Motorists in the UK are being advised to keep a crucial item in their glovebox to dodge potential fines and points this summer, as sun glare becomes an increasing hazard on British roads. With the sunny season on the horizon, drivers are encouraged to always have one essential accessory in their glovebox to potentially prevent hefty fines, penalty points, and bad driving conditions.

Experts at Bumper, specialists in car repair finance, are cautioning that abrupt bursts of intense sunlight can significantly impair drivers' visibility, underscoring the importance of being prepared. They recommend motorists "always keep a spare pair of legal sunglasses in your car" to avoid any issues.

Forgetting to replace your sunglasses after taking them out could cause difficulties not only for you but also for other road users.

A spokesperson from Bumper said: "Sun glare can appear suddenly and completely obscure your vision, especially during early morning or late afternoon driving. Having a spare pair of sunglasses within easy reach could be the difference between driving safely or committing a serious offence."

While there is no legal obligation to wear sunglasses when driving, Highway Code Rule 237 mandates that drivers must slow down or come to a safe stop if they are "dazzled by bright sunlight". Ignoring this advice could result in being charged with driving without due care and attention, which may include a £100 instant fine and three penalty points, reports Yorkshire Live.

The rule in full states: "Keep your vehicle well ventilated to avoid drowsiness. Be aware that the road surface may become soft or if it rains after a dry spell it may become slippery. These conditions could affect your steering and braking. If you are dazzled by bright sunlight, slow down and if necessary, stop."

For more severe cases, police can upgrade the charge to dangerous driving. This can result in fines of up to £5,000, increased penalty points, or even a driving ban.

"Being dazzled by the sun and continuing to drive without slowing down could be seen as reckless," spokesperson from Bumper added. "You don't need to be in a crash for it to be a legal issue - the risk alone can result in a penalty."

However, drivers should be cautious as not all sunglasses are suitable for driving. Wearing 'category four' dark-tinted lenses, fashion frames with small lenses, or glasses with large side arms could obstruct vision and lead to prosecution.

"Drivers need to be aware that some sunglasses are actually unsafe for road use," the spokesperson cautioned. "Stick to category two or three lenses, which reduce glare while maintaining clear visibility."

Those who already require prescription glasses should consider getting prescription sunglasses or anti-glare coatings, especially if their vehicles lack tinting or sun visors.

Alongside visibility issues, drivers are also being reminded to keep their vehicle documentation up to date — particularly when they move house. Failing to inform the DVLA of a change of address can result in a fine of up to £1,000.

This requirement applies not only to your driving licence, but also to your V5C logbook, car tax Direct Debit, and any documents linked to personalised number plates. It even extends to trailers used internationally.

“It's not just a matter of convenience — it’s a legal requirement,” said another Bumper worker. “Taking five minutes to update your address online could save you from a costly penalty.”
