Driving while tired is as dangerous as drink-driving, study finds

A new international study has thrown up some terrifying evidence for anybody who's ever got into the car while tired. It found that taking getting behind the wheel while sleep-deprived could be just as dangerous as driving while intoxicated.

The study, lead by Dr Itzhak Fried from the University of California, found that parts of the brain can shut themselves off in people who are particularly tired – leading people to struggle to connect visual information with conscious thought.
