In-car hands-free phone kits are a dangerous distraction that should be banned, according to nearly half of motorists polled by esure.
The company reports that 3,000 drivers in England and Wales were prosecuted in 2007 for failing to have proper control while using a kit to make calls.
And said Kevin Clinton, head of road safety at the Royal Society for the Prevention of Accidents: "Using a hands-free phone while driving is just as dangerous as using a hand-held phone.
"The use of phone kits should have been made illegal at the same time as hand-held phones were. We urge employers in particular to ensure their employees do not use any type of mobile phone when they are driving for work."
Mike Pickard, head of risk and underwriting at esure car insurance, said: "Any distraction that may compromise the concentration of motorists should be avoided as motorists need to have full control of their vehicle at all times.
"We urge motorists to either put their phones on silent when driving or, to remove the temptation of answering a call when behind the wheel, to make sure they switch off their phones until they have also switched off their engines."
