Drivers may be stunned to learn that wearing the wrong kind of sunglasses behind the wheel could land you with a hefty fine.
Some sunglasses can cause a dazzling glare to other motorists on the roads. According to the Highway Code, drivers must slow down - or stop if they need to do so when dazzled by sunlight - and anyone failing to do so could be fined up to £5,000.
Using tinted glasses, lenses and visors at night or in poor visibility is also prohibited if they restrict your vision, with penalties ranging from points on your license, an unlimited fine, and even potential disqualification.
