Half of young drivers admit to sometimes not giving their full concentration when behind the wheel.
A survey by the Institute of Advanced Motorists (IAM) and Vision Critical found a worrying 50 per cent of motorists aged 18-24 said they do not concentrate 100 per cent of the time.
The survey of 1,500 motorists found that in total, just 60 per cent said they concentrate all of the time when they are driving.
Older drivers seem the most focused when behind the wheel, with 73 per cent of over 65 year-olds claiming to always concentrate.
Signs of not concentrating commonplace
Around 26 per cent said they concentrate most of the time.
Some 47 per cent of drivers aged 24-34 admit to not concentrating.
IAM chief executive Simon Best said: "Signs of not concentrating such as missed turnings or uncancelled indicator lights are commonplace.
"Simply not concentrating is a key cause of crashes yet it is not borne out in statistics because drivers rarely admit to it in police reports or on insurance forms."
"These results reconfirm stereotypes surrounding younger drivers and the ease with which they can be distracted away from staying safe."
Daydreaming blamed for lapses in focus
Almost of quarter (24 per cent) of those drivers who do not fully concentrate blame daydreaming for their lapses in focus.
This figure rises to 30 per cent amongst 18-24 year-olds.
The other main reasons for losing concentration include stress (22 per cent), thinking about what you will be doing when you arrive (21 per cent) and thinking about relationships with family, friends (21 per cent).
People living and working in London are the most likely to be distracted while driving, with almost half (47 per cent) admitting to lapses in concentration.
In Yorkshire and Humberside, the South West and Scotland the figure was 46 per cent.
