes as around half of drivers have admitted using their vehicle having had insufficient sleep - less than five hours - and the charity Brake has said that up to 20% of crashes could be caused by fatigue.
