Women are entreated by a road safety charity not to get behind the wheel in steep wedges, platform shoes or stilettos.
The charity, called Brake, has warned women that by driving in high heels they are putting not only putting themselves and others in danger.
"It is deeply worrying that many drivers have such little regard for their own and others' safety that they wear unsuitable footwear," the Daily Express quoted Julie Townsend, deputy chief executive as saying.
Her comments coincide with a survey which reveals 40 per cent of women drive in high heels.
Price comparison website Confused.com found 39 per cent wear flip-flops, 16 per cent wear slippers and 24 per cent drive in bare feet.
It also found that one in 10 women apply make-up while at the wheel and 15 per cent of men admit to shaving while driving.
"We need to bear in mind that a lapse of concentration at the wheel can lead to needless tragedy," the site's spokesman said.
