[bbc] More drivers are using hand-held mobile phones than before tougher penalties were introduced two years ago, the Transport Research Laboratory has said.
It found 2.6% of car drivers used hand-held phones in 2006 - when fines rose to £60 and three points could be added to licences - compared with 2.8% now.
Phone-using drivers are four times more likely to crash, the TRL added.
Ministers say work continues to highlight the dangers. The TRL study involved more than 14,000 vehicles.
The report's authors believe there is no reason to think the picture at the 30 sites studied in London is not the same right across the UK.
