A new law which would make it an offence for drivers to use hand-held mobile phones is likely to extend to employers who cause or permit the use of such devices by their employees while driving.
The Department for Transport concluded its consultation on the proposed new offence last month and is expected to bring legislation into effect early next year.
Company car drivers have been shown to be among the worst culprits for using mobiles phones while at the wheel and pressure is growing for employers to take action.
"We want to see employers introducing clear policies to stop their workers using mobile phones at the wheel, whether hand-held or hands-free," said Kevin Clinton, head of road safety at safety campaign group Rospa. "They should do this as part of their policies to manage occupational road risk and under their responsibilities to keep their employees safe."
The new law will also prohibit the use of hand-held phones used with an earphone and microphone, leaving employers to pick up the tab for fitting company cars with dashboard mountings for hands-free kits.
