Should you drive in bright sunshine without glasses? Read to our tips to avoid accidents. Don't get caught out!
So, we've recently been having a spot of sun but what are the rules for wearing sunglasses when driving? It seems a simple question but there's a bit more to it.
Motoring experts advise keeping a pair of sunglasses in your car to pop on when the sun is out and to avoid glare. But what if you don't have them to hand? According to the Highway Code, drivers should pull over or slow down if dazzled by sunlight. So be aware that if you are driving and you are faced with bright sunlight but don't have your sunglasses with you and you don't slow down or pull over - and the sun causes you to take your eyes off the road, albeit momentarily - you could be in danger of driving without due care and attention.
Maybe you are a "sun-sneezer"? i.e. when you sneeze in the presence of bright light, especially sunlight? This phenomenon affects about 10%-35% of the population. If you feel you are about to sneeze, slow down and drop back - at 70mph you will lose vision for about 100m!
If you do opt to wear sunglasses, make sure the lenses are not too dark. Filter category 4 lenses only transmit between 3% and 8% of light and are not suitable for driving at any time. Sunglasses with these lenses should, by law, be labelled 'Not suitable for driving and road use'. Due to the light levels within the car, filter category 2 lenses which transmit between 18% and 43% of light are recommended for daytime driving.
