Test to detect sleep-deprived drivers is on the way
Around a quarter of fatal traffic accidents are estimated to involve a sleep-deprived driver. Scientists are working on a test that can determine if you've been up for 24 hours straight. Right now it's a blood test, but in the future could it work in a similar way to a breathalyser, which checks whether you're over the blood-alcohol limit?
Professor Clare Anderson from Monash University in the Australian city of Melbourne is leading the efforts to develop such a test and told Newshour's Tim Franks more about it.
