A third in a recent poll of 1,000 drivers said they were distracted once a month or more and 50% said they had eaten a meal while driving.
The findings, from a report Driven to Distraction? by road safety charity Brake and Green Flag, also showed that 27% admitted changing CDs while in free-flowing traffic.
Green Flag spokesman Nigel Charlesworth said: ‘Drivers need to remember just how important it is to concentrate on driving as driver distraction causes so many road crashes.
‘It’s important for drivers to keep their eyes on the road at all times and avoid putting themselves, passengers and other road users at risk.’
