Fashion savvy drivers have been warned to ensure their sunglasses are legal when they get behind the wheel of their car.

Although motorists are urged to slow down or pull over if the sun is dazzling, there are some specs which may get them into bother with the law. Many, if they fall afoul of the rules, can even lead to several penalty points on people’s licences.

All sunglasses in the UK must be marked and labelled with a category number which are ranked from zero to four, which determines their strength and the time of day they can be safely worn. Most are labelled in category two - which have a slight tint and will transmit 18% - 43% of light - and are suitable for driving during the day.

However sunnies ranked category four come with a very dark tint and transmit just 3% - 8% of light, so are inappropriate for driving. These come with a label by law stating they are unsuitable for driving and road use.

Greg Wilson, Founder and CEO of said: “Carrying a spare pair of legal sunglasses in your glove box is essential during these brighter months – especially in the UK when we don’t know when the sun will appear. Wearing the right pair of sunglasses will help keep yourself and other road users safe this summer.

“Inappropriate eyewear could put you at risk of fines, penalty points or worse. Sunglasses are labelled in four categories to show if they’re suitable for road use. The average pair of sunnies are ‘category two’ and are therefore appropriate for driving.

“Any driver wearing inappropriate sunglasses could be subject to a dangerous driving charge, which potentially comes with hefty fines, penalty points and even prison time. If you are dazzled by the sunlight and it’s becoming too bright and dangerous to drive, make sure to slow down or pull over until it is safe to continue and don’t take the risk.

“It’s your responsibility to make sure your vision isn’t compromised. If you don’t protect your eyes properly from the sun and you have an accident, you could invalidate your car insurance.”

Rule 237 of the Highway Code states drivers should slow down or pull over if dazzled by the bright sunlight - so motorists should wear sunglasses to protect them whilst on the road.

However, drivers must also be aware certain sunglasses could be categorised as inappropriate depending on the tint level. The penalties for this offence reach up to 11 points on the licence, unlimited fines (£5,000 in Magistrate’s Court) as well as five years in prison.
