Many of us suffer from lack of sleep, so I thought this story might be of interest.
The link to the full story quoting authorities in Australia, the US and the UK is at the bottom, but in case you can't access that here's the opening :
"A blood test to measure whether a driver who has caused an accident was impaired by lack of sleep could be available within two years, making it easier to legislate against drowsy drivers or their employers.
The research, funded by the Australian Government Office of Road Safety, comes as fresh evidence suggests that driving on less than five hours’ sleep is as dangerous as being over the legal drink-drive limit in many countries.
It could also provide a “line in the sand” that could enable people to be prosecuted for driving while fatigued, which many sleep experts are calling for."
This is the link to the full story from The Guardian - unsure whether this can be read by members outside the UK:
