Drivers have been issued a warning to prepare for summer as they could be hit with four-figure fines and penalty points on their licence.
This is because of Rule 237 of the Highway Code, which says if you are dazzled by bright sunlight, slow down and if necessary, stop.
The motoring experts at Vanarama found that 37 percent of drivers have struggled to drive due to sun brightness at some point in the past.
This was after the car and van leasing company surveyed 1,000 British drivers and asked "What factors, if any, have affected your driving during the spring or summertime?"
The mistake puts motorists at risk of a £1,000 fine and 3 points for failure to have full a view of the road and traffic ahead.
Interestingly it was the over 55's that are struggling most with 42 percent of those aged 55 and over admitting this in Vanarama's new survey.
Bright sunlight can cause a strong glare across a car's windshield which can distort a driver's view of the road.
Your windows must be clean in the summer months to avoid magnifying glare, according to the Vanarama experts.
Andy Alderson, CEO, and Founder of Vanarama says: "To prevent being dazzled by the sun when driving, motorists should wear polarised sunglasses and keep a safe distance from other drivers when the sun is distorting their view.
"Creating space between you and the car in front will give you more time to assess the road situation. If drivers feel like they do not have full control of the situation, they should pull over when safe to do so.
"You must also keep your windscreen clean in the summer months. A dirty windscreen can magnify the sun's glare making it harder to see the road.
"Before heading out on car journeys in the sun, you should clean both the interior and exterior of the car windscreen, checking that they are free of any dirt and debris."
