A new study has found that drivers aren’t alert to the dangers posed by UV exposure when they get behind the wheel – and millions are getting sunburnt
Millions of Brits are unknowingly putting themselves at risk of sunburn every time they get behind the wheel. New research has found that 47% of motorists take no precautions against UV exposure despite an estimated 14million experiencing sunburn while travelling by car.
Around one in three (31%) said they didn’t even realise it was possible to get sunburnt inside a vehicle, according to the survey by Autotrader and the British Skin Foundation. While modern windscreens block the vast majority of UVB radiation, many side windows can still allow significant levels of UVA rays into the vehicle.
Dr Zainab Laftah, consultant dermatologist and spokesperson for the British Skin Foundation, said: “A common misconception is that being inside a vehicle provides complete protection from the sun.
“In reality, both short periods of intense UV exposure and repeated exposure over time contribute to an increased risk of skin cancer.
“While standard car windscreens block most UVB radiation, the amount of UVA that enters a vehicle varies depending on the type, thickness and tint of the glass.
“This means a significant amount of UVA can still penetrate vehicle windows, contributing to cumulative skin damage, premature skin ageing, pigmentation changes and an increased risk of skin cancer over time.”
While UVB rays are those primarily responsible for sunburn, UVA rays can cause deep skin damage and heighten the risk of skin cancer.
Dr Laftah’s warning comes as demand for open-top motoring rises with the temperature. During the May heatwave, searches for convertibles on Autotrader increased by 8 per cent week-on-week, with models including the Porsche 911, Mazda MX-5 and Mercedes-Benz SL among the most-viewed vehicles on the platform.
She said that those driving convertibles need to be even more wary – and take care they know how long they are spending in the sun.
“Many drivers also underestimate how long they’re exposed during everyday journeys, particularly on longer drives or when sitting in traffic,” she said.
“For drivers of convertibles and other open-top vehicles, the risk is even greater because the face, scalp, neck, arms and hands are exposed to direct sunlight for prolonged periods.”
The stark warning follows separate British Skin Foundation research from 2025 which found that a third of Brits had already been sunburnt by early summer. The same proportion (31%) admitted they simply “couldn’t be bothered” to wear sunscreen in sunny weather.
Rory Reid, YouTube director at Autotrader, continued: “Nothing beats driving with the roof down on a sunny day, and every time the weather improves, we see demand for convertibles climb.
“What many people don’t realise is that spending time behind the wheel can expose them to harmful UV rays, even inside the car.
“Whether you’re driving to work, heading off on holiday or simply enjoying the sunshine, applying sunscreen should be as much a part of your journey as checking your tyre pressures, topping up your screen wash or making sure you’ve got water in the car.”

How to stay safe behind the wheel
- Apply a broad-spectrum sunscreen with SPF30 or higher to all exposed skin at least 15 minutes before setting off, paying particular attention to often-forgotten areas including the ears, neck, scalp, hands and forearms.
- Reapply sunscreen during longer journeys, particularly if you’re spending extended periods behind the wheel.
- Consider UV-filtering window films if you drive frequently or spend long periods in the car.
- If driving a convertible or other open-top vehicle, keep the roof up during peak UV hours (12pm–2pm) where possible, wear protective clothing and ensure all exposed skin is covered with high-factor sunscreen.
- Wear UV-protective sunglasses to protect both your eyes and the delicate skin around them.
