Drivers are being issued a warning over sunglasses and how a common mistake could earn them a hefty fine.
According to the Highway Code, motorists must slow down, or stop if they need to do so, when dazzled by sunlight. Anyone failing to do so could be fined up to £5,000.
However, some sunglasses can cause glare when driving. So experts are warning that your sunglasses may not be keeping you safer on the roads after all.
