The number of drivers momentarily falling asleep behind the wheel is "horrifying" and more needs to be done to make sure motorists "get sufficient sleep" before taking to the road, a charity has said.
Brake deputy chief executive Julie Townsend said:
The fact that so many drivers - especially men - have head-nodded at the wheel is horrifying, even more so that many don't recognise this means they have fallen asleep briefly.
This survey suggests this is down to many people failing to ensure they always get sufficient sleep before embarking on journeys.
We need all drivers to wake up to the fact that "head nodding" is falling asleep, and can easily lead to catastrophe, but it can, of course be prevented.
