A new survey has found that 36% of motorists still admit to using a hand-held mobile phone while driving their car, with a quarter saying they've done so in the past week.
However, the true figure could be much higher as 93% of motorists say they've seen someone else using a mobile phone at the wheel in the past seven days.
In spite of tougher penalties being introduced in 2007, which include the threat of jail if a driver is prosecuted for dangerous driving, there has been no drop in the number admitting to using a hand-held mobile over the past year.
Last year's survey also showed that 36% admit to using their phone while driving.
Only a slight drop of 6% has been recorded since 2005.
Steve Fowler, editor of What Car?, whcih carried out the survey said: "The message is obviously not getting through - if you use a hand-held mobile phone while driving, you may end up killing yourself or others.
"Research has shown that using a mobile phone at the wheel could be more dangerous than drink driving.
"Yet it seems you don't have to travel far to see someone who's oblivious to the dangers - they're all too easy to spot by their bad driving habits."
