While nearly every motorist in the UK would back a Government ban on the use of hand-held mobile phones while driving, the fleet industry is already taking steps to make drivers safer.
A survey of business drivers showed that 87% were supplied with hands-free phones, compared to 38% of private drivers.
The survey also showed that two-thirds of companies enforced a hands-free only policy.
But the report also shows businesses are not doing enough to encourage drivers to use phones only while stationary.
One-quarter of drivers are under pressure to use their mobile phones while on the move with most (70%) saying that the pressure comes mainly from work.
The report follows Government consultation on introducing a ban on hand-held mobile phones while driving, which could lead to legislation being announced in the Queen's Speech next month.
The survey revealed that 91% of motorists back the proposals, even though most motorists think they can drive safely while taking a hand-held call. Three quarters of motorists believe putting on make-up (74%) and map reading (72%) are more dangerous than using a hand-held mobile phone.
RAC spokeswoman Ann Skey said: 'The Government should make sure any ban is backed by properly resourced police traffic patrols which are the best way of ensuring that we all stick to the rules.'
The survey backs another report on mobile phone use by TNS Telecoms, which found 93% of motorists supported a ban on hand-held phone use while driving.
