A shocking four in ten British drivers admit they have fallen asleep at the wheel, a survey has revealed.
In a study of more than 1,000 drivers, vehicle-leasing company OSV Ltd discovered that 38 per cent said they had either nodded off or fallen asleep while driving. An additional 36 per cent believed they have put other motorists at danger driving while tired.
Over half the motorists say they ignore official guidance to take a break every two hours on long journeys with one in five drivers stating that they carry on even when they know they're overtired.
This alarming statistic comes in spite of the fact that a quarter of all crashes that cause death or serious injury in Britain are tiredness related.
Debbie Kirkley, co-founder of OSV Ltd, said: "Tired drivers are a huge danger to not only themselves but other drivers and passengers on the roads.
"Drivers should never drive whilst overtired and should always plan their journeys carefully to include regular rest breaks - minimum of 15 minutes every two hours."
In reality, 81% only stop because they need a toilet break or are hungry: a mere 25% actually stop because they feel they're tired.
Drivers deal with their tiredness behind the wheel by other mans, with more than three quarters of drivers admit to drinking coffee or water, turning the radio up or eat. Solutions that are usually ineffective, states Kirkley.
The study revealed that female drivers were more likely to stop for regular breaks while driving, but were more likely to doze off or fall asleep at the wheel.
More men than women believe they have out themselves or others at risk while driving overtired, as men were more likely to drive while overtired.
