The figures from the DfT found that in 2014, 2.7% of van drivers were observed using a mobile phone, compared to 1.6% of all car drivers in England and Scotland.
The majority of van drivers were using a phone in their hand rather than holding it to their ear; 1.9% of van drivers in England and Scotland were observed holding a phone in their hand compared with 0.7% observed holding the phone to their ear.
Commenting on the release of the DfT study, Professor Stephen Glaister, director of the RAC Foundation, said: “These figures are a worry. In 2013 the use of a mobile at the wheel was a factor in 22 fatal accidents and this is likely to be underreporting of the true figure.
“Research for us shows that texting whilst driving impairs reactions more than being at the drink drive limit. The disproportionate number of van drivers using mobiles appears to highlight the time pressures many are under and their likely use of mobile devices to check pick up and drop off destinations.
‘The big concern is that with more and more technological and visual distractions in our lives and in our vehicles the risks will increase.”
Neil Greig, IAM director of policy and research, added: "The results are very disappointing but not at all surprising. Campaigners routinely talk about the inherent dangers of the distraction caused by mobile phone usage, but drivers never believe they will be caught.
“Campaigns run by THINK! and the Department for Transport need to be revived and invigorated with stronger messages for new drivers and van users. Mobile phone usage at the wheel can kill – there’s no two ways about it.
“Tackling mobile phone usage must be a government priority for 2015. People must have the fear of being caught increased as we believe this is the only viable deterrent, but that needs an increase in visible policing.”
