More than one in seven drivers admit they regularly suffer memory blanks on the road, according to a study.

A poll of more than 27,000 motorists found that 15% are quite often or very often not able to recall the last few moments of their journey.

Motoring organisation the AA, which commissioned the research, warned that the figure could indicate that drivers need to concentrate more.

The worst-affected age group was 25 to 34-year-olds, with almost a quarter (24%) admitting to regular memory blanks.

Just 9% of drivers aged over 65 said they suffered from the problem.

Women drivers (17%) were more likely to admit memory blanks than men (13%).

AA president Edmund King said the blanks may be due to drivers being distracted by phone calls, passenger conversations, listening to the radio or simply day-dreaming.

He said: 'Motoring memory blanks may be an indication that the driver is not concentrating on the road ahead.

'It is good practice as a driver to question yourself as to whether you could safely stop if a child walked out from behind that parked car. Many drivers also go on to autopilot when they are close to home after a long journey, and that is a good time to remind yourself to concentrate harder to get home safely.'

According to Government figures, the most common contributory factor in road accidents and casualties is people failing to look. The latest statistics show this occurred in 44% of accidents in 2014, up from 32% in 2005.
